- Because the Laetoli footprints date to 3.6 mya and they are clearly made by a bipedal hominin, it is likely that they were made by Australopithecus afarensis, who appears to have been the only hominin around at that time. True O FalseWhich statement is a tenet of the out of Africa hypothesis for the origin of modern humans? O O O O Modern humans evolved in Africa and then migrated throughout the world, replacing earlier human populations. O 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. O Numerous Homo erectus populations that scattered throughout the world evolved simultaneously to give rise to modern humans.43. Which of the following recent fossil discoveries dating between 4.4 – 5.8 mya was clearly bipedal as reflected by features of the hip and thigh bone, but still had long, curved toes and an opposable big toe set off to the side (i.e., with a saddle joint like a thumb), leading human paleontologists to suggest that the fossil species is relatively close to our last common ancestor with other African apes? Orrorin tugenensis Archaic Homo sapiens Homo sapiens neanderthalensis Homo habilis Homo erectus
- This West Indian manatee (Trichechus manatus) is an aquaticmammal. Like amphibians and reptiles, mammals are tetrapods (vertebrates with four limbs). Explain why manatees areconsidered tetrapods even though they lack hind limbs, andsuggest traits that manatees likely share with leopards andother mammals (see Figure 26.12b). Discuss how early members of the manatee lineage might have differed from today’smanatees.Brown et al. and Morwood et al. reported in 2004 that they had found skeletal remains of a previously unknown type of hominin, now dubbed Homo floresiensis, on the Indonesian island of Flores. These hominins were small (approximately 1 m tall) with small braincases (approximately 380 cm3) as compared with other hominins. The remains of H. floresiensis were found alongside handmade stone tools and the remains of dwarf elephants that also inhabited the island, suggesting that H. floresiensis was able both to make tools and to coordinate the hunting of animals much larger than itself. H. floresiensis is estimated to have lived at the site where the remains were found from 700,000 years ago to 60,000 years ago. Which would be the most feasible method of figuring out to which other hominin species H. floresiensis was most closely related? Compare the average body size of H. floresiensis to that of each of the other hominin species. Compare the type of prey hunted by H. floresiensis to that…Australopithecus afarensis (Select] [ Select] is the oldest definite bipedal hominid discovered to date is the largest collection, and the most well-studied species of Australopithecus Question 28 is only found in South Africa had a fully modern postcranial skeleton all of these I en+ svidence indicates
- Two individuals from the San tribe in Africa are more diverse from one another than two individuals from Europe and Asia. This is possibly because hunter-gatherers in Africa share DNA with a variety of other hominin species while only one Homo species populated other regions of the planet. is this statemnet true or false52. Which of the following represents the earliest Anatomically Modern Homo sapiens (AMHS) skeleton dated to approximately 190,000 YBP Omo I, Kenya Skuhl V, Israel Shanidar, Iran Mungo 3, Australia Homo floresiensis, IndonesiaAmong a population of tadpoles, the correlation coefficient for size atmetamorphosis and time required for metamorphosis is −0.74. On thebasis of this correlation, what conclusions can you draw about therelative sizes of tadpoles that metamorphose quickly and those thatmetamorphose more slowly?
- the evolutionary relationship between mode O Humans are descended from chimpanzees O Humans and chimpanzees had a common ancestor several millior ears ago Humans and chimpanzees had a common ancestor several million years ago; sinc Chimpanzees are more closely related to gorillas than they are to humans QUESTION 2 Which of the following statements about hominins is FALSE? ALS Each hominin species on Earth was directly descended from the species that preced 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 e QUESTION 3 Which of the following are ways in which early hominins differed from apes? (select alOutline the specific differences in the pelvis and the femur, and associated muscles, that are associated with the shift from quadrupedal locomotion in chimps to bipedalism in hominids and modern humans.A number of comparisons of nucleotide sequences among hominidsand rodents indicate that inbreeding may have occurredmore often in hominid than in rodent ancestry. Bakewell et al.(2007. Proc. Nat. Acad. Sci. [USA] 104: 7489-7494) suggest thatan ancient population bottleneck that left approximately 10,000 humans might have caused early humans to have a greaterchance of genetic disease. Why would a population bottleneckinfluence the frequency of genetic disease?
