Yesterday was not the usual. And yes, I seem to have survived the medical procedures, at least thus far. Not sure my mental faculties are all that I should like them to be, but the aftereffects thus far are more the result of medications than procedure.
This leads me to contemplate an article [Link] I found about work from U Arizona. This work indicates that the success of modern homo sapiens is largely the result of miscegenation with other species of humans. And, yes, I know I have commented on this numerous times previously.
Anyway, what makes this cognitively attractive is not that it occurred, such is a matter of blatancy given recent efforts in genome mapping, but rather how it came about. The recorded history of humanity since around 500 BCE is replete with all sorts of proscription of miscegenation. In that paradigm, miscegenation is not reproductive activity between species, but between geographic and ethnic groups. When I was a bairn growing up in the old confederacy pink humans were not supposed to have reproductive relations with other shades of humans, or even with pink humans who were not denizens of the old confederacy.
That taboo is somewhat relaxed these days although not actually eradicated, hence the question of how did those ancient humans have the smarts to reproduce with different humans? Could it be that these attitudes towards miscegenation are an artifact of age and that it has only been since the invention of writing and civilization and such that enough people have lived long enough for these attitudes to emerge?
