>If evolution doesn’t happen, how come bacteria are now resistant to almost all types of penicillin, to the point we are in very real danger of “super bug” forms of e coli and strep?
Ah, and here’s something interesting: medics are finding out that these “superbugs” tend to be susceptible to ‘inferior’ antibiotics which the “normal” variety of the bacteria.
>Nor the lactose tolerance mutation that allowed middle easterners to move into central Europe with their cows and highly nutritious milk and suplant the non lactose tolerant population that was there before 6 to 9,000 years ago.
So, the equivalent is that if Americans with their superior farming techniques moved to some war-torn African state and displaced/supplanted the local population because we weren’t starving to death [and we had the will/means to protect ourselves] that would be proof of evolution?
Having the will and means to defend oneself is not the same thing as a genetic change that enables one to survive better on available resources. Infants are born with the ability to produce an enzyme called lactase which enables them to metabolize the lactose (sugar) in their mother’s milk. As they get older they lose the capacity to produce lactase enzyme and can no longer consume milk without digestive problems.
However, a new mutation occurred in someone which enabled them to produce lactase into adulthood. Thus they could consume nutritious milk that others could not. Their children when inheriting this gene also had a survival advantage and passed the gene on to additional offspring. Eventually there was a large enough group to go migrating into Europe where their ability to drink milk year round gave them a survival advantage. Whether warfare was involved is a separate matter. I am talking biology, not behavior.
