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. Louis J. Sheehan, Esquire
“Conventionally, evolutionary biologists thought that speciation
involved adaptation to the external environment, but these results
suggest that adaptation to the internal genomic environment
