A new study compares the accumulation of mutations across many animal species and has shed new light on decades-old questions about the role of these genetic changes in ageing and cancer. Researchers ...

Genes are short sections of DNA that determine an animal’s traits—everything from coat color and claw strength to body shape and health. But sometimes, these genes mutate. And while the word itself ...

The rates of germline mutations — genetic changes passed from parents to their offspring — have been estimated for 68 vertebrate animal species using a method involving mother–father–offspring trios.

In the children’s game telephone, a whispered phrase like “I ate a pear” can quickly become “I hate bears” as it moves down a line of players. As genes are passed down from parents to offspring, they ...
