Question
For our last class, we read and discussed several papers focused on understanding the timing of evolution of humans and whether they emerged from Africa as Homo sapiens or evolved from an ancestor following their migration out of Africa. Is the modern consensus that Homo sapiens emerged from Africa or evolved elsewhere? Support your answer with one or two concise sentence(s) explaining why. This sentence should include two types of evidence. Match the authors with the molecules used in their study: Vigilant et al. Ingman et al Li et al. Ful -genome SNPs mtDNA control region sequence Complete mtDNA sequence (excluding control region) The following people (or pairs of people) made important contributions to our current understanding of evolutionary mechanisms. Summarize (one or two complete sentences) the major contribution of 8 of the following 10. Sewall Wright: Charles Lyell: Thomas Malthus: Georges Cuvier: James Hutton: Hardy and Weinberg: Woese, et al. Amotz Zahavi: Buffon: Eldredge & Gould:Explanation / Answer
African origin of modern humans is a based on number of therory put forward like out of Africa therory and recent African origin model according to which modern humnas That is Homo Sapiens evolved and Africa and migrated recently 50,000 to 1,00,000 years ago.
Another evidence is the fossil found in Ethiopia Africa shows beginning of skull changes that we see in modern humans. And also projecting chin.

5)Sewell Wright-He was the founder of population genetics.Modern elolutinary synthesis combining Genetics with evolution.
Charles Lyell-Lyell's version of geology came to be known as uniformitarianism, because of his fierce insistence that the processes that alter the Earth are uniform through time. Evolution took place from one generation to the next before our very eyes, he argued.
Thomas Malthus-He wrote the principles of population where is said human race would overproduce if not kept under control.
Georges cuvier-contributed to Darwin therory of evolution particularly natural selection in proving some species have gon extinct over time.
Jmaes Hutton-He originated the theory of uniformitarianism which inspired Lyell.
Hardy weinberg-Hardy-Weinberg equilibrium principle describes the unchanging frequency of alleles and genotypes in a stable, idealized population. In this population we assume there is random mating and sexual reproduction without normal evolutionary forces such as mutation, natural selection, or genetic drift.
Buffon-was an early advocate of the Linnaean classification system.
Amotz Zahavi-handicap principle explain how evolutionmay lead to "honest" or reliable signaling between animals which have an obvious motivation to bluff or deceive each other.
