Fossilized remains of prehistoric mastodons show anatomical similarities to modern-day elephants. These similarities provided the first evidence that mastodons were related to modern-day elephants. Which of the following is the BEST additional evidence that mastodons were related to elephants?
A.
Mastodons walked on four legs like modern-day elephants.
B.
Mastodon tissues contained proteins with similar amino acid sequences compared to modern-day elephants.
C.
Mastodon fossils were found in the same area where modern-day elephants live.
D.
Mastodons ate a diet similar to that of modern-day elephants.
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?
A.Australia, the South Pacific, Indonesia, Malaysia
B.Europe
C.North America
D.Africa and the Middle East
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

- Denisovans are ancient humans. What would you least expect? A. They would have a larger brain than H. floresiensis. B. Fusion of chromosome 2a and 2b would not have occurred. C. Their mtDNA would show more similarity to Neanderthals than to H. sapiens. D. They probably did not have a spoken language. E. There would be evidence of them interbreeding with Homo sapiens and Neanderthals.arrow_forwardScientists conducted research to examine the evolutionary relationship between 10 bird species and an alligator species.
