Natural Slection
Pocket Mice
Scientists identify the molecular differences that underlie adaptive coat color variation in the natural population of rock pocket mice, Chaetodipus Intermedius. Rock pocket mice are normally light-colored and live on light-colored rocks. However, colonies of dark (melanic) mice are present on dark lava, which defends against avian and rodent predators.

Individuals change color to blend in with the environment. In the area where they live, there is dark lava rock. They have a genetic mutation that causes the color of their fur.
Woodworms
Woodworms have been dyed in a number of quantities. Since we were looking for them when they were on the grass, it was harder to spot green woodworms as they were camouflaged in the grass and their genetic mutation caused them to have that trait. As with the other colors, they were easier to find because they couldn't mix in the grass. Since the woodworms had five subspecies, all of them with different colors, the green ones were the hardest to find. This will later raise the population of green woodworms so they would multiply while the other woodworms of a different color would be extinct.
Colors: Red, Yellow, Blue, Green, and Teal

This will offer the black Moths an edge as they would later multiply, and earlier the number of the black moths would rise and the light moths would decline.
Before the Trees had darkened, the light moths were able to thrive, but after the factories had darkened the trees, some moths had turned black and some had remained light. Because of this, light moths couldn't survive because they weren't camouflaged.
The countryside between London and Manchester was polluted with soot from the new coal-fired plants. Some of the light-bodied moths died of sulfur dioxide emissions, and the forests were darkened.

More than half of the female elephants have been bred without tusks. Poachers hunting elephant ivory may have found their match in one of the strongest powers of nature, natural selection. At least in two national parks in Africa, where poaching has become a big concern, most female elephants are now born without tusks. This just doesn't bother female elephants as much as they don't use their tusks. Male elephants use their tusks to battle for other females and to dig for minerals.
