Which statement is a tenet of the out of Africa hypothesis for the origin of modern humans? O O O O O Modern humans evolved in Africa and then migrated throughout the world, replacing earlier human populations. Modern humans evolved in Eurasia and migrated to Africa, driving resident populations of early humans out of Africa and resulting in their extinction. Homo erectus populations migrated out of Africa and interbred with Homo neanderthalensis populations in Eurasia to give rise to modern humans. Numerous Homo erectus populations that scattered throughout the world evolved simultaneously to give rise to modern humans.

Starting with the work of Thomas Huxley, Charles Darwin based his theory of human origins on which set of observations? Since the fossil record known at the time linked humans and orangs, both Huxley and Darwin assumed humans evolved in Asia. O There was an excellent fossil record of human evolution from which Huxley and Darwin concluded that humans had a close evolutionary relationship with the African apes. O Humans are bipedal while other apes are not, humans have larger canines than other apes, humans are tool users, and humans have larger brains. Humans are bipedal while other apes are not; humans have smaller canines than chimps, gorillas, or orangs; humans are tool users; and humans have larger brains.
In studying recent fossils of the genus Homo, such as Cro-Magnon,biologists have determined that modern humans have not undergonemuch biological evolution in the past 50,000 years. Rather, culturalanthropologists argue that cultural evolution has been far moreimportant than biological evolution in the recent history of modernhumans. What do they mean by this? Support your argument withsome examples.
Which statement is true about the Neanderthals? O A. They originated around the same time period as homo sapiens and coexisted O B. Homo sapiens rapidly killed off all the Neanderthals as they had superior fighting technology like the bow and arrow and spears O C. Neanderthals interbred with Homo sapiens and as a result assimilated with Homo sapiens O D. They were only living in Europe where they had genes allowing them to acclimate to that particular environment. OE. Neaderthals were the likely direct ancestors of the newly discovered pigmy island species of humans, H. floresiensis and H. luzonensis

What can we say about Homo sapiens? Select one: O a. Originated in Africa, shared a common ancestor with Neanderthals, Denisovans, and most likely descendants from a group related to Homo heildenbergensis O b. Migrated out of Africa, most likely 2 million years ago, hybridized with Homo floresiensis and differentiated from other Homo as the sole species to evolved language. O c. Migrated from Ethiopia 200,000 years ago, hybridized with Denisovans and Neanderthals to later replace them O d. Is the result of hybridization between Neanderthals and Denisovans, only lineage to show bipedalism and posses the largest brain capacity of all Homo O e. A and C are correct
You have discovered a 2.1 million year old fossil with a parabola-shaped tooth row and a brain size of 600ec. Nearby were some Oldowan tools. What species of hominin should it be placed in? O Paranthropus boisei O Homo habilis O Andipithecus ramidus O Australopithecus afarensis
Which of the following statements about hominins is FALSE? Each hominin species on Earth was directly descended from the species that preceded it Multiple hominin species lived at the same time The genus homo arose about 2.5 million years ago We have now discovered a vast number of hominin fossils, allowing us to trace the evolution of humans fairly well
Neanderthals are recognizably human but have distinctive facial features and a stocky build that were evolutionary adaptations to cold, dry environments. They shared Europe for 10,000 years with Homo sapiens. Today they no longer exist. Beyond these facts the fate of Neanderthals has generated much debate. Why did Neanderthalsbecome extinct? State at least two major factors toexplain their fate.
Scientists know that the last common ancestor between chimpanzees and humans lived 5-7 million years ago because: O It lived shortly after the disappearance of the dinosaurs at 10 million years ago. O The carliest hominins were found in woodlands The time the last common ancestor existed can be calculated by comparing chimpanzee and human DNA and using a "molecular clock" O Chimpanze fossils first appear in the fossil record 10 million years ago
It is generally accepted by anthropologists and biologists that modern humans arose: 500,000-1,000,000 years ago 350,000-450,000 years ago O 200,000-350,000 years ago 30,000-50,000 years ago O 5,000-7,000 years ago
