Question

Is there evidence of selection for defensive adaptations in mollusc populations exposed to predators?

A) The fossil record provides evidence that predator-prey interactions may have shaped the course of animal evolution.
B) Predators and prey are important selective agents on each other.
C) Unsuccessful predators cannot obtain food, while prey that are unsuccessful at resisting attack are eaten.

Answer 1

A) The fossil record provides evidence that predator-prey interactions may have shaped the course of animal evolution.

Step-by-step explanation:

For example, through evolution, periwinkle populations with a history of predation by crabs have become less vulnerable to crab predation.

The researchers' hypothesis was that southern periwinkle populations with a history of predation by crabs have become less vulnerable to crab predation through evolution.
