Textbook Question
Chapter 13, Problem 4WIO
The bubonic plague swept through western Europe in 1348. Suppose researchers use 14C dating on the skeletons of suspected plague victims, and they discover that about 50% of the original amount of 14C remains in the bones. Are the bones the remains of plague victims?

Astronomers have made great strides in sending probes out to other planets and moons in our solar system. If they were to find a living creature some place other than Earth, how could DNA analysis help them better understand the organism? Explain in 1–2 sentences
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.
