The question of why human beings have virtually no body hair – as discussed yesterday on The Conversation – has puzzled evolutionary theorists since Darwin’s Descent of Man (1871). It’s puzzling because…

Candida tropicalis cells, once thought to be asexual, have been discovered as being capable of mating sexually. Scientists…
The debate regarding how mitochondria first entered our cells has been reignited, with research from the University of Sydney…
Writing almost 140 years ago in his book Naturalist in Nicaragua, the European naturalist Thomas Belt engaged in a lively debate about why certain breeds of dogs in tropical America were hairless. The…
Humans are not capable of further developing our cognitive function, according to two British pyschologists. The researchers…
Two distinct populations of rainbow trout – one in Alaska, the other in Idaho – share a genetic trait that could have huge…
We currently face a biodiversity and extinction crisis as human population pressures and climate change combine to push our natural environments to the limit. Because our urban and agricultural activities…
Genetic variation persists through generations, rather than being bred out in an evolution towards a “perfect type”, shows…
SEVEN BILLION PEOPLE: I had better write fast. Sometime between my deadline to submit this story and the time it goes live, the estimated world population will exceed 7 billion for the first time ever…
The mere presence of a predator can cause enough stress to kill a dragonfly, even when that predator can’t actually get at…
Multiple mating - or polyandry - is beneficial for females, according to an experimental evolutionary study. In an article…
My intention with this article is to give an intuitive and non-technical introduction to the field of evolutionary algorithms, particularly with regards to optimisation. If I get you interested, I think…
Groups of male dolphins who put aside their sexual competitiveness and form alliances with each other to seek out and reproduce…
How have humans and mice changed since we diverged about 75 million years ago from a small, furry common ancestor? Apart from the obvious, of course. As a starting point, it’s worth noting there’s nothing…
The widely believed theory that cycad plants, or “dinosaur plants”, are living fossils has been debunked. Using genetic analyses…
Recent genome sequencing of different species including the platypus has sought to answer the question of how genes have…

Why do female Eclectus parrots kill their sons as soon as they hatch? While humans sometimes “sex select” their babies, no…

Research published in this month’s BioEssays confirms something many of us have always known: women have stronger immune systems than men. We fight off infections more readily, are less likely to develop…
