The process in which inherited characteristics within a population change over generations such that new species sometimes arise
What is Evolution?

What is the Fossil Record?
200
A theory (explanation) supported by evidence for how populations change over time
What is evolution?
200
Overproduction, genetic variation, selection, and adaptation.
What are the four parts of natural selection?

500
The human practice of breeding animals or plants that have certain desired traits`
What is artificial selection?
500
Over generations, adaptations become more common and genetic differences add up
How do species change over time?
500
Common structures, similar DNA, and developmental similarities
What other evidence supports evolution?
500
Fossil evidence shows that organisms have changed over time
How do fossils provide evidence that evolution has taken place?
