evolution

One of the most puzzling aspects of human behaviour is cooperation, in situations where backstabbing and selfishness would seem to be more rewarding. From the point of view of evolutionary theory, the very existence of altruism and cooperation appear mysterious.

Why do most of us stick to social rules? Game theory offers an explanation.

A new study suggests that monkeys have a basic grasp of probabilities.

Some uncomfortable problems in our understanding of life.

Geneticists find fascinating clues to the origin of life.

How many possible genetic relationships are there between a collection of different species? The answer is mind-bogglingly large.

Why evolution through natural selection is more than a mere "theory".

Where does our ability to do abstract maths come from? A new study sheds some fascinating light on the question.

People as well as animals are born with a sense for numbers. But is this inborn number sense related to mathematical ability? A new study suggests that it is.

Foraging ants have a hard life, embarking on long and arduous trips several times a day, until they drop dead from exhaustion. The trips are not just long, they also follow complex zig-zag paths. So how do ants manage to find their way back home? And how do they manage to do so along a straight line? Their secret lies in a little geometry.
