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

The piece of evidence that contradicts this is the loss of our double eyelids. A few million years ago we had double eyelids but we no longer needed anymore so it mutated out.

Answer 2

The size of our brains has increased since we became tools users.

While the technology improved, our brains also evolved to take in all that new knowledge. New information is needed to be saved so our brain had to increase in size to hold all that.

This is the piece of evidence that contradicts susan's argument because humans had small brains and evolved to have larger brains, while the techology is also changing.
