Students have asked these similar questions
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 fossils would need to be in a -5 degree Celsius environment to prevent DNA from degrading
B.The DNA of fossil hominins is too similar to modern humans, making it difficult to distinguish between them.
C.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.
D.The technology for extracting DNA from fossils hasn't been developed yet
According to " Denisovans: Decoding the Secrets of Our Mysterious Ancient Cousins”, where in the world are the highest concentrations of Denisovan DNA in modern, living humans?

B.Europe
C.North America
D.Africa and the Middle East
You are reading a scientific paper regarding the relationships of the anatomical and behavioral characteristics of chimpanzees and their implications for early hominid evolution. With the emphasis on anatomical and behavioral characteristics, this implies that the researchers are relying on

B. Nonevolutionary classifications of chimpanzees and humans
C. An incorrect classification of human ancestors
D. Cladistic classifications of chimpanzees and humans
