" An adaptation is anything that gives an organism a better chance of survival. Structural and physiological adaptations are considered direct evidence of evolution. Most of the evidence to support evolution is indirect."
Direct Evidence
Camouflage-the disguising of military personnel, equipment, and installations by painting or covering them to make them blend in with their surroundings Mimicry-the close external resemblance of an animal or plant (or part of one) to another animal, plant, or inanimate object.
Charles Darwin-Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809-1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.
Natural Selection -"Survival of the fittest";when organisms with the strongest traits survive and reproduce
Directional Selection- when individuals at either end has higher fitness than individuals near the middle Disruptive Selection- when individuals at the upper and lower ends have higher fitness than individuals near the middle Stabilizing Selection- when individuals near the center of a curve has higher fitness than individuals at the either ends
