The synthesis of DNA and RNA from the organic soup would have been guided by the actions of enzymes in the
A. clay-catalyst hypothesis
Fossils used to identify geological periods are _________ fossils.
Some viruses never use DNA to carry out protein synthesis and have only RNA as their genetic material. This would lend evidence to which theory?
A. endosymbiotic theory of eukaryote evolution
Birds and insects both have wings, but we do not consider this similarity as evidence of relatedness because
A. bird wings function on different physics principles of
Marsupials are more numerous in Australia than South America because of less competition with placental mammals.
A line of evidence NOT considered by Darwin in his development of the theory of natural selection is
A. comparative biochemistry
Analogous structures serve the same function, are similarly constructed and are inherited from a common ancestor.
The first cell gave rise to
A. bacteria and archaea
Africa, Asia, South America, and Antarctica share some patterns of primitive (fossil) plants and early reptiles, but do not have similar mammal populations. These findings
A. suggests that the mammals evolved earlier while continents were
joined, but plants & reptiles radiated into diverse groups after
Which of the following is NOT involved in natural selection?
A. organisms differ in reproductive success
Darwin observed that
A. members of a population vary in their functional, physical and
A. have occurred at least 5 times in the Earth's history.
It is likely that the protocell was
Which piece of evidence would be best support the theory of continental drift?
A. the east coast of Africa matches up with the western coast of
Which statement is NOT true about a protocell?
A. it would have been present before the development of a true
All of the following statements concerning the theory of continental drift are true EXCEPT
A. the unique distribution patterns of several fossils is explained
by continental drift.
When we compare amino acid differences to estimate the evolutionary "distance" between organisms, what assumptions are being made about the rate at which mutations occur over time?
It is constant, linearly, and at the same pace. It also assumes that the following changes are not undoing the previous ones, that's because mutations occur randomly and not at a constant rate.
The organisms on the Galápagos Islands that were most important to the development of Darwin's theory of natural selection were
A. rabbits and hares.
________ discovered that a variety of amino acids and organic acids could be produced in the laboratory in a reducing atmosphere with electrical sparks.
A. Sidney Fox
The first person who proposed that small organic molecules could have arisen by chemical evolution was
A. Sidney Fox.
