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.
