B)a woolly mammoth preserved in thick ice
C)petrified wood
D)mold of a snail shell
8.
How do paleontologists determine relative ages of fossils in sedimentary rock? 4.e
A)Older fossils are found in the layers closest to the surface.
B)Younger fossils are found in deeper layers.
C)Older fossils are found in softer rock layers.
D)Older fossils are found in deeper layers.
9.
Which statement is supported by the fossil record? 3.c, 3.e, 4.e
A)The diversity of species on Earth has not changed since life first appeared.
B)Species do not change over time.
C)Which statement is supported by the fossil record?
D)Earth's climate has not changed over the past several million years.
10.
Which describes homologous structures? 3.c, 3.d
A)They can indicate how closely species share a common ancestor.
B)They appear similar, but have different ancestral origins.
C)They are the result of similar environmental conditions that produced similar natural selection outcomes.
D)They are identical structures in different species.
11.
Which best describes vestigial structures? 3.c, 3.d
A)They have an important function in the survival of the species.
B)Vestigial structures remain because they are genetically related to an advantageous trait of the species. Their loss would have harmful effects for the survival of the species.
C)They do not provide evidence of evolution.
D)They will develop into useful organs as the species evolves.
12.
What is embryology? 3.c, 3.d

C)the study of human embryos to cure diseases
D)the study of the development of embryos from fertilization to birth
13.
What is convergent evolution? 4.f
A)the process of evolution that takes place as plate tectonics bring continents closer together
B)the creation of new species by breeding members of different species
C)the process by which species evolve independently in similar environmental conditions
D)the adaptations of one species to mimic another species in its environment
14.
Which is the second largest group in the classification hierarchy? 3.d
A)Phylum
B)Class
C)Kingdom
D)Order
15.
Who developed the classification system that grouped organisms based on similar physical structures? 3.d
A)Aristotle
B)Linnaeus
C)Darwin
D)Mendel
