In theoretical discussions of the potential effects of collective interactions in such biological systems, statistical physics principles and methodologies have been applied. In order to enhance their capacity for collective computation, it has been suggested that such collective systems should function close to a phase transition, specifically a (pseudo-)critical point. This paper will [...]

Experimental mosaic brain evolution improves main executive function abilities in the guppy

Executive functions are a set of cognitive control processes required for optimizing goal- directed behaviour. Despite more than two centuries of research on executive functions, both in humans and nonhuman animal species, there is still a knowledge gap of what constitutes the mechanistic basis of evolutionary variation in executive function abilities. Here we show experimentally that changes in [...]

The urgent need for medical treatments of alcohol use disorders has motivated the search for novel molecular targets of alcohol response. Most studies exploit the strengths of lab animals without considering how these and other species may have adapted to respond to alcohol in an ecological context. Here, we provide an evolutionary perspective on the molecular and genetic underpinnings of alcohol [...]

Re-examining extreme sleep duration in bats: implications for sleep phylogeny, ecology and function

Christian David Harding, Yossi Yovel, Talya Hackett, et al.

Bats are quoted as sleeping for up to 20 hours a day, an example of extreme sleep duration amongst mammals. Given that duration is one of the primary metrics featured in comparative studies of sleep, it is important that determinations of species-specific sleep duration are well founded. Here, we summarise the evidence for the characterisation of bats as extreme sleepers and discuss whether it [...]
