This is kinda backwards. Biodiversity is a result of random mutation over millions of years. Evolution is the result of selective pressures "choosing" from that diversity. It doesn't create or provide biodiversity, it depends on it, so biodiversity should be the one providing crabs. Evolution just thinks they're neat.

Evolutionary pressures form new organisms, which feed biodiversity. More crabs aren't as diverse as that sounds.
