Okay, then why did humans continue to evolve if there was no impetus to do so?.......Humans continue to evolve and cockroaches continue to evolve. As long as allele frequencies change, evolution is taking place. There are a number of factors currently driving evolution in both humans and cockroaches: DNA mutation, the fact that not all individuals reproduce succesfully (aka natural selection), gene flow, and genetic drift.

Humans continue to evolve and cockroaches continue to evolve.
Says who? The Darwinian approach does not require further evolution. How do you define evolution? Are you saying that a revived 50,000 year old cockroach would not be able to mate and produce fertile offspring with present day cockroach? Do you consider minor variations within a species evolution?
