Hummingbirds have a beak just the right length to reach the nectar in the long cardinal flower. The cardinal flower’s pollen tube is just the right length for the hummingbird to pick up pollen as it feeds.

Humans cross pollinate different fruits and vegetables and other plants to yield the results that they want or to create new species. For example, humans have done this with corn (see above). This is an example of

Islands serve as sites of _____________________ due to being isolated. For example, on the island of Hawaii, the honeycreepers have evolved into different species depending on their diet. The ‘I’iwi has a long curved beak for sipping nectar out of flowers.
