Re: Chippie invasion, Chickadee hybrids, Checkered skippers



"But just as likely, this could represent a stable hybrid zone that
will maintain a fuzzy boundary between the two forms for a long, long
time.
If this last scenario is the case, then they could maintain their basic
genetic integrity, but also have the capability of exchanging some genes,
especially if that trait is a useful one, under positive selection."
Hi folks. I read something about Darwin's finches a few years ago, and
there was evidence that a few "good" closely related species, during
times of environmental stress, hybridizing. This seemed in response to
the stressors, and may have been of some selective advantage to the
progeny.
Was in Marion yesterday, at the Wal-Mart, and saw an Osprey patrolling
the Catawba River.
