One of the major premises of Evolution by Natural selection is that

• all the members of a population are identical in every way

• individuals of the same species have exactly the same genes

• variety in size, color, speed and intelligence make some individuals in a species more likely to survive and reproduce

• smaller animals are more likely to die and not reproduce because they are slower

The process of two species changing genetically in response to long-term interactions with each other is

• artificial selection

• coevolution

• selective breeding

• resistance

When insects eating crops are no longer killed by an insecticide designed to kill them it represents

• adaptation

• coevolution

• evolution of resistance

• natural selection

Which of the following organisms is not the result of artificial selection
