Textbook Question
Chapter 25, Problem 7TYU
Fossilization continues even today. If you wanted to increase the probability that your deceased favorite pet would become fossilized, what actions would you take?
a. Place the corpse in an environment where decomposition is rapid (such as a forest).
b. Place the corpse in an environment where decomposition is slow (such as a swamp or bog).
c. Bury only the bones, since soft parts don’t fossilize well.
d. Place the corpse in an environment where plenty of oxygen is available.

This video refers to Denisovans as a “Ghost Lineage.” In fact, Denisovans don’t even have a formal scientific name. What is the physical evidence that anthropologists need to further define and understand the Denisovans?
A.
None of the above
B.
A Type Specimen (and more Denisovan fossils)
C.
Neanderthal DNA
D.
H. sapiens DNA
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 DNA of fossil hominins is too similar to modern humans, making it difficult to distinguish between them.
B.
The technology for extracting DNA from fossils hasn't been developed yet.
C.
The fossils would need to be in a -5 degree Celsius environment to prevent DNA from degrading
D.
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.

A.1.9 million years old in Kenya B.2 million years old in South Africa C.3 million years old in China D.5 million years old in Kenyaarrow_forwardUse the scenario to answer the question. A fossil indicates that whales might have started out as small land mammals. This animal was about the size of a wolf and had a diet of meat and fish. While the fossil has the body of a land animal, its head is shaped like a whale with an ear bone that is unique to whales. Which statement is likely true about the fossil? It is not a transitional fossil, but it shows correlation. It is not a transitional fossil, but it shows causation. It is a transitional fossil that shows causation. It is a transitional fossil that shows correlation.arrow_forwardFrom the early 1700s to the modern day, how did various lines of evidence clarify and improve scientists' understanding about the ancestry of cetaceans?

- The similarities between the bone structure of a human hand and a cats paw suggest what? a. a common evolutionary ancestor b. Humans are actually kitty cats c. nothing d. similar biological functionarrow_forwardAccording to "The Complex Evolution of Homo sapiens", all early Homo sapiens looked the same. They did not have any archaic traits. A. True B.Falsearrow_forwardUse the scenario to answer the question. Scientists have found one new fossil that is similar to Archaeopteryx. It is only the second fossil of its kind. It shows an animal that had a long-feathered tail and small teeth, like non-avian dinosaurs. But the animal also had flight feathers and wings, like modern birds. The fossil also shows a fused clavicle bone, which confirms the relationship between birds and dinosaurs because they are the only two groups with this characteristic, What is true about this scenario? It shows evidence of evolution. It shows evidence of causation. It shows evidence of climate change. It shows evidence of widespread expression.arrow_forward
