• gradual evolution

• reproductive isolation

A species of bird thrived in a very warm environment, but over time their environment experienced a rapid change to a colder climate. This change in climate caused a decrease in the birds with fewer feathers. What is the reasoning for this?

• Birds that had fewer feathers were too hot before and could only survive in the new climate

• Birds with fewer feathers were best suited for the new environment

• Birds with more feathers were best suited for the new environment

• Birds with more feathers were too cold before and could only survive in the old climate

How would mimicry be a useful adaptation?

• organism could be mistaken and avoided by a predator

• organism could blend into the environment to obtain food

• Organisms could acquire traits based on their environment

• organisms could be easily spooted by predators
