Final Jeopardy

Final Jeopardy. They must compete for food and shelter with other living things. This competition causes species to either die out or evolve. *This seems like Natural Selection to me!. How does the movement of new individuals into a population help bring about rapid evolution?. $200.

Darwin and Science

Darwin and Science. No evolution at present No new species No known mechanism for evolution No fossil evidence No order in the fossils No evidence from similarities No evidence that evolution is even possible No evidence from molecular biology. No evolution at present.

Evolution Review 7A

Evolution Review 7A. Describe the conclusion that can be made about the fossils in layer A and layer B. Layer B contains younger fossils. Layer A contain older fossils. Layer B contains fossils from more complex organisms. Layer A contain fossils from less complex organisms.

Macroevolution: Part III Sympatric Speciation

Macroevolution: Part III Sympatric Speciation. Types of Speciation: A Review. Allopatric speciation is the evolution of geographically isolated populations into distinct species. There is no gene flow, which tends to keep populations genetically similar.
