Which of these is an example of a key innovation?   A caterpillar of a butterfly species provides honey to an ant colony in order to receive protection and care.   A founding population of honeycreepers evolves beaks capable of cracking the seed of a tree species in their new habitat.   A new flower color morph arises in a plant population, but an associated pollinator does not distinguish flowers by color.   Co-occurring diploid species of wheat and goatgrass hybridize to form a viable tetraploid offspring that can no longer breed with its parents.

Evolutionary adaptations

Evolutionary adaptation is the process through which organisms adapt or adjust to their surroundings to increase the chances of survival, mating, and reproduction. An organism's behavior, physiology, and structure are adjusted or changed to make it more suited to its environment.
