Biología Evolucionaria El Futuro de la Evolución Humana: Selección artificial y transhumanismo por David Warmflash, MD, Nathan H Lents, Ph.D. Lectura Prueba Teach with this Evolution and natural selection are the same thing. false true Why do some researchers doubt that humans will continue to evolve through natural selection? The human population has started leveling off and will be stable at 9 billion by mid century. Modern healthcare enables the weakest to survive to reproductive age. Genetic engineering has made natural selection obsolete in many species on Earth. Humans have not evolved since the Stone Age. Natural selection will provide humans with: larger brains webbed hands or feet improved vision or hearing none of the above The phrase "survival of the fittest" says that individuals born with traits that _____ survival to maturity are more likely to grow up and reproduce compared with individuals lacking such traits. impede bottleneck enhance reduce Natural selection is occurring among humans in response to the HIV virus. true false The process that affects evolution due to human activity is known as _____. artificial selection founder effect genetic drift natural selection An example of artificial selection is: After a large population is destroyed, a smaller population repopulates the species. A small group if individuals breaks off from a larger population to relocate. Women with wider hips due to caesarian section births. Women with more narrow hips due to caesarian section births. Which of the following factors is plausible as an evolutionary force for human colonists of other planets to become a new species: Isolation from the rest of humanity for a very long time. Living in a complete lack of air. Constant influx of immigrants from Earth. Invention of very rapid propulsion to allow travel to new colonies. Resultados de Prueba
