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.

Australian researchers have uncovered how a particular strain of a diarrhea-causing parasite managed to infect more animal species, offering new insights into how parasitic infections emerge and ...

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

An evolution experiment involving beetles has provided the first direct evidence that caring for offspring results in the accumulation of more genetic mutations in a population. Some of the mutations ...
