I’m an evolutionary biologist and a Wenner-Gren Fellow at the Evolutionary Biology Centre at Uppsala University, Sweden. My research focuses on the biology of genetic conflicts and what they can tell us about the evolution of conflict and cooperation more generally. I develop population genetic theory and perform comparative analyses to ask how and why such conflicts occur and how they fit into models of social evolution. I also work on the foundations of the so-called gene’s-eye view of evolution, also known as selfish gene theory. I studied at Edinburgh and Toronto and was a postdoc at Cornell and Harvard.
Few phrases in biology have caught the imagination of professionals and laypeople alike the way Richard Dawkins's ‘selfish gene’ has done, and it changed how both groups thought about evolution. The debate over the value of taking a gene’s-eye view of evolution has raged for over half a century and it pitted 20th-century Darwinian heavyweights such as John Maynard Smith and W.D. Hamilton against Richard Lewontin and Stephen Jay Gould in the pages of Natureas well as those of The New York Review of Books. My book is about that debate and I explore the origins and developments of the gene's-eye view: what it is, where it came from, how it changed, and why it still evokes such strong emotions.
When I read Richard Dawkins’s The Extended Phenotype I knew I wanted to become an evolutionary biologist. The book is the most ambitious articulation of the gene’s-eye view (a work of ‘unabashed advocacy’, as Dawkins put it). Less famous thatThe Selfish Gene, it also includes responses to the criticisms thatThe Selfish Genereceived, which also made debates in theoretical biology seem so exciting. In many ways, that excitement has never left me.
In The Selfish Gene, Richard Dawkins crystallized the gene's eye view of evolution developed by W.D. Hamilton and others. The book provoked widespread and heated debate. Written in part as a response, The Extended Phenotype gave a deeper clarification of the central concept of the gene as the unit of selection; but it did much more besides. In it, Dawkins extended the gene's eye view to argue that the genes that sit within an organism have an influence that reaches out beyond the visible traits in that body - the phenotype - to the wider environment, which can include other…
The gene’s-eye view of evolution emerged in the 1960s and 1970s. Arguing that biologists are better off thinking about evolution in terms of genes rather than organisms was controversial, but still quickly gained popularity. An important reason for this was that it helped make sense of old, long-standing problems in the field. Two of those were sexual selection (how extravagant traits like the peacocks tail can evolve) and altruism (like the sterile worker ant devoting its life to the queen). In The Ant and the Peacock, Helena Cronin shows how the gene’s-eye view provides a powerful way to solve these puzzles.
This book is a success story. It explains two long-running puzzles of the theory of natural selection. How can natural selection favour those, like the ant, that renounce tooth and claw in favour of the public-spirited ways of the commune? How can it explain the peacock's tail, flamboyant and a burden to its bearer; surely selection would act against useless ornamentation? Helena Cronin's enthralling account blends history, science and philosophy in a gripping tale that is scholarly, entertaining and eminently readable. The hardback edition was selected by Nature as one of the best scientific books in 1992. Also the New…
The theory of evolution touches us in a way other scientific theories do not. It deals directly with who we are and where we come from. But how exactly?The Selfish Gene came out only a year after E.O. Wilson’s Socbiology and both books helped ignite an ill-tempered debate over this question. Ullica Segerstråle's book is a comprehensive history of this particularly intense disagreement and is full of personal anecdotes and insights from all the major players.
For the last twenty-five years, sociobiologists have come under continuous attack by a group of left-wing academics, who have accused the former of dubious and politically dangerous science. Many have taken the critics' charges at face value. But have the critics been right? And what are their own motivations? This book strives to set the record straight. It shows that the criticism has typically been unfair. Still, it cannot be dismissed as 'purely politically motivated'. It turns out that the critics and the sociobiologists live in different worlds of taken-for-granted scientific and moral convictions. The conflict over sociobiology is best…
I did my PhD in biology, but one of the books that affected my thinking the most was written by a philosopher: Samir Okasha’s Evolution and the Levels of Selection. I came to biology not through a love of natural history, but through a fascination with the logic of evolution by natural selection. The debate over the gene’s-eye fitted perfectly into this and it led me into the huge literature in the philosophy of biology that deals with the so-called levels of selection debate – does natural selection act on genes, individuals, or groups? Okasha’s book is a great demonstration of how philosophy can help science.
Does natural selection act primarily on individual organisms, on groups, on genes, or on whole species? Samir Okasha provides a comprehensive analysis of the debate in evolutionary biology over the levels of selection, focusing on conceptual, philosophical and foundational questions. A systematic framework is developed for thinking about natural selection acting at multiple levels of the biological hierarchy; the framework is then used to help resolve outstanding issues. Considerable attention is paid to the concept of causality as it relates to the levels of selection, in particular the idea that natural selection at one hierarchical level can have effects that…
The biggest strength of the gene’s-eye view is that it helps us make sense of things that seem impossible to understand from the perspective of individual organisms. One example is selfish genetic elements. These are genes that in one way or another have hijacked the system by which genes are replicated and passed on to the next generation. This ability allow them to spread in a population, even if they are harmful to the organism that carries them. I was given Burt and Trivers's book as an undergraduate by the professor who would later become my PhD advisor. That was over ten years ago, but every time I pick up this book I am reminded of how awestruck I was. Selfish genetic elements and genetic conflicts are a weird and wonderful world andGenes in Conflict is the best guide there is.
In evolution, most genes survive and spread within populations because they increase the ability of their hosts (or their close relatives) to survive and reproduce. But some genes spread in spite of being harmful to the host organism-by distorting their own transmission to the next generation, or by changing how the host behaves toward relatives. As a consequence, different genes in a single organism can have diametrically opposed interests and adaptations.
Covering all species from yeast to humans, Genes in Conflict is the first book to tell the story of selfish genetic elements, those continually appearing stretches of DNA that…
I am adopted. For most of my life, I didn’t identify as adopted. I shoved that away because of the shame I felt about being adopted and not truly fitting into my family. But then two things happened: I had my own biological children, the only two people I know to date to whom I am biologically related, and then shortly after my second daughter was born, my older sister, also an adoptee, died of a drug overdose. These sequential births and death put my life on a new trajectory, and I started writing, out of grief, the history of adoption and motherhood in America.
I grew up thinking that being adopted didn’t matter. I was wrong. This book is my journey uncovering the significance and true history of adoption practices in America. Now, in the wake of the U.S. Supreme Court’s overturning of Roe v. Wade, the renewed debate over women’s reproductive rights places an even greater emphasis on adoption. As a mother, historian, and adoptee, I am uniquely qualified to uncover the policies and practices of adoption.
The history of adoption, reframed through the voices of adoptees like me, and mothers who have been forced to relinquish their babies, blows apart old narratives about adoption, exposing the fallacy that adoption is always good.
In this story, I reckon with the pain and unanswered questions of my own experience and explore broader issues surrounding adoption in the United States, including changing legal policies, sterilization, and compulsory relinquishment programs, forced assimilation of babies of color and Indigenous babies adopted into white families, and other liabilities affecting women, mothers, and children. Now is the moment we must all hear these stories.
Who Is a Worthy Mother?: An Intimate History of Adoption
Nearly every person in the United States is affected by adoption. Adoption practices are woven into the fabric of American society and reflect how our nation values human beings, particularly mothers. In the wake of the U.S. Supreme Court's overturning of Roe v. Wade, the renewed debate over women's reproductive rights places an even greater emphasis on adoption. As a mother, historian, and adoptee, Rebecca C. Wellington is uniquely qualified to uncover the policies and practices of adoption. Wellington's timely-and deeply researched-account amplifies previously marginalized voices and exposes the social and racial biases embedded in the United States' adoption industry.…
