Niche microdifferentiation

From Wikipedia, the free encyclopedia

Niche Microdifferentiation is an example of how evolutionary variation in genes is maintained. It simply means that an advantage for one animal in one area is not an advantage for another animal in a diffenret location. For example, a moth which is white and lives in an area where tree bark is stripped and tree color is white will more easily survive than a white moth in a different location where trees are moss-covered and green.
