Adaptation and The Theory of Evolution by Natural Selection

1233 Words3 Pages

Adaptation and Natural Selection In Merriam-Webster Dictionary, adaptation is defined as a “modification of an organism or its parts that makes it more fit for existence under the conditions of its environment.” Also, natuaral selection is defined, “a natural process that results in the survival and reproductive success of individuals or groups best adjusted to their environment and that leads to the perpetuation of genetic qualities best suited to that particular environment.” As each species will have an evolution die off without an adaptation that assists in its survival, only those with the adaptation will be left. Thus the adaptations are kept within the gene pool for the next round of reproduction, eliminating the previous weakness. These adaptations become increasingly important due to the ever changing environment and local species. If any species does not adapt, they run the risk of being out-competed for food or being preyed upon and becoming extinct. Who is credited for this Theory's Development. “The theory of evolution by natural selection was proposed simultaneously by two different people: Charles Darwin and Alfred Wallace. Both men had studied the natural world extensively and made a number of observations that were critical to the development of the theory” (Natural History Museum). The Biosphere, “the largest biological system” (Chiras), is comprised of distinct regions within two categories: biomes and aquatic life zones. Biomes are divided by their physical characteristics, chemical composition, and the types of organisms present. The primary biomes are Tundra, Taiga, Temperate Deciduous forest, Temperate grassland, Dessert, Tropical Rain forest, and Altitudinal (Alpine Tundra).

Certain windy days will produce small waves that could compare to a calm surf. Works Cited Chiras, Daniel D. Environmental Science. Burlington, MA: Jones and Bartlett Learning, 2013. Print.
