[leps-talk] genetic basis for species

[Charles Bordelon]

I tried to mention this phenomonon before.  The universe is an ever-changing
place.  Not only is  it expanding outwardly, but inwardly, as well...  There
are no domains to describe infinity...  The birder-collector argument seems
to be the one constant in this universe; and it is getting old... VERY
OLD...(And very wordy...)  The simplicity is beyond our comprehension...

I agree with Niklas that we are not likely to get much information at the
subspecific level from genetics for quite a while (probably most of our
lifetimes).

But it is also possible that subspecific differences are not genetic but
reflect environmental and epigenetic factors that influence size,
pigmentation,
etc.

Plants, of course, are particularly vulnerable to variation influenced by
environmental conditions, resulting in recognition of ecotypes rather than
subspecies. The polyphenism in butterflies is a good example of
environmentally
influenced variation, and the seasonal forms of some of our common
butterflies
vary much more than many subspecies, which creates a nightmarish situation
in
my mind.  This is spring, the time of the tiny Cabbage White.
