• adaptation
• vestigial structure
• mutation

There is a population of bunnies. There are more bunnies there than will survive to reproduce. This describes which part of natural selection?

• overproduction

• genetic variation

• struggle to survive

• successful reproduction

This refers to how good an organism is at surviving and passing on their genes to further generations

• Fitness

• Stamina

• camoflage

• mutation

Camouflage

• A change in genes that results in a permanent trait.

• The production of extra babies where only a few will survive

• Fitness determined by an organisms ability to pass on genes

• Organism with the same appearance as their surroundings
