The discovery of a 500 million-year-old fossilised brain has helped identify a point of crucial transformation in early animals, and answered some of the questions about how heads first evolved.
A new study of teeth belonging to a particularly phallic-looking creature has led to the compilation of a prehistoric ‘dentist’s handbook’ which may aid in the identification of previously unrecognised specimens from the Cambrian period, 500 million years ago.
The first 3D reconstruction of the skull of a 360 million-year-old near-ancestor of land vertebrates has been created by scientists.
Many animals, including humans, acquired essential ‘foreign’ genes from microorganisms co-habiting their environment in ancient times, according to research published in the open access journal Genome Biology. The study challenges the conventional view that animal evolution relies solely on genes passed down through ancestral lines and suggests that, at least in some lineages, the process is still ongoing.
The origins of Darwin’s theory of evolution – including the pages where he first coins and commits to paper the term ‘natural selection’ – are being made freely available online today in one of the most significant releases of Darwin material in history.
An international team of researchers has shown that it may be possible to improve the effectiveness of the seasonal flu vaccine by ‘pre-empting’ the evolution of the influenza virus.
Females protect offspring from infanticide by forcing males to compete through sperm instead of violence13 Nov 2014
Latest research shows the females of some mammal species will have many mates to ensure unclear paternity, so that males can’t resort to killing their rival’s offspring for fear of killing their own. This forces males to evolve to compete through sperm quantity, leading to ever-larger testicles. Scientists find that as testis size increases, infanticide disappears.
Millennia-old genetic variant that once provided advantages for survival in cold climates increases risk of hypoglycemia and infant mortality.
New research shows that chimpanzees search for the right tools from a key plant species when preparing to ‘ant dip’ - a crafty technique enabling them to feast on army ants without getting bitten. The study shows that army ants are not a poor substitute for preferred foods, but a staple part of chimpanzee diets.
