It's the same with populations and species. Species are out there competing with others in a real world of limited resources. They cannot survive as disembodied attributes. What's more, the ecologies of which they form a part have an alarming tendency to change abruptly. If your habitat is...
Finally, we have to bear in mind how distinctive new species originate. We don't understand everything about how this happens, but we do know that in large interbreeding populations, it is extremely difficult, if not impossible, for new genetic variants to become established. If any meaningful innovations are to...
You can guess where this argument is heading. During the Ice Ages, when our own species emerged, human populations were small and scattered and were continuously disrupted by climatic fluctuations. Conditions were ideal for genetic innovation. Today, however, the human population is 6 billion and mushrooming and increasingly densely distributed...
The upshot is that after a period of diversification, Homo sapiens is in a mode of reintegration, as witness the fact that the boundaries between the former geographical variants of our species are becoming increasingly blurred. If present trends continue, those boundaries will become blurrier still. Amid all this, the...
This being the case, all we can do is hope that things stay pretty much the way they are--which is both good and bad. The bad news is that we will forever remain the willful, capricious, appalling creatures that we have been ever since our species emerged during the...
