What do you think it should be?

anonymous · Answer

A or c im not sure

abhisar · Answer

C is not correct because then there would be no selection. We just answered your wildebeest question. Can you recall, some of them were better adapted and had greater probability of survival?

Natural selection only takes place when some of the traits are improved in an individual.
