Natural Selection by Charles Darwin
Understanding Natural Selection stresses the theory that a genus’s environment determines the likelihood of survival. Charles Darwin explains the importance of natural selection and sexual selection. Natural selection affects a given organism in its specific environment and how they adapt. Sexual selection focuses on a male and female relationship. Throughout the passage, Darwin gives various examples that define the meaning of each topic.
Natural selection is studied across the world. All that is good is accepted, and in contrast, all that is bad is rejected (Darwin 926). Every organism is examined for its natural and unnatural conditions of life (926). While the hands of time continue to turn, we do not realize these changes in nature until they are assessed through ancestry (926). When the …show more content…
transformation of different organisms is observed, we see only the attributes of each species and not the geographical variations (926). Darwin provides the concept that the color of an organism relates to where they reside in an environment (Darwin 927).
These characteristics of color provide protection and attraction of predators. The hue of an organism is in relation to their environment; if that were to change the species could potentially become endangered (927). In some cases the pigmentation of an animal or insect keeps an environment at ease. The color and/or smell of a creature can attract a predator. If the color of that being were subject to change, that organism could potentially over populate a given area (927). Sexual selection does not relate to the death or well-being of an organism, but the potential to conceive offspring (Darwin 929). It relies on the ability of an organism to obtain a mate in its natural environment (929). Males impress the opposite sex with beauty and physical advantages. With few males not having the capability to compare to a superior male, those individuals will not be able to reproduce (929). With this detriment, you begin to see changes in a
species.
Understanding Natural Selection examines life and the way an environment stays constant. Natural selection goes in depth on how different creatures seem to survive through time. In relation to the natural selection, sexual selection examines how different organisms reproduce and the struggle that can transpire. In this text, Darwin models his theory through thorough examination of nature.
