- 2. Multiple Choice
the mechanism of evolution in which individuals that are better adapted are more likely to survive and reproduce to pass down their beneficial genes & traits
variation
overproduction

natural selection
- 3. Multiple Choice
random changes in DNA that leads to new traits that will be passed on IF beneficial to an organism's survival
mutations
variation
natural selection
overproduction
- 4. Multiple Choice
a scientific explanation that has been tested and supported by evidence
(hint: __________ of evolution)
theory
adaptation
evolution
idea
- 5. Multiple Choice
an inherited trait that increases an organism's change for survival
mutation
adaptation
evolution
overproduction
- 6. Multiple Choice
the adaptation that allows organisms to resemble (blend into) the surrounding environment, a defense mechanism used by many organisms
mimicry
camouflage
variation
evolution
- 7. Multiple Choice
the environment selects traits that help individuals survive and reproduce and the genes for those traits are passed on to the next generation
overproduction
natural selection
mutation
migration
- 8. Multiple Choice

Hawaiian Isalnds
Madagascar
Europe
Galapagos Islands
- 9. Multiple Choice

Charles Darwin
Jean Baptiste Lamarck
Aristotle
Chales Lyell

Charles Darwin
Aristotle
Jean Baptiste Lamarck
Thomas Malthus
- 11. Multiple Choice
the process of a population's genes changing over time as a result of natural selection and genetic variation
mutations
predation
mimicry
evolution
- 12. Multiple Choice
when a species produces more individuals than an environment can support leading to competition & the struggle to survive
evolution
natural selection
overproduction
mutations
- 13. Multiple Choice
differences among individuals of a species
clones
variation
adaptations
natural selection
- 14. Multiple Choice
an adaptation when an organism can resemble (copy) another
camouflage
mimicry
overproduction
predators
- 15. Multiple Choice
process by which inherited traits changed over time within a population
evolution
natural selection
overproduction
mutations
- 16. Multiple Choice
Suppose white rabbits and black rabbits live in the same environment where birds are predators. The environment is very snowy and there is plenty of food for both rabbits. One rabbit however is better adapted for this environment. According to the theory of natural selection what will most likely happen to the rabbits?
White rabbits will be favored to survive due to camouflage, so black rabbits will most to a place without white rabbits.
The white rabbit population will likely increase but the black rabbits will decrease in population until they possibly go extinct.
Both rabbit populations will increase because they will adapt by changing color.
The black rabbit population will likely increase but the white rabbits will decrease and possibly go extinct.
- 17. Multiple Choice
A female bird may lay more than 5 eggs at a time. There is not enough food to support all of the offspring. What is this an example of?
selection
variation
adaptation
overproduction
- 18. Multiple Choice
A rabbit's white fur allows it to camouflage with the snow. What is this an example of?
adaptation
selection
variation
species
- 19. Multiple Choice
Tiger tails can either be long or short. The length of their tails is determined by the genes they inherit for tail length. What term BEST describes these differences among the tiger tails?
traits
variations
predators
competition
- 20. Multiple Choice
How does natural selection lead to evolution?
Stronger offspring kill weaker members of the species.
Overpopulation provides food for stronger members of the species.
Environmental changes kill weaker members of the species.
Best adapted members of a species survive to pass on beneficial traits.
