Question 10 Which data most strongly supports the "Out-of-Africa" hypothesis? A Fossils found in Africa are generally smaller than those found on other continents. DNA sequences from extant African hominins are more diverse than extant hominins from other continents. The synapomorphy of hominins (bipedalism) indicates that ancient humans walked out of Africa. DNA sequences from extinct hominins are more diverse than extant hominins.

A paleontologist finds a hominid fossil skull in a stratum dated at 4.4 MYA in eastern Africa. The skull has a relatively small braincasea and similarly-shaped teeth. Which of the following hominid species would the skull most likely be a fossil of? Homo erectus Ardipithecus ramidus Australopithecus africanus Homo neanderthalensis

Put the following hominins in order from the oldest to youngest in terms of when they first appear in the fossil record. The Denisovans Ardipithecus kadabbe Paranthropus Australopithecus aforensis Homo erectus

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 False

What do you think about the hypothesis that language evolved as a way for early hominins to communicate about stone-tool manufacturing? What other hypothesis could you come up with as to why language evolved in our Hominini tribe?

Homo erectus was most likely the first hominid to successfully migrate to regions beyond Africa. Discuss how the biology and culture of Homo erectus led to its success on three major continents with varying environments

Radiometric dating and the cranial capacity measurements are back from the paleolab for the specimen your friend at the museum called you about.  She calls again to tell you the results.  The cranial capacity is 442 cubic centimeters and it dates to 3 million years ago.  After having identified the cranial traits present, you can now take this new information and provide, at least, the genus you think it could belong to in order to help your friend. Based on this information, choose from the options below, the category to which you think it most likely belongs. Group of answer choices Robust Australopithecine early Genus Homo Pre-Australopith Late Genus Homo Gracile Australopithecine Premodern

QUESTION 3 Which of the following are ways in which early hominins differed from apes? (select all correct answers) Increased bipedalism Decreased sexual dimorphism Lack of a tail Larger body size

list TWO similarities between early members of the genus Homo (e.g. H. habilis) and Homo erectus/ergaster that earlier hominins (e.g. gracile Australopithecines) do not have?
