QuestionAnswer
A trait that helps an oranism survive and reproduce Adaptation
A gradual change in a species over time. Evolution
The process by which individuals that are better adapted to their environment are more likely to survive and reproduce than other members of the same species Natural Selection
A well-tested concept that explains a wide range of observations Scientific Theory
A group of similar organisms that can mate with each other and produce fertile offsrping Species

Any difference between individuals of the same species Variations
What did Darwin observe on the Galapagos Islands that he thought was the result of evolution? Different adaptations among organisms
Why are variations needed for natural selection to occur? If not for variations all organisms would be equally adapted to their environment and equally likely to survive and reporduce
What is geographic isolation? organisms become isolated from the reswt of the species and remains separated long enough to evolve different trait
