Question
Chapter 13, Problem 4WIO
Summary Introduction
To determine:
Whether the bones found in the given case correspond to the plague victims of 1348.
Introduction:
Life began on earth about 3.6 billion years ago. Fossils help in determining the kind and age of an organism that existed during the early period of earth’s history. Dating helps in the evaluation of specific fossils for investigating evolutionary changes.

Students have asked these similar questions
Why are human and chimpanzee DNA 96 percent similar? Please choose the best option.a) Both groups show similarities in their fossil record.b) Humans and chimpanzees share several similar traits such as the use of tools.c) These two species descended from a recent common ancestor.d) Natural selection has favored those particular genes in both humans and chimpanzees.
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.
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
