The study of how genetic variation leads to evolutionary change is called evolutionary genetics.
It includes topics such as the evolution of genome structure, the genetic basis of speciation and adaptation, and genetic change in response to selection within populations.
Aim:
The aim is to understand the diversity of life from a genetic perspective, using DNA sequences to study population history and evolution.
Increasingly, this involves studies of complete genomes, offering exciting new opportunities to apply a wealth of data in order to address long-standing questions in evolutionary biology.
