Question

Billy thinks evolution is slow and continuous. He believes in gradualism,punctuated equilibrium, or convergent evolution.

Answer 1

If Billy believes evolution is slow and continuous, then he also believes in gradualism. Gradualism refers to the type of evolution that takes a long time to occur - as the name itself say, it all happens gradually, one segment at a time. This process is very slow, and cannot happen overnight, which is something Billy understands well.
