Species can split into two when freewheeling gene exchange is no longer possible, a barrier Overdrive appears to build.

A. From "Gene could drive species separation"

"A newly identified gene in fruit flies may drive the creation of new species, revealing how internal genetic environments may be just as important as external factors when it comes to speciation. The new work lends evidence to a hotly debated idea in evolutionary biology.

“Conventionally, evolutionary biologists thought that speciation involved adaptation to the external environment, but these results suggest that adaptation to the internal genomic environment also sometimes plays a role,”
