I stray from point if you dont consider other creatures evolution in any way helpful in understanding evolution as a whole I suppose. But I do see what you mean, obviously humans dont have the seperation required to cause similar reactions that I see in the boas and pythons. So let me think a bit...
How about selective breeding of our own species? Of course we do it, selecting mates we would easily get along with (of course, this is all succeptible to debate...because human copulation in no way HAS to involve "liking" one another as a person).
In the current day and age though...the debate that we are here to discuss...is a VERY iffy subject for many. Would it be hard to imagine that those believing in a creator would more easily get along with others who believe the same? And the evolutionists as well...
What if I said that recent studies have shown that a low level of serotonin and serotonin receptors are showing to be prevalent in those believing in religion...or claiming to have "religious experiences". Not a rule of thumb of course...but it is amazing how it appears to be MUCH more concentrated in the religious population. Would it then be a stretch to suggest that the trend would continue to build? Who knows what a long term effect this would have on a species...we know short term, low levels being directly linked to depression.
Adversely though, high levels arent any better it would seem. It has been linked to infant deaths...
Serotonin is also linked to how our brains process the information it recieves, and also effects what we THINK we see. The effects of being hypo' or hyper' in this respect are vast, and I could go on and on...but I see it as a REAL possibility that humans would select mates with similar traits...and beliefs...which could soon be shown to be further linked to our individual biology. In the long run, I wouldnt find it hard to imagine that if you skewed the species in 2 in which one degressed in serotonin production...and one gained more receptors, and serotonin levels...that it could potentially lead to 2 different species. Of course...this is a BIG if...I see the theoretical possibility...but as mentioned earlier...copulation has nothing at all to do with chemical biology other than maybe pheromones...and visual DNA evidence that we see that we consider of high value like good looks...
And this is one single chemical change mind you. I could not even begin to imagine what a slight chemical change in a population would cause, any chemical...I think it would be a good place to explore in this debate on where our species is headed, and likely the first place it WILL happen next.
(Mind you, you will find my posts generally only contain biological information...which I find the most intriquing, and the most important part of any related debate. I will leave the phylosophy of the same debates, and how our species could possibly reach separation again in the future, to others with a better understanding of the subject than I do)
