Birth of New Species Requires Very Few Genetic Changes
Only a few genetic changes are needed to spur the evolution of new species — even if the original populations are still in contact and exchanging genes. Once started, however, evolutionary divergence evolves rapidly, ultimately leading to fully genetically isolated species, report scientists from the Univ. of Chicago in Cell Reports.
“Speciation is one of the most fundamental evolutionary processes, but there are still aspects that we do not fully understand, such as how the genome changes as one species splits into two,” says Marcus Kronforst, Neubauer Family assistant professor of ecology and evolution, and lead author of the study.
