When an organism of a species is born with a variation in a trait that gives it an advantage in its environment, we call that trait an adaptation.

• true
• false

When an organism of a species has an adaptation, it will compete for resources better, survive longer and pass that adaptation on to it's offspring. This process is called

• evolution by natural selection
• artificial selection
• inbreeding
• outbreeding
