Q

Carolus Linnaeus

A
  • classification system (still used)
  • binomial naming system (a nested sytem grouping similar species into increasingly general categories)
  • grouping based on the “pattern of their creation”, not evolutionary relationships

Paleontology

A

study of fossils

developed by Cuvier who did not believe in evolution

he believed in catastrophism

Q

Jean Baptiste Lamark (1744-1829)

A

Before Darwin

Wrong mostly, but got people thinking

first comprehensive theory of evolutionary change

Use and disuse, inherited acquired characterisitcs, species change over time (right), organisms strive for improvement, lineages did not branch or go extinct.

Q

biogeographical problems for Darwin

A

Noticed island speices were similar to mainland ones, but were still different. Some were unique to islands.

Q

Artificial Selection

A

Humans modify species over generations by breeding for specific traits. Darwin was able to argue that this could happen in nature.

Q

Theory of Natural Selection

A

A. more individuals are produced than can survive “struggle for existance”

B. Heritable variation within populations. Non-random survival and reproduction. Successful traits become more common.
