In Darwin’s theory of evolution by natural selection, the key phrase is “survival of the fittest”: those organisms that are best fit to carry out the tasks of living in their world are the ones that survive. But they won’t live forever — they must have offspring that inherit the traits that made them fit in order for evolution to proceed.
This conceptual framework is fine for understanding the evolution of traits that affect survival and numbers of offspring. But what about the rules of inheritance themselves? These rules are also organismal traits, although they need not have any effect on how well the parents survive or how many offspring they have. In fact, the rules of inheritance say what the offspring are, rather than how many there are. Classical mathematical models of evolution have little to say about the evolution of these rules. How, then, can “survival of the fittest” shape the rules of inheritance?

Evolutionary Causation: Biological and Philosophical Reflections
“Evolutionary Causation: Biological and Philosophical Reflections“, edited by Tobias Uller and Kevin Laland, has just been released through the MIT Press. One of the major publications from the EES project, it is a tightly-integrated array of essays from biologists and philosophers on the causal structure of evolution. You can read the preview on Google Books and order the book through major outlets such as Amazon, Powell’s, etc.
In the next few blog posts, we will explore some of the major themes presented in the book, such as developmental bias & plasticity, niche construction, major transitions in individuality, etc. Today, we interviewed Tobias Uller, lead co-editor, about the book and its backstory. We also asked him to suggest various ways to approach the book.
Early Career Spotlight with Illiam Jackson
Illiam Jackson just wrapped up his work at Tobias Uller’s lab (Lund) and is moving on to great things. We talked to Illiam about himself, his work, and papers he liked under the EES project.

Early Career Spotlight with Thomas Oudman
The “Does Evolutionary Theory Need a Rethink?” Debate: A Backstory
In October 2014, Nature magazine published “Does evolutionary theory need a rethink?”, an exchange in back-to-back articles between advocates of an ‘extended evolutionary synthesis’ and more traditionally minded researchers. The exchange provoked considerable discussion across many academic fields, which continues to this day. Recently, on Twitter, a question was raised concerning the origin of this piece. Who initiated this "debate?" Was there an actual dialogue between the sides prior to publication?
StuFest- Celebrating Stuart Kauffman’s 80th Birthday
This year we celebrate Stuart Kauffman's 80th birthday. Kauffman was one of the early proponents of the view that the complexity we see in biological systems is not necessarily a consequence of natural selection alone, but could result just as well from spontaneous self-organization.
The Role of Mobile Genetic Elements in Evolution and Development
A new study in Evolution Letters suggests that transposable elements are important for both developmental processes and evolutionary diversification in snakes and lizards. Author Dr Nathalie Feiner explains her findings in our latest blog.
Evolution Evolving: Process, Mechanism and Theory
Last week, 200 delegates took part in the Evolution Evolving conference at Churchill College, Cambridge, UK. The conference was one of its kind – bringing together senior and junior academics from many different fields to encourage discussions across empirical and theoretical biology, philosophy and history of science, computer science, and anthropology. The atmosphere buzzed with enthusiasm and excitement. The title of the meeting – Evolution Evolving – captures that the evolutionary process itself evolves over time, an idea encapsulated in the concept of ‘evolvability’, which was one focus of the meeting. But it also highlights that evolutionary biology itself evolves, as it implements insights and tools from many other sciences, as well as the philosophy of science.
