Evolution is much slower. Takes place over the course of a minimum of tens of thousands of years and is heavily influenced by natural stressors.
If you ever see 2 animals that don't typically kill one another in the wild, even though it seems like they should (hippos and crocs for example), it usually means there were tens of thousands or even millions of years where, in this case, the instinct to eat proto-hippos got millions of proto-crocs killed, and the hippos that couldn't kill crocs all died off.
So which ones lived? The hippos that could fuck a croc up, and the crocs that steer clear of hippos are more likely to pass their genes.

Genetic defect is just another word for evolution.
