Biology Ch.10 Flashcards
Which scientist proposed that is an organism used a structure so much that it grew the trait of that larger structure could be passed to its offspring. A. Darwin B. Lamarck C. Buffon D. Lyell
B. Lamarck
Which of the following is a for a group of similar organisms that can reproduce and produce fertile offspring? A.individual B.population C.species D.fossil
C.species
The “present is the key to the past” describes the theory of
Uniformitarianism
Which of the following is a fossil?
A. A plant that has recently died
B. A group of similar organisms that can reproduce
C. A structure or organ that no longer functions
D. A trace of an organism that existed in the past
D. A trace of an organism that existed in the past
The theory that landforms on earth surface such as mountains waterfalls and canyons were created as the result of sudden spectacular events is Cold the theory of
Catastrophism
The difference in the physical traits of an individual for those of other individuals in the group is called a
Variation
Overtime adaptions can lead populations to experience
Genetic changes
What did Charles Darwin observed in Finch populations on the Galapagos islands off the coast of South America?
Different species on different islands
What did Charles Darwin learn from the fossils of a giant armadillo that he had found in Argentina?
Modern animals may be related to fossilized organisms
Fossils of marine organisms high in the Andes Mountains led Darwin to conclude that
Great change can happen over time
The development by scientist of a new color in a Rose is the result of
Artificial selection
In natural selection the selective agent is the
Environment
All the rabbits living in a particular area would be an example of
Population
A bird that can easily outcompete other birds for food and that can produce many eggs has a high
Fitness
Which of the following describes natural selection? A. It acts on genetic material directly B. It acts on existing physical traits C. It forms new traits D. It forms new genetic material
B. It acts on existing physical traits
Which of the following is an example of a vestigial structure? A. The wings of Redtailed Hawk's B. The hindlimbs of a house cat C. The fins of a shark D. The wings of an ostrich
D. The wings of an ostrich
Distributions of organisms around the world
Biogeography
What is suggested by the similarity of early embryos of different species of vertebraes?
Recent common ancestry
Some organisms that share a common ancestor have features that different functions but similar structures. These are known as
Homologous structures
If an organism has a vestigial structure that structure likely once had a function in a
Early ancestor
Paleontology is the study of
Fossils
Two organisms that are closely related would have
Very similar DNA sequences
Gene sequences that no longer function
Pseudogenes
Evolution is considered to be one of the most important theories in science because it
Unites the field of biology geology chemistry and ecology
Protein sequences in one organism that resemble those of another suggest a
Shared ancestry
