Science Quiz 18 Flashcards
is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
Natural Selection
the action of using someone or something as a model.
Imitation
the act or art of copying or imitating closely.
Mimicry
a defense or tactic that organisms use to disguise their appearance, usually to blend in with their surroundings.
Camouflage
choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics.
Selective Breeding
something an animal does usually in response to some type of external stimulus in order to survive.
Behavior Adaptation
a physical or behavioral feature of an animal that helps them better survive in their environment.
Physical Adaptation
refers to the internal organs, tissues and cells.
Physiological Adaptation
Interbreeding populations of organisms that can produce healthy, fertile offspring
Species
Differences between individual members of a population
Variation
Trait that increases a population’s chances of survival
Adaptation
Habitat and the role a population plays in that habitat
Niche
Ability of an organism to survive and reproduce in its environment
Fitness
What are Darwin’s five main points on natural selection?
- Population has variations
- Some variations are favorable
- More offspring are produced than survive
- Those that survive have favorable traits
- Populations change over time
