Palaeontology has gone high-tech: no more wax and plaster-cast models. Instead, 3D data from computed tomography (CT) scans is overturning long-held views of how the earliest land animals moved. Research…
In the last few years, several laboratory studies have shown that, to some extent, we can tell whether someone is gay or straight, just by glimpsing their face. When asked to categorise male and female…
When it comes to selecting a mate, females are traditionally thought of as the choosy sex; males, meanwhile, aren’t thought to be particularly picky. This makes sense for many species – the sex that invests…
Australian researchers have provided the first support for a 60-year-old evolution theory - that species with multiple colours in the same population evolve into new species faster than those with one…
The penis. It comes in so many different shapes and sizes … and that’s just in humans. As you would imagine, different species have very different penises. The males in most mammal species, including cats…
People often ask me whether natural selection continues to operate on modern humans in industrialised societies, even though technology has liberated so many from hunger and early death. My answer is always…
A report published today in Nature by Yohannes Hailie-Selassie and co-workers outlines the importance to our evolutionary story of some very ancient foot bones discovered recently in the Rift Valley of…
The fossilised remains of three people found in southwest China could belong to an unknown species that was related to modern humans and survived until the end of the Ice Age 11,000 years ago. The discovery…
The origin of the human species remains one of the most fascinating and difficult topics of modern science. One of the main reasons for this is a continuing lack of agreement about how we should define…
Few of us consider that having sex could result in a violent, instantaneous death. But in nature, where sex and violence are often two sides of the same coin, many animals are routinely subjected to such…
