Evolutionary biologists aim to form fundamental connections between microevolutionary processes and macroevolutionary patterns based on comparative datasets of population-level variation. In a new ...

Differences in the relative fitness of genomic variants are foundational, without these, neither natural selection nor adaption can exist. This research analyzed two microevolutionary forces, ...

Data on the chimpanzee genome help in detecting differential selection on individual genes, and in judging whether normal microevolutionary processes are sufficient to account for human origins. Over ...
