Which of the following scenarios is the best example of evolution?

A A particular species of flowers in a meadow were pollinated by bees for several hundred years. Over time, fewer and fewer bees can be found in the meadow. Some hummingbirds are attracted to a few of the plant species with brightly colored flowers. Over time, more of the plant varieties now have brightly colored flowers.

B. A mouse is nearly caught in a mouse trap. The mouse learns through that experience to stay away from mouse traps and teaches her offspring to avoid mousetraps. Mice are no longer caught in mousetraps.

C. A tidal wave removes all of the grass on an island.

D. A population of mice lives in a forest. A species of tree is introduced which reduces the amounts of nuts available for the mice. There does not appear to be a change in the mice over time.

The Correct answer is option A

Reason -

The concept of evolution revolve around the fact that the change in a species occur over a period of time, usually through several generations and through the process of natural selection. It also states that the species are dependent on each other and do change gradually over time.

The above scenarios are not not fulfilled in any of the options other than A. Though in option B, there is a change in characteristics of mice not being trapped in mouse traps but it is something which is taught and not attained through natural selection.
