Evolution Test Review ~ Mrs. Connor
Fossil the solidified remains or imprint of a previously existing organism
Adaptation The opposable thumb allows humans to grasp objects firmly Helped us survive over time
Natural Selection Individuals in a population that have traits or abilities that give them a competitive advantage over other population members and are more likely to survive.

Evolution by Natural Selection. Scientific Theory An explanation of natural phenomenon supported by a large body of scientific evidence obtained from.

Evolution Chapter 15. Evolution Evolution, or change over time, is the process by which modern organisms have descended from ancient organisms.
WHAT DOES THE WORD EVOLUTION MEAN?. The Theory of Natural Selection consists of the following four major points:
Why is life on Earth so diverse??? TEST: Friday 10/28.
LIFE OVER TIME What processes have created diverse species & adaptations throughout history? Theories of Evolution began when scientists began asking these.
How did life begin? Miller and Urey’s Experiment Passed sparks through a mixture of hydrogen methane ammonia and water This produced amino acids –
