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

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

Humans have become one of the world's greatest evolutionary forces. To survive our cities, animals from urban foxes to ...

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 ...

When the environment changes dramatically, animals from mollusks to crows can make big changes in their behavior that enable them to survive. For example, marmots and ground squirrels in California ...

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 ...
