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 ...

Paleorex is back on Bored Panda with his detailed, science-based creatures, showing us how animals like big cats, birds, and reptiles might evolve in the future. In this article, we’re featuring even ...

A microorganism whose evolutionary roots can be traced to the era of the first multicellular animals may provide a glimpse of how single-celled organisms made a critical evolutionary leap. In ...

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 ...

A human, an octopus, and a coral could hardly look more different—yet deep inside their cells, their chromosomes still carry ...

Add Yahoo as a preferred source to see more of our stories on Google. Once upon a time, there were a bunch of one-celled microbes, swimming, eating, reproducing, doing all the things that a one-cell ...

By examining thousands of genomes along with fragments of ancient chromosomes, researchers uncovered the intricate journey of ...

In most narratives, the story of evolution is the story of organisms emerging from the ocean and eventually populating the land. But for some species, that evolution also involved a return trip.

Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) at the University of Oxford have uncovered a clue that may help to explain why the earliest evidence of complex ...

New research suggests ancient feces helped fuel marine life during the Cambrian Explosion.

To understand the origins of multicelled life, researchers are studying a motley assortment of simpler animal relatives. The commonalities they’re unearthing offer a trove of clues about our mutual ...
