evolution

What is evoulution

• species adapt over time in response to their changing environment

• Changing over time

• genectic change

• Vestigal strucuturs

Know the early scientists and their contributions to the idea of evoultion

• Linnaeus: classification system from kingdom to species

• Buffon: species shared ancestors rather than sepreate.

  Darwin: Morecomplex forms of developed from less complex forms

• Lamarck: enviroment changes leads to disguise of strucutre

• All answers

Fossil aging /law of superposition

• Rock layer

• Natural selection

• he oldest rock layers will be on the bottom, with successively younger rocks on top of these,

• Artificial selection

Define species

• Animals living in the same environment

• a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding.

• Vestigal structures

• Homologous structures

know the various theories of geologic change

• Catastrophic: observe fossils in that were in earth quakes that were responsible for extinction

• Gradualism: Slow changes over time

• Uniformitarianism: Geologic processes that shape Earth are uniform through time

Darwin's theory of evolution by natural selection

• Natural selection

• Inherited beneficial adaptions produce more offspring on average than do other individuals

• Genes that are together

• Gene varaition

what is the variation? how can variation benefit a population

• a different or distinct form or version of something. It can make a population have different functions

• different things

• A group of people with the same traits

• Natural selection
