Which is why I think there will be a divergence between an upper and lower class of human being.
While the lower class propagate incessantly, they do not inbue their young with knowledge. In modern times, knowledge is power. Brain is the new
brawn.
We may have evolved to our physically supreme state (or rather physical evolution may have been halted by modern medicine), but mental evolution
continues.

Your examples are very limited. In your haste to discredit Prof Jones, you didnt even mention that the adaptation against malaria is not an entirely
desired genotype... it is a disease. Literally.
Sickle cell anaemia offers protection against malaria, at the cost of impeding the person's physical capabilities by 15% or more. Additionally, if
there is a recombination of two sickle cell positive people, their child's blood will be 50% oxygen deficient.
Additionally there aren't any people immune to AIDS in Africa. The only people on earth immune to AIDS are 10% of Scandinavians and Iranians, who
have residual immunity from a resistant CD4 adaptation which was originally to combat the Plague. AIDS uses the CD4 pathway and so cannot harm these
individuals.
You also state that it is the (to put it mildly) more promiscous who affect the future of evolution by increasing the frequency of their genome in the
gene pool. Yes, this is true, but quantity does not equate to quality. A promiscous woman is hardly likely to be intelligent, and neither are her
offspring.
The forward vanguard of evolution will not be those that developing passing resistance to malaria or other nominal physical threats. The most evolved
will be those who are the offspring of intelligent, successful people, who in turn marry people of the same disposition.
