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
In the book, Jurassic Park, by Michael Crichton, scientists are able to reconstruct dinosaurs by getting dinosaur DNA from a mosquito that had been well-preserved in amber since the era of dinosaurs. Do you believe this can actually happen in real life? Why?
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
(1) What is the most common way for a dead organism to avoid decomposition?
(2) Why do researchers look for fossils in places that are now dry and barren instead of
other places like forests or grasslands?
(3) What kind of dating from the lecture or textbook would be the best method for finding
the number of years ago when a volcanic rock was formed?
(4) Why is the pelvis of a biped shorter and wider than the pelvis of a quadruped?
(5) Does the overall shape of Lucy’s pelvis resemble the human pelvis or the chimpanzee pelvis more? Do not think of the size, but compare the outlines of each
bone.
This is Lucy's skelton below.
