Improbable Destinies: An interview with Jonathan B. Losos

Jonathan B. Losos with his favourite research subject: the green anole

Jonathan B. Losos is an evolutionary biologist, currently at Harvard University. He is best known for his research on speciation in Caribbean anoles, a genus of iguanian lizards. Previously, he has authored Lizards in an Evolutionary Tree: Ecology and Adaptive Radiation of Anoles. His latest book, Improbable Destinies: How Predictable is Evolution?  is an incredibly enjoyable romp through evolutionary biology, examining the phenomenon of convergent evolution (i.e. the process by which different organisms have evolved the same or similar traits independently over time), and asks the question: how repeatable is evolution really? After reading this book recently (see also the review I left for the book) I contacted Jonathan to talk some more convergent evolution with him.

1. As a biologist, I can understand your fascination with convergent evolution. But to introduce yourself to the readers, what drew you to study this one topic out of all the fascinating aspects of evolution? Was this interest there from the beginning, or did you chance on it as your research progressed?

I’ve been interested in convergence ever since I learned about evolution because convergence of species living in similar environments is such a great demonstration of the power of natural selection. However, when I conducted my doctoral work on Caribbean Anolis lizards, I truly became fascinated by the phenomenon.

2. In your preface, you write how your PhD project on lizard diversification in the Caribbean supported ideas on convergent evolution. Right after writing up your thesis, Gould published his book Wonderful Life, in which he stressed the importance of contingency, arguing that evolution is unpredictable. You write you were taken with his book. How did you go about reconciling Gould’s views with your own?

Evolutionary biology is unlike most sciences in that it is a historical science. We can’t just do a key experiment or derive an equation and solve the problem. Rather, like detectives, we have to build the best case to understand what happened in the past. In addition, as Ian Malcolm said in Jurassic Park, life finds a way. In fact, evolution occurs in myriad different ways – almost any way of evolving you can imagine has occurred somewhere, some time. In this way, evolution is an inductive sciencewe can’t derive general rules for first principles; rather, we have to go out in nature and develop many case studies. Only in that way can we recognize the general patterns from the interesting exceptions.

It is in this light that I reconciled my one research on Anolis lizards, which indicated that evolution has travelled very much the same course four times on the different islands of the Greater Antilles (the large islands of the Caribbean), with Gould’s ideas that evolution, for the most part, is unpredictable and unrepeatable. I considered the Anolis situation to be one of the exceptions, fascinating, but out of the ordinary.

3. Part two of your book describes a plethora of field studies, including your own work on Anolis lizards, which by and large show that evolution is repeatable. Some people, botanists especially, have raised the objection that such findings could also come about by phenotypic plasticity. You have addressed this objection yourself experimentally and found that phenotypic plasticity only plays a limited role. Have others done the same, and is this something that is routinely considered and excluded as a possible explanation in this kind of research?

Phenotypic plasticity – the ability of genetically identical individuals to produce different phenotypes when exposed to different environmental conditions – has long been known. However, until recently, it was mostly considered to be noise in the system, non-adaptive phenomena that mostly served to prevent natural selection from producing evolutionary change (the reason being that natural selection might favor one variant, but if different variants in a species were genetically identical, then selection wouldn’t lead to any evolutionary change). However, in recent years we have realized that plasticity may be an important part of the evolutionary process. Although phenotypic variation (i.e., variation in traits such as anatomy, physiology) among individuals in a population may not be genetically based, the ability of a species to produce different phenotypes in different conditions is itself a genetically based trait that may evolve adaptively. Thus, species may evolve to exhibit great phenotypic variation as a response to living in many different environments. As a result, the amount of research on phenotypic plasticity has skyrocketed in the last two decades.

4. Towards the end of Part Two, you point out another weak point of most field experiments. They generally start off with genetically related populations and so are likely to be predisposed to generate parallel evolutionary responses. Furthermore, statistical analyses might filter out the exceptions to the rule. Has experimental work by now moved on to using genetically dissimilar starting populations to investigate if convergent evolution is powerful enough to funnel different populations towards the same evolutionary outcome?

I wouldn’t say that this is a weak point of field experiments. Rather, it is a consequence of the hypothesis that is being tested. If you want to understand why guppies evolve to be more colourful in the absence of predators, then the appropriate experiment is to create multiple replicate populations of guppies in different conditions and see what happens. But, as I wrote in the book, we would expect very similar, closely-related populations to evolve similar adaptive responses to the same questions. One approach would be to conduct parallel experiments on many different species of fish to see the extent to which they adapt in similar ways (or in differing ways). Right now, I’m unaware of anyone doing this. However, different researchers sometimes ask the same question with different species, and this is the most likely way we will be able to address this question.

5. Part Three of your book looks at long-term laboratory experiments with bacteria. It seems here too, results initially suggested convergent evolution is the rule. Until exceptions starting cropping up on the longer term. Does the answer to the question whether evolution is repeatable depend on the timescale over which you look? Are we too focused on the short-term if we conclude that convergent evolution is the rule, rather than the exception?

That’s a keen observation. In Rich Lenski’s Long-Term Evolution Experiment, the story after 14 years was that evolution is pretty repeatable. Then, 30,000+ generations into the experiment, one of 12 experimental lines evolved a very different adaptation, one that still hasn’t been matched in the other 11 lines after another 14 years. So, yes, the longer one conducts a study, the greater the chance that rare, unique adaptations will occur (and we must remember that 30,000 generations are a drop in the evolutionary bucket). On the other hand, as Rich Lenski himself says, if the LTEE is continued long enoughmaybe for 300,000 generations – then perhaps the other 11 populations will discover the new adaptive solution as well. So, yes, definitely, these studies need to be continued much longer. Most studies today, LTEE’s fame and influence notwithstanding, are much shorter in length (note: Loses and Lenski edited the book How Evolution Shapes Our Lives. ed.).

6. You conclude your book by saying that in the short term evolution is predictable, but that the world of biological possibilities is a vast one, and that in the long term, chance events have had a large impact. Given the many books dedicated to the topic of convergent evolution, and the way it speaks to people’s imagination, do you think we have overestimated the importance of this mechanism? Are we too keen on seeing patterns where there are none?

Well, we need a bit of historical perspective on this question. Until recently, we thought of convergent evolution as relatively rare. Great examples of the power of natural selection, worthy of being in biology textbooks, but not at all common. Now, thanks to the work of Simon Conway Morris and others, we realize that convergence is much more pervasive than we used to believe. This has been a valid contribution to our understanding of evolution. Nonetheless, some workers have gone too far, in my estimation, in emphasizing the importance and prevalence of convergent evolution. It is a common and important aspect of evolution, but it is not the only story.

The Evolution–Intelligent Design Circus

This post is the third of a four-part series on polarised discussions in science and how to deal with misinformation. You can find Part 1 introducing the topic here, Part 2 on climate change here,  and Part 4 on dealing with misinformation here.


Ever since Darwin published On the Origin of Species (1859; 150th Anniversary Edition, Darwin & Endersby, 2009), his ideas have been much debated. There have been many scholars over the years who disagreed with some or all of his ideas, and the history of this is charted in books such as Defining Darwin: Essays on the History and Philosophy of Evolutionary Biology (Ruse, 2010), Darwin’s Dangerous Idea: Evolution and the Meanings of Life (Dennett, 1995), The Non-Darwinian Revolution: Reinterpreting a Historical Myth (Bowler, 1988), and The Eclipse of Darwinism: Anti-Darwinian Evolution Theories in the Decades Around 1900 (Bowler, 1983). These academic discussions and disagreements have Evolution: The First Four Billion Yearsbeen absolutely vital to further the development of evolutionary theory and push the discipline as a whole forwards. Books such as Evolution: The Modern Synthesis (Huxley, 2010), Evolution: The Extended Synthesis (Pigliucci & Müller, 2010), Evolution: The History of an Idea (Bowler, 2009), and Evolution: The First Four Billion Years (Ruse & Travis, 2009) give a tremendous overview of the historical development of the field over the last century.

From the outset, however, there has also been an intense clash between evolutionary theory and religion, especially in America, both in general (see for example The Book That Changed America: How Darwin’s Theory of Evolution Ignited a Nation (Fuller, 2017)), but especially with the fundamentalist Christian school of thought of Creationism. The Oxford dictionary defines this as ‘The belief that the universe and living organisms originate from specific acts of divine creation, as in the biblical account, rather than by natural processes such as evolution’. It was Darwin himself who, in an 1856 letter to Joseph Dalton Hooker, dubbed its proponents, who objected to the emerging science of evolution on religious grounds, Creationists.

A particularly notable and influential episode that had enormous consequences was the 1925 Scopes trial, in which American high school teacher John T. Scopes was accused of violating Tennessee’s Butler Act, which had made it unlawful to teach human evolution in state-funded schools (see The Scopes Monkey Trial (Moore & McComas, 2016), and The Scopes Trial: A Brief History with Documents, though for an alternative interpretation offering, in the words of the publisher ‘an apologetic for divine creation’, see Monkey Business: True Story of the Scopes Trial (Olasky & Perry, 2005)). He was found guilty, though not convicted, and the trial escalated the conflict between strict creationists and scientists regarding the extent to which evolution would be taught as a science subject in schools. Trying Biology: The Scopes Trial, Textbooks, and the Antievolution Movement in American Schools (Shapiro, 2013) provides a wider historical context to The Creationiststhe trial. The matter of teaching evolution remains contested to this day. After the US Supreme Court in 1987 forbade teaching creationism in public schools on the grounds it violated the separation of church and state, Creationists rebranded their ideas to Intelligent Design, or ID for short (see Creationism’s Trojan Horse: The Wedge of Intelligent Design (Forrest & Gross, 2007)). These efforts have been fronted by, yet again, a conservative think tank, here the Discovery Institute. There are several books charting the controversies since the Scopes trial, for example Intelligently Designed: How Creationists Built the Campaign Against Evolution (Caudill, 2013), American Genesis: The Evolution Controversies from Scopes to Creation Science (Moran, 2012), Darwinism and its Discontents (Ruse, 2006), and the exhaustive The Creationists: From Scientific Creationism to Intelligent Design (Number, 2006). Also noteworthy is Randy Olson’s even-handed 2006 documentary Flock of Dodos: The Evolution-Intelligent Design Circus.

As the US Supreme Court forbade the teaching of Creationism on the grounds of it being a religion, ID proponents argue theirs is an evidence-based scientific theory. In their view, certain complex features of the universe and living beings are irreducibly complex, and thus proof for the existence of a divine creator. These ideas are elaborated in books such as Undeniable: How Biology Confirms Our Intuition That Life Is Designed (Axe, 2016), Evolution: Still a Theory in Crisis (Denton, 2016), Darwin’s Doubt: The Explosive Origin of Animal Life and the Case for Intelligent Design (Meyer, 2013; Stephen Meyer is the head of the Discovery Institute), Signature in the Cell: DNA and the Evidence for Intelligent Design (Meyer, 2010), and Darwin’s Black Box: The Biochemical Challenge to Evolution (Behe, 1995; considered by many the foundational text for the ID movement).

Many biologists have widely criticised ID, and it is generally considered as a pseudoscience. See amongst others Inside the Human Genome: A Case for Non-Intelligent Design (Avise, 2010), Why Evolution is True (Coyne, 2009), The GThe Greatest Show on Earthreatest Show on Earth: The Evidence for Evolution (Dawkins, 2009), Why Evolution Works (and Creationism Fails) (Young & Strode, 2009), The Panda’s Black Box: Opening Up the Intelligent Design Controversy (Comfort, 2007), Scientists Confront Creationism: Intelligent Design and Beyond (Petto & Godfrey, 2007), Doubting Darwin?: Creationist Designs on Evolution (Sarkar, 2007), Intelligent Thought: Science Versus the Intelligent Design Movement (Brockman, 2006), Why Darwin Matters: The Case Against Intelligent Design (Shermer, 2006), The Counter-Creationism Handbook (Isaak, 2005), God, the Devil, and Darwin: A Critique of Intelligent Design Theory (Shank, 2004), or Why Intelligent Design Fails: A Scientific Critique of the New Creationism (Young & Edis, 2004). Even earth scientists have felt the need to speak out (For the Rock Record: Geologists on Intelligent Design (Schneiderman & Allmon, 2009)). Several books deal specifically with claims that fossil evidence of transitional forms is lacking (Evolution: What the Fossils Say and Why it Matters (Prothero, 2007; second edition, 2017)), or the idea that evolution Evolution: What the Fossils Say and Why it Mattersreveals a grander design (Darwin and Design: Does Evolution Have a Purpose? (Ruse, 2003), and The Blind Watchmaker: Why the Evidence of Evolution Reveals a Universe Without Design (Dawkins, 1976; 40th Anniversary Edition, 2016)). For contributions hypothesising how complexity might have emerged naturally, see for example The Arrival of the Fittest: Solving Evolution’s Greatest Puzzle (Wagner, 2014), or The Tinkerer’s Accomplice: How Design Emerges from Life Itself (Turner, 2007).

Many hard-line scientists, Richard Dawkins included, argue that there is no debate to be had in the first place. There is no point arguing facts with a believer. Engaging these beliefs, and, as the Discovery Institute would have it, ‘teaching the controversy’, merely provides legitimacy to a non-existent controversy (though see Teaching Evolution in a Creation Nation (Laats & Siegel, 2016) for a proposition on how to break the Science and Religiondeadlock between science and religion). This touches on the age-old question of what dialogue there can be between science and religion. Dawkins, known for his militant atheism, is outspoken on the matter in his polemical The God Delusion (2006; 10th Anniversary Edition, 2016), while other authors have branded this as a futile effort (see for example Science and Religion: An Impossible Dialogue (Gingras, 2017) and Faith Versus Fact: Why Science and Religion Are Incompatible (Coyne, 2015)).

Amidst this fierce debate between two extremes, it is easy to overlook there are more moderate ideas. Many religious people do not support a literal reading of holy texts, and supporters of theistic evolution hold that religion and evolution need not contradict each other. The argument that geneticist Francis Collins puts forth in The Language of God (2006) boils down to “evolution is real, but it is the hand of God”. And he is not alone, Monkey Trials and Gorilla Sermons: Evolution and Christianity from Monkey Trials and Gorilla SermonsDarwin to Intelligent Design (Bowler, 2007) traces the long history of how churches have sought to reconcile Christian beliefs and evolution, and see ‘reflections of the divine in scientific explanations for the origin of life’. Whether you agree with this or not (religious fundamentalists see it as a capitulation, while Dawkins in The Blind Watchmaker has called it a superfluous attempt to ‘smuggle God in by the back door’), this rapidly leaves the realm of scientific enquiry and becomes one of personal beliefs.

On Truth and Post-Truth in Science

This post is the first of a four-part series on polarised discussions in science and how to deal with misinformation. You can find Part 2 on climate change here, Part 3 on evolutionary biology here, and Part 4 on dealing with misinformation here.


Oxford Dictionaries
proclaimed ‘post-truth’ as the international ‘word of the year’ in 2016, on the back of Michael Gove’s ‘Britain has had enough of experts – a defining moment of last year’s BREXIT referendum – and the incessant flow of claims and counter-claims during the US presidential election. It’s kept the commentariat busy, giving rise to at least one superb analysis (listen in to Jo Fidgen on the BBC Radio 4’s Nothing But the Truth) and some dark humour (the spoof ‘Mordor National Park’ twitter account set up in January, ‘We’d like to repeat again that yes, open campfires are allowed in Mordor National Park. Everything here is on fire.’).

But in the world of books on evolution, ecology, conservation, and climate change, ‘post-truth’ is not new. It’s 16 years since the publication of the first English edition of Bjørn Lomborg’s The Skeptical Environmentalist: Measuring the Real State of the World (2001), which (publisher’s blurb) ‘challenges widely held beliefs that the environmental situation is getting worse’; 36 years since Julian Simon wrote The Ultimate Resource (1998), arguing that humanity is not running out of natural resources; and 158 years since Charles Darwin unveiled his theory of evolution in On the Origin of Species (1859; 150th Anniversary Edition, Darwin & Endersby, 2009), triggering intense debate, disagreement, vitriol and accusations of lying that make today’s disputes look positively placid by comparison.

Our view on these issues is at once simple and complicated. As a company we are staunch believers in evolutionary theory, and the truth of findings from climate science that show how dangerous global warming is a consequence of humanity’s burning of fossil fuels, and of the loss and degradation of forests and other terrestrial ecosystems. But our staff and our customers will have their own views; as is right and proper.

Our purpose in this four-part series is to highlight recent publications that help readers think more critically, recognise pseudoscience, and deal with the large amount of spin, misinformation, and created controversies that pollute these discussions. In the process, we will give a brief overview of two areas that are the subject of intense and polarised public debate: climate science and evolution. As we wish to inform rather than rant, our selection of books includes views from various sides of the debates. Lest there be any doubt in the mind of the reader, this does not mean that we endorse all these views, or are planning to catalogue a wider range of books to give a platform to them. But, for the purpose of this piece, we feel we would do the reader no service by ignoring their existence.

Book Review – Turtles as Hopeful Monsters

Turtles as Hopeful MonstersTurtles as Hopeful Monsters: Origins and Evolution

Written by Olivier Rieppel

Published in hardback by Indiana University Press in March 2017 in the Life of the Past series

Turtles have long vexed evolutionary biologists. In Turtles as Hopeful Monsters, Olivier Rieppel interweaves vignettes of his personal career with an overview of turtle shell evolution, and, foremost, an intellectual history of the discipline of evolutionary biology.

An initial, light chapter serves to both introduce the reader to important experts on reptile evolution during the last few centuries, as well as give an account of how the author got to study turtles himself. After this, the reading gets serious though, and I admit that I got a bit bogged down in the second chapter, which discusses the different historical schools of thought on where turtles are to be placed on the evolutionary tree. An important character here is skull morphology and a lot of terminology is used. Although it is introduced and explained, it makes for dense reading.

I think the book shines in the subsequent chapters that give a tour of the evolution of, well, evolutionary thinking.

When Darwin formulated his theories, he argued that evolution is a slow and step-wise process, with natural selection acting on random variation to bring about gradual change. This is the transformationist paradigm. Turtles as Hopeful Monsters, page 53The fossil record has yielded some remarkable examples where a slow transformation has occurred over time, such as the development of hooves in horses. But equally, there are many examples where no such continuous chain exists in the fossil record. Turtles are one such example, as they just suddenly appear in the fossil record, shell and all. Darwin himself attributed this to ‘the extreme imperfection of the fossil record‘. This lack of transitional fossils has of course been eagerly exploited by the creationist / intelligent design movement for their own ends.

But ever since Darwin, biologists have argued, and still do, that there exist mechanisms that allow for rapid innovation and saltatory evolution (i.e. evolution by leaps and bounds). This is the emergentist paradigm. Rieppel gives an overview of the different theories that have been put forward over the last two centuries, which is both illuminating and amusing. This covers such luminaries as Richard Goldschmidt (who coined the phrase “hopeful monsters”), Stephen Jay Gould (who revived it), and Günter Wagner (who provides the best current explanation according to Rieppel).

Just a little bit more about this phrase “hopeful monsters”, as this is such a prominent part of the book’s title. According to Goldschmidt, major new lineages would come about through mutations during early development of the embryo. This, of course, has the risk of producing monsters when the organism matures, likely resulting in premature death. So, Goldschmidt proposed a theory of hopeful monsters, where such drastic changes would successfully result in new evolutionary lineages with new body plans. His explanations, which required evolution to be goal-directed and cyclical (so-called orthogenetic evolution) have become obsolete, but he wasn’t entirely off the mark either. The best current explanations, according to Rieppel, comes from Wagner (author of Homology, Genes, and Evolution) and others who suggest radical changes to body plans do originate at the embryonic stage, and that the cause is the rewiring of the underlying genetic mechanisms.

Turtles as Hopeful Monsters, page 181The final two chapters of the book show how the debate over turtle shell evolution has gone back and forth between these two paradigms over time. Here again, Rieppel goes quite deep into morphology, this time of the shell, with accompanying terminology. Although the consensus seems to be leaning towards changes in embryonic development being responsible for the sudden appearance of the turtle shell in the fossil record, the final chapter deals with recent fossil finds from southwestern China that have revealed a potential missing link: a turtle with a fully developed belly shield.

Overall then, this book is a highly enjoyable romp through the intellectual history of evolutionary biology, using turtle evolution as its red thread. I could have used a bit more hand-holding here and there, and I feel the book would have benefited from an (illustrated) glossary or some extra illustrations. The reading gets quite technical when Rieppel goes into expositions on skull and shell morphology. That said, this book is an excellent addition to the popular science works in the Life of the Past series.

Book Review – How to Tame a Fox (and Build a Dog)

How to Tame a Fox (and Build a Dog)How to Tame a Fox (and Build a Dog): Visionary Scientists and a Siberian Tale of Jump-Started Evolution

Written by Lee Alan Dugatkin & Lyudmila Trut

Published in March 2017 by Chicago University Press

How to Tame a Fox (and Build a Dog) tells a remarkable story about a remarkable long-term experiment you will most likely never have heard of. I hadn’t, despite my background in evolutionary biology. When the announcement for it crossed my desk a month or so ago, its subtitle immediately grabbed my attention.

For more than 60 years, Russian scientists have been cross-breeding captive foxes in Siberia, selecting for tameness, in a bid to learn more about the evolutionary history of animal domestication. Written by evolutionary biologist and science historian Lee Alan Dugatkin and Lyudmila Trut, who has been part of this experiment for close to six decades, it tells the story from its inception.

Back in 1952, geneticist Dmitri Belyaev had many questions regarding domestication. Though the breeding techniques were well understood, how did domestication start? The wild ancestors of today’s domestic animals would have likely run away or attacked humans, so what changed to make domestication possible? Being the lead scientist at a state laboratory that helped fur breeders produce more beautiful and luxurious fox pelts, he had both the knowledge and the means to tackle these questions. His plan? Experimentally mimic the evolution of the wolf into the dog using its close genetic cousin the fox. It was bold, both in its timescale, likely needing years – even decades – to yield results, but also in its timing. You see, Russia was still under the communist rule of Stalin, and one of his protegees, the poorly educated agronomist Trofim Lysenko, was waging a war on the “western” science of genetics. Scientists were expelled, imprisoned, and even murdered over their career choice. But Belyaev, having lost a brother this way, refused to back down. Far from Lysenko’s prying eyes in Moscow, in the frozen wilderness of Siberia, he started his breeding experiments, purporting to improve breeding rates in case anyone did come asking. Lyudmila joined him in 1958, and this book is their story.

It’s a story of science, and the authors do a good job distilling the findings into a reader-friendly format. The results are fascinating as the foxes rapidly evolve from wild animals to tamer and tamer companions that crave human interaction, undergoing a raft of subtle morphological changes in the process. But it’s also very much a human story. Of the women, often local peasants, who came to work at the fox farm, not necessarily understanding the science, but showing immense dedication to the cause. Of the researchers, who developed a deep love for, and connection with the generations of foxes, who rapidly became more dog-like in their behaviour and appearances.

It’s a story of persistence against all odds; the experiments are running to this day and have survived Stalin’s brutal regime, the Cold War, and the dissolution of the Soviet Union, with all the economic turmoil that that caused. And it’s a story of an opportunity most scientists can only dream of: being able to follow up on previous findings and answering questions raised by previous experiments. Uniquely, this played out during (or perhaps was able to keep going because of) a period in which our knowledge of genetics, and the technologies available, kept on developing. The measuring of neurochemicals, epigenetics, PCR, genome mapping, next-generation sequencing… as new questions were being generated, so new techniques became available to probe deeper into the mysteries of the domestication.

The book makes for fascinating reading and is hard to put down once you start it. Highly recommended.

What?

New volume in the MIT Press Vienna Series in Theoretical Biology.

Why?

Following the ethos of this series which looks in detail at the theoretical models behind the practical application of the biological sciences, this new volume looks at the phenomenon of convergent evolution through its manifestation in animal and plant biology, as well as in natural systems of all scales from the molecular world to large-scale ecosystems, and finally extending into the realm of mind where convergent characteristics are found in phenomena like tool use, and the evolution of various behaviours such as reproduction and herding.

This is a fascinating account of the state of current thinking on this subject, which brings into perspective the possibilities of life on our planet and Darwin’s vision of “endless forms most beautiful”.

Darwin’s Bicentenary and the History of Evolutionary Biology

It’s almost the 200th anniversary of Darwin’s birth (February 12th 1809) and 150 years since the publication of On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, his ground-breaking theory on the evolution of populations by means of natural selection.

To celebrate Darwin’s Bicentenary we have a selection of books written by Darwin, including his seminal On The Origin of Species, The Voyage of the Beagle and The Descent of Man. There is also a wide range of books about Darwin, a section on the history of Evolutionary Biology and our pick of introductory evolutionary biology books for the non-scientist.

We have also put together a summary of the latest titles in evolutionary biology and the Evolution Classics and Bestsellers – our pick of the most important books on evolution from the last 40 years.
