A new species of fish is introduced into a lake. The fish quickly takes over the lakes and evolves into several related species. This is an example of
Adaptive radiation
Sexual selection
Gene flow
Genetic drift
10.
A small population of 500 turtles on an island suddenly suffers a natural disaster leaving only 20 surviving turtles. Before the disaster, the turtles had shells with very different shell patterns. After the disaster, the shells all look very similar. What mechanism can best explain this reduction genetic variation?
Adaptive radiation
Genetic drift
Gene flow
Sexual selection

Who independently proposed the idea of natural selection and evolution at the same time as Darwin?
Kary Mullis
Peter and Rosemary Grant
Jean-Baptiste Lamarck
Alfred Russell Wallace
