Question

Susan makes a claim that humans do not evolve because we adapt to situations by changing our technology, not ourselves. Which piece of evidence contradicts this idea

Answer 1

caucasians can digest dairy products because ancestors like 10.000 years ago didn't stop drinking milk. ages of diarrhea all over the board. thank you, ancestors! also, putting a fur coat on your skin makes your own fur kinda redundant.

apart from that, susan's statement is comparing apples and oranges. evolution happens in a whole different timeframe than technology. changes in DNA take many many generations worth of time, while the spread of a new technology usually takes less than one generation.

it is worth mentioning, though, that evolution can also happen on a social level. if he who influences the gene pool of the next generation most is especially funny/intelligent/hairless (and these attributes are thought of as attractive for a few generations), then the population will evolve in that direction, even though none of these traits actually benefit the survival rate of that person.
