Dark+and+White+moths

Moths are a type of insect similar to butterflies. A species of moth lived in a forest made up of a mixture of dark- and light-colored trees. Some of the moths were dark-colored and some were light-colored. The coloring of these moths is inherited from parent to offspring. The dark moths were hidden from predators on the dark trees, and the light moths were hidden on the light trees. When the light-colored trees were killed by a disease, the forest was suddenly made up almost entirely of dark-colored trees. Generations later, almost all the moths had the dark coloring. Which of the following gives a correct explanation?


 * 1) The light moths that survived did not mate and have offspring because they saw that their offspring would easily be seen and eaten by predators.
 * 2) The light moths that survived had dark offspring because the change in the environment caused the parents to have offspring that would do better in the changed environment.
 * 3) The light moths saw that the dark moths were less likely to be eaten by predators, so they made themselves dark as well.
 * 4) The dark moths were better hidden from predators, so more of them survived. Because dark parents outnumbered light parents, there were many more dark offspring than light offspring in the next generation.

==== Correct answer: D. In a population of light and dark moths, if the number of dark trees for the moths to hide in suddenly increases, the number of dark moths will increase in each generation because more dark moths will survive and reproduce than light moths. ==== ==== **Misconceptions**: Change occurs in the inherited characteristics of populations of organisms over time because organisms observe other more successful organisms and model their appearance or habits.(AAAS Project 2061, n.d.). ====


 * Example**: There were white bears and brown bears in the arctic.250 years later there are only white bears left.This happens due to the fact that the brown bears can't catch seals due to the fact that the seals can see them from a far ways.The brown bears die off and only white ones are left.

Organisms that do not fit into an environment will die, and the others will survive and reproduce.#evolution#
