What are the key evelutionary trends and other developments in early Homo?

Working as an Anthropologist in South Africa, you’ve been given four hominin craniums and are asked to develop a new classification system. Using cranium size, the robustness of the cheek bones and brow ridges, and the prognathism of the face, how would you categorize these four skulls into species? Would you categorize all four of them as belonging to the same genus? Two geneses? Three geneses? Four geneses? Do you believe any of them are the same species? Explain how you would categorize these four specimens. Explain what features you used to categorize these specimens. This is the image of the 4 different hominin individuals

In your Introduction to Biological Anthropology class, your instructor asks you to examine a fossil skull and determine which species it is. You note there is a sagittal keel at the top of the skull. Based on this information alone, to which species does the skull belong? A. Australopithecus boisei B. Homo habilis C. Australopithecus garhi D. Homo erectus

According to "Our Earliest Ancestors", why can’t scientists just do DNA analysis on these fossil hominins to determine if they are a separate species and possibly what species they belong to?    A.The technology for extracting DNA from fossils hasn't been developed yet. B.Scientists can't perform DNA analysis on fossil hominins because the fossils have been contaminated with modern human DNA over the years, making it impossible to isolate the ancient genetic material. C.The fossils would need to be in a -5 degree Celsius environment to prevent DNA from degrading D.The DNA of fossil hominins is too similar to modern humans, making it difficult to distinguish between them.

Primitive men evolved in _________.a) Africab) Americac) Australiad) India

According to "The Complex Evolution of Homo sapiens", what is the significance of the L3 gene and who was the L3 woman?    A.Only individuals within North and South America descended from the L3 woman. B.All individuals within Africa are descended from the L3 woman. C.All individuals outside of Africa and who live in the Old World are descended from the L3 woman. D.All individuals outside of Africa are descended from the L3 woman

It is thought that jaws, which are found in the higher vertebrates, evolved from: a. progressive hardening of the cyclostome mouth. b. cartilaginous arches used to support gills. c. small bones associated with the brain capsule. d. the bony teeth found on lamprey tongues.

Along comes Dr Phil Bell and deep in the mines of Lightning Ridge, finds an amazingly preserved pterosaur that preserves feathers. He hypothesises that this means that feathers must have evolved before the origin of dinosaurs and therefore must have been primitive. How would you go about testing this hypothesis of feather origins?
