- Lamarck
- Malthus
- Mendel
- Gould
- Leopold
A: Lamarck

Q: Adaptive radiation:
- is another term for natural background radiation that causes adaptive changes
- is the evolution of the biggest and fiercest animals
- is the formation of new adaptive structures or colors within a species
- is the evolution of many species that occupy many different niches, from a single ancestral form
- is the development of "radiant" fin structures on fishes, or development of fin like structures on dinosaurs
A: is the evolution of many species that occupy many different niches, from a single ancestral form

- biotic potential
- vestigial structures
A: natural selection

- natural selection
A: artificial selection

Q: Charles Darwin studied _____ while visiting the Galapagos Islands in 1835.
- frogs
- finches
- bison
- orchids
- whales
A: finches

Q: ___________ formulated a theory of evolution by natural selection.
- Charles Darwin
- Jean-Baptiste Lamarck
- Gregor Mendel
- Thomas Malthus
- Aristotle
A: Charles Darwin

Q: Evolution is a _____.
- theory
- hypothesis
- law
- belief
- invalidated idea
A: theory

Q: Identify the statement that is not a component of evolution by natural selection.
- overproduction of offspring
- differential survival and reproduction
- genetic variation
- limitless resources
A: limitless resources

Q: The primary evolutionary unit is the
- cell

A: population

Q: The fossilized remains of extinct organisms
- provides critical evidence that life has evolved over time.
- provide a complete record of evolutionary history.
- demonstrate that nature never "takes leaps" in evolution.
- is a frequent, common event.
- all of the above are true.
A: provides critical evidence that life has evolved over time.

Q: The fossil record is limited because:
- geologic processes may destroy fossils
- organisms tend to decay before they become a fossil
- only animals with hard parts are easily preserved
- very few organisms were preserved
- all of the above
A: all of the above

Q: Links between organisms that show branching pattern of evolutionary relationships are shown by_____.
- living fossils
- comparative embryology
- phylogenetic diagrams
- analogous structures
- disruptive selection
A: phylogenetic diagrams

Q: Which of the following is NOT in accord with the process of natural selection?
- The leaves of plants exposed to full sunlight are smaller than the leaves of plants growing in the shade, due to genetic differences between the plants.
- A mammal is born with the ability to produce a chemical that attracts members of the opposite sex, and subsequently has greater reproductive success than its siblings.
- In an insect that is the favorite prey of bats, a new mutation arises that gives it longer wings, allowing it to fly faster.
- In an island population, brown-colored individuals of a certain lizard species become more common than green individuals because a hurricane kills off all green individuals.
A: In an island population, brown-colored individuals of a certain lizard species become more common than green individuals because a hurricane kills off all green individuals.

Q: Remnants of organs or structures that were better developed and more functional in the ancestors of a species and now serve little or no purpose, such as the pelvis in some whales and snakes, are called
- remainder structures
- remnant structures
- vestigial structures
- venetian structures
- adaptative radiation
A: vestigial structures

- disruptive
- stabilizing
- directional
- divergent
- variable
A: stabilizing

Q: Compare and contrast sympatric and allopatric speciation and what is needed for each to occur.

Q: "Survival of the fittest" means the survival of those organisms
- with the largest teeth.
- with the largest teeth.
- that live the longest.
- that have the greatest number of matings.
- that can best cope with existing environmental conditions and live to reproduce.
A: that can best cope with existing environmental conditions and live to reproduce.
