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

Is this bone and skeletal morphology a homology?   a. Yes, it is a homology   b. No, it is not a homology   c. Not enough information to tell   d. The answer depends on the specific diet of each species

The nuclear DNA of the Denisovans tells us that they: A. Are more closely related to Neandertals than Homo sapiens. B. Interbred with modern humans expanding out of Africa after 50,000. C. Evolved from Southeast Asian Homo erectus. D. Both A and B. E. None of the above.

The size of the head of the femur reflects the magnitude of force normally applied across the joint during locomotion as well as the contribution of body mass.

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?
