A sweeping analysis of thousands of animal genomes suggests that chromosomes do not evolve randomly but instead follow a limited number of irreversible “evolutionary highways.” These one-way genetic ...

A series of whole genome and gene duplication events that go back hundreds of millions of years have laid the foundations for tissue-specific gene expression, according to a new study. The 'copy-paste ...

The Cambrian explosion may have been fueled by poop. The first animals on Earth emerged about 600 million years ago, and 60 million years later, those simple early animals evolved in wildly different ...

Animals from completely different branches of the tree of life, such as insects, worms and vertebrates, independently evolved similar genetic solutions to survive on land, according to a new study ...

From butterflies to blue whales, corals and worms, Earth is home to an incredible diversity of animals. How all of these animals evolved from earlier, simpler ancestors is one of the most exciting ...
