Answer to Question 1

On land, animals had to worry about reproduction, desiccation, gravity, and the extraction of oxygen
from the atmosphere.



Answer to Question 2

The development of predators had a major impact because organisms that had previously not needed
defense mechanisms either developed defense systems or suffered great population losses.
