Natural Selection

Evolution

• the gradual change in species over time

• a process by which individuals that are better adapted to their environment are more likely to survive and reproduce than others that are not

• any change in the DNA of an organism.

• behavior or physical characteristic that allows an organism to survive and reproduce in its environment

  behavior or physical characteristic that allows an organism to survive and reproduce in its environment

Charles Darwin

• British naturalist who formulated the theory of Evolution by natural selection

• any difference between organisms of the same species

• the variety of organisms that inhabit the Earth

• the preserved remains or traces of an organism that lived in the past

Missing Link

• gaps in the fossil record that provide proof of Evolution

• similar structures that related species have inherited from a common ancestor (example – bones in bird’s wing, dolphin fin, and dog leg are very similar)

• process where scientists look at the half-life of chemicals contained in rocks around a fossil to determine the age of that fossil.

• the disappearance of all members of a species from Earth
