Question

Birds in a desert climate survive on soft parts of cactus. Scientists observed that during a drought, manyof the birds died. The ones that survived had larger beaks and were able to crack open and eat hardseeds that would ordinarily not be used. What trait would you expect to see in the next generation?

Answer 1

Larger beaks. This question refers back to Darwin's theory of Natural Selection. "Survival of the fittest" if the birds that had small beaks all died, the only birds that would be left would be the ones with large beaks.
