Structural features with a common evolutionary origin

• Homologous structures

• Analogous Structures

• Vestigial strucutres

• Bitchigial Structures

A naturalist on the H.M.S. Beagle. Formed Theory of Evolution by Natural Selection.

• Thomas Malthus

• Alfred Russel Wallace

• Charles Darwin

• Jean Babtiste Lamarck

The change in populations over time.

• Evolution

• Genetic Drift

• Punctuated equilibrium

• Natural selection

A group of small islands near the equator, about 1000 km off the west coast of South America. Observations of the island fauna lead to the Theory of Evolution by Natural Selection.

• Fiji Islands

• Falkland Islands

• Galapagos Islands

• Aleutain Islands

A mechanism for change in populations where an organism with a favorable trait survives, reproduces, and pass the favorable phenotype to the next generation. Organisms without the favorable phenotype are less likely to survive and reproduce.

• Directional Selection

• Natural Selection

• Disruptive Selection

• Structural Selection

A British naturalist who proposed a similar theory of evolution but did not get much credit for his work.

• Thomas Malthus

• Alfred Russell Wallace

• Charlse Darwin

• Jean Baptiste Lamarck

Body parts that do not have a common evolutionary origin but are similar in function

• Analogous structures

• Homologous structures

• vestigial structures
