Adaptations and Change Over Time Flashcards
Sexual reproduction
A reproductive process that involves two parents
Asexual reproduction
A reproductive process that involves only one parent
Species
A group of similar organisms that can mate with each other
Adaptation
An inherited behavior or physical characteristic that helps an organism survive and reproduce in its environment
Evolution
Change over time
Scientific Theory
A well-tested explanation for a wide range of observations or experimental results
Natural Selection
The process by which organisms that are best adapted to their environment are most likely to survive and reproduce.
Variation
Any difference between individuals of the same species
Behavioral Adaptation
A behavior that helps an organism survive and reproduce in its environment
Structural Adaptation
A physical characteristic that allows an organism to survive and reproduce in its environment
Physiological Adaptation
A biochemical function that makes an organism better suited to its environment
Hibernation
An animal’s state of greatly reduced activity that occurs during the winter
Migration
The regular, seasonal journey of an animal from one place to another and back again
Selective breeding
A process in which only organisms with a desired characteristic are bred
Environmental pressures
Indicators of environmental pressure reflect the impact of human activities on the environment
