Standard creationist disinformation.

The science behind evolutionary biology is based on observation, not
value judgements. It's no more "racist" than gravity, germ theory or
the periodic table of the elements.

Quite the contrary, evolution demonstrates that there is no rational
basis for racism. "Genetic studies show that humans are remarkably
homogeneous genetically, so all humans are only one biological race.
Evolution does not teach racism; it teaches the very opposite."
http://www.talkorigins.org/indexcc/CA/CA005.html

That's a specious argument.

Bill is referring to races, or subspecies, within Homo Sapiens. Many
species probably started off as a subspecies of some other species, and
eventually became sufficiently different genetically that interbreeding
became impossible.

Except that there are no subspecies within the human race. With the
"internationalization" of travel these days, unless we were to become
reproductively isolated in the future by some catastrophic event,
there never will be.

Didn't such factors drive the evolution of genus Homo, from Homo Erectus
to Homo Sapiens?

Since there is only one species of Homo at the moment, the point is
moot at the present time.

So in the far future, won't there evolve a Homo Futuristicus someday, a
subspecies of genus Homo that is as advanced beyond Homo Sapiens as Homo
Sapiens is beyond Homo Erectus? And could Homo Futuristicus drive Homo
Sapiens to extinction?

See above re: reproductive isolation.

The answer is NO--up till now--because Homo Sapiens proved to be smart
enough to stop evolution in its tracks. We don't allow the sick and
injured to die; we devised medical treatments. If people are starving,
we find ways to feed them rather than let them die. And there are no
more isolated places on Earth where a subpopulation of humans could
evolve free of interference. Our civilization has made a conscious
decision to stop natural selection, and hence to stop evolution.

No, our species is still evolving. Changes in allele frequencies
within a population over time has not ceased.

That could change, if genetic engineering makes it possible to indeed
improve the species. But that would come by artificial selection, not
natural selection.

I would say "change" the species rather than "improve." Improvement
is a value judgement. But yes, that would be artificial selection as
far as we're concerned.
