New research shows male lizards are more likely than females to be attacked by predators because the bright colours they need to attract a mate also make them more conspicuous to birds.
Researchers have observed the process of evolution by natural selection at work in robots, by constructing a ‘mother’ robot that can design, build and test its own ‘children’, and then use the results to improve the performance of the next generation, without relying on computer simulation or human intervention.
A new study of 565 million-year-old fossils has identified how some of the first complex organisms on Earth – possibly some of the first animals to exist – reproduced, revealing the origins of our modern marine environment.
A new book tells, for the first time in full, the extraordinary story of drawings of embryos initially published in 1868. The artist was accused of fraud – but, copied and recopied, his images gained iconic status as evidence of evolution.
Past research shows men find female faces more attractive at peak fertility. A new study shows an increased redness of women’s face skin at the most fertile point of ovulatory cycle, but just under the threshold for detectability, ruling out skin colouration as a driver of the attractiveness effect.
A newly-identified species of spike-covered worm with legs, which lived 500 million years ago, was one of the first animals on Earth to develop armour for protection.
Newly-discovered ‘ring of teeth’ helps determine what common ancestor of moulting animals looked like24 Jun 2015
A new analysis of one of the most bizarre-looking fossils ever discovered has definitively sorted its head from its tail, and turned up a previously unknown ring of teeth, which could help answer some of the questions around the early development of moulting animals.
First evidence for a species difference in the innate predisposition for tool use in our closest evolutionary cousins could provide insight into how humans became the ultimate tool-using ape.
