> Nature doesn't "optimize" like that exactly. Exactly. A stronger venom doesn't only mean that the spider can kill prey more efficiently. It also means that those individuals with the stronger venom mutation have higher chances of breeding. They can kill more efficiently and faster and thus have higher chances to survive long enough to reproduce. In evolution the mutation that leads in the long term to higher chances of reproduction usually wins.
