A news article about a Nature study relating to sympatric speciation:
``This process, called "reinforcement", prevents closely
related species from interbreeding thus driving them further
apart genetically and promoting speciation.
Although scientists have speculated about this mechanism for
years, it has rarely been witnessed in nature.
"The phenomenon of reinforcement is one of the very few
mechanisms that has natural selection playing a role in
speciation," said Harvard co-author Nikolai Kandul. "It
might be very widespread but it is hard to find good
evidence of it."''
