Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Hummingbirds have a beak just the right length to reach the nectar in a cardinal flower and as they feed their foreheads bump into the pollen structure. Cardinal flowers are red which hummingbirds can see but bees can’t. Cardinal flower’s pollen structure is just the right length for the hummingbird to pick up pollen as it feeds
A
Convergent
B
Divergent
C
Coevolution
Explanation: 

Detailed explanation-1: -1. hummingbirds have a beak just the right length to reach the nectar in a cardinal flower and as they feed, they touch the pollen structure, transferring pollen from one flower to another. 2. This process of hummingbirds transferring pollen from one flower to another is known as coevolution.

Detailed explanation-2: -The Galapagos finches evolved through natural selection from a common ancestor into a wide variety of different looking species with different kinds of beaks.

Detailed explanation-3: -The term coevolution is used to describe cases where two (or more) species reciprocally affect each other’s evolution.

Detailed explanation-4: -A kit fox lives in the desert and has large ears with greater surface area that keep the fox from getting overheated. The red fox lives in the forest and has a red coat that keeps it camouflaged.

Detailed explanation-5: -Two species occupying a similar habitat may exhibit common physical traits; if these species come from different biological ancestors yet still have much in common, their similarities may be the result of convergent evolution.
