Peacocks attract their mates using their colorful tail plumes. They have isolated themselves from other bird species via

• Geographic Isolation

• Temporal Isolation

• Behavioral Isolation

Chimpanzee gametes and human gametes have the same number of chromosomes, but cannot come together to produce viable embryos. This is an example of

What is a species? 

• A group of organisms that can mate with each other and produce fertile offspring. 
• A group of organisms that can mate and produce offspring even if those offspring are infertile.
• A group of organisms that genetically are very different from each other.
