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?

The adaptation is a type of evolution.

In biology, the evolution is described as the gradual changes taking place in an organism, which can be incorporated into the genome and passed from one generation to another.

The adaptation to the changing environment leads to changes in the physiological function. So, in Susan's statement ' we adapt to situation' represent the modifications are taking place, which means evolution is taking place. Hence, this statement is contradictory.

your answer is "the 1950's"
