....so the human race does not not have superior intelligence to the races of bivalves? And since, as has been argued on these threads ad nauseum, there is no real distinction between "macro" and "micro" evolution, where does that leave us? How is it that through evolution, all the races of human kind turn out to be ........exactly even? What are the odds of that?
Strawman. The only measurement of success in evolutionary terms is fitness. Surviving species are very successful in their particular niche.
Except they aren't different races. Humans are currently undergoing microevolutionary changes, such as the spread of heterozygous sickle-cell anemia or lactose tolerance. Heredity is precisely the mechanism that ensures the dominance of traits within a population.
"Uh...........If the individuals perish, the characteristics are not passed on."
Strawman. They weren't very fit in the first place then.
Last time I checked, bivalves were not a race.
What is "exactly even?" Homo Sapiens went through a genetic bottlenecking event sometime in the last 100K years, with the population reduced to a couple of thousand breeding individuals, so we're going to be fairly close genetically. Up to about 50K years ago, there were at least three human species on the planet (Homo Erectus, Homo Neanderthalensis and Homo Sapiens). If the Flores Man thing turns out to be another species then we're up to four (I doubt it will, though, but one must keep an open mind). Unfortunately, all Homo species had pretty much come to fill the same niche in each of their environments; as Homo Sapiens spread out he displaced the others who eventually went extinct.
Not that I expect you to actually assimilate the information in this post, but at least the lurkers will see it.
