Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

As cells develop, signaling pathways can cause some genes to be turned off during development. b. Adult cells have different DNA content than do embryonic stem cells. c. Emybronic stem cells pose less of a threat for organ rejection as do an individual s own adult cells. d.

Which statement/s can best explain how evolutionary perspective help us understand senescence? (a) Evolutionary theory allows scientists to compare closely related species that differ inhow they invest in reproduction and in body maintenance, to test for effects on the agingprocess. (b) Understanding evolution can generate predictions about how individuals with certain suites of life-history characteristics might fare in the aging process when compared to other individuals without those characteristics. (c) Because aging is a natural process for all species, explaining its evolution through natural selection is insufficient. (d) Evolutionary studies provides insight into the historical development of adaptations, such as the number of offspring an individual has, that may contribute to life-history trade-offs, such as aging.
