Basic knowledge about the rate and range of mutation is central to our understanding of numerous evolutionary processes that include maintaining sexual reproduction and rates of molecular evolution.

Morphological diversity is generated by a continually shifting balance between variation and constraint. As modern evolutionary biology takes advantage of an enormous wealth of genetic and genomic ...

Concerns about biodiversity tend to focus on the loss of species from ecosystems, but a new study suggests that the loss of variation within species can also have important ecological consequences.

Variation is the differences between individuals of the same species, caused by genetic and environmental factors. Surveys into variation give data that are continuous, which means to come in a range, ...

The rapid loss of variation within species is a hidden biodiversity crisis, according to a new study looking at how this variation supports essential ecological functions and the benefits nature ...

Embracing difference is vital for our success as a species, but it places extra demands on the brain. Here’s how to get better at it Most people enjoy variety. We like to eat different foods from meal ...
