How do living beings fulfil the conditions for evolution by natural selection?

by Tobias Uller & Heikki Helanterä


Have you ever wondered why there is such intense disagreement over the evolutionary significance of niche construction? If so, you may be helped by a recent paper in the British Journal for the Philosophy of Science. The paper shows how contention arises from alternative assumptions regarding the causal independence of the processes that generate variation,

An unconventional place for unconventional science

by Wim Hordijk


Earlier this year, the inaugural workshop of the EES Project was held at the Konrad Lorenz Institute (KLI) in Austria. The KLI is a private and independent research institute with a focus on the development and evolution of biological and cultural complexity. Housed in a beautiful baroque building in the medieval town of Klosterneuburg, it offers a

A new evolutionary cause, and some implications

by Arlin Stoltzfus


In a critique of various “misconceptions” about evolution, Lynch (2007) states that evo-devo and other fields have not introduced any new population-genetic principles, nor overturned existing ones. That sounds a bit unfair. Advocates of evo-devo typically don’t offer novel population-genetic causes (and if they did, wouldn’t Lynch simply claim them on behalf of population genetics?).

Understanding the role of plasticity in evolution

by Alfredo Rago


No modern-day biologist doubts that the development, physiology and behaviour of living beings are influenced by their environment. Plasticity is everywhere and, in many instances, it has clearly been shaped by natural selection. Plastic responses can be sophisticated strategies for survival and reproduction, but the same could be said for every adaptive feature of living

Evolution Driven by Organismal Behavior

by Rui Diogo


In my latest book, Evolution Driven by Organismal Behavior, I present the theory of Organic Nonoptimal Constrained Evolution – or ONCE. It argues that evolution is mainly driven by the behavioral choices and persistence of organisms themselves, in a process in which Darwinian natural selection is a secondary – but still crucial – evolutionary player.

Could Planet of the Apes actually happen?

by Kevin N Laland


Following release of the blockbuster movie, biologist Kevin Laland asks ‘Why not?’   This week many of us will watch an army of retrovirus-modified apes wage brutal war against humanity. Unquestionably, chimpanzees on horseback, machine-gun-wielding gorillas and tutoring orangutans make spectacular theatre, but could it happen in reality? As people around the globe flock to

Conditional gene expression, developmental plasticity, and the diversification of horned beetles

by Armin P Moczek


Developmental plasticity is the ability of an organism to adjust aspects of its phenotype in response to environmental conditions (both internal and external). Plasticity is a well-studied phenomenon, and a growing number of studies implicate developmental plasticity in facilitating and shaping adaptive evolution. We used three horned beetle species to learn more about possible relationships

Epigenetic inheritance in evolution: an interview with Eva Jablonka

by Eva Jablonka & Katrina J Falkenberg


Eva Jablonka is a professor at The Cohn Institute for the History and Philosophy of Science and Ideas at Tel Aviv University, Israel. With Marion Lamb, she has been the most prominent longstanding champion of the importance of epigenetic inheritance in evolution and has published many papers and books on the topic. Katrina Falkenberg is

Deconstructing niche construction: A TVOL conversation between Gordon Burghardt and Kevin Laland

by Gordon M Burghardt & Kevin N Laland


The concept of niche construction stresses a dialectical relationship between organisms and their environments, rather than one being passively shaped by the other. It has deep roots in evolutionary thought but only now is resulting in a systematic research program as part of the Extended Evolutionary Synthesis (EES). Join Gordon Burghardt and Kevin Laland as

Linking micro- and macroevolution through studies of thermal plasticity in an old insect order thumbnail

Linking micro- and macroevolution through studies of thermal plasticity in an old insect order

by Stephen de Lisle


One major challenge in evolutionary biology is the apparent disparity between microevolution (evolution within populations over short timescales) and macroevolution (evolutionary divergence of lineages over millions of years). Studies of morphological evolution in deep time have revealed a pattern of stasis. In contrast, studies of contemporary populations and laboratory experiments have shown that evolution often
