- 2what do we have that shows the world has change and living thingsantibiotic resistant bacteria/ volcanic islands
- 35 evidence of evolution in life on earth- fossil evidence
-structural comparison
-embryology comparison
-molecular comparison
-microevolution - 4-who came up with the scie. explan. for how evolution occurs? -when did he live? -Where did he travel? -What did he see? -What did he ask? -What was his book?-Charles Darwin
-!8 hundreds
-world and galapogos
-lot of living things/ diversity with similarities
-How could so much occurred?
-On The Origin Of Species - 5What is the theory calledNatural selection
- 6What were his three influences?-artificial selection
-great teachers-geologist& economist
-observation from voyage - 7Define Natural selectionsurvival and reproduction of the fittest/ pocket mice is an example
- 8$ 4requirements for natural selection- over production
-variation
-limit on population
-survival and reproduction - 9define adaptationfeature that enable survival
- 10Adaptions: 1. structural 2. behavioral 3. physiologicalDefine and Exam.
-body parts- wings, claws
-response to environment- hiding, dancing
-body function- venom, digestion - 11*Define variation/diversityslight differences in adaptations
- 12*what creates new combinations and possible onesmeiosis, sex. reproduction, mutations
- 13*How can diversity help with survivalthe more variation in a gene pool the less likely of extinction or better chance to survive/diversity increases survival
- 14what is a gene poolcollection of genes inn apopulation
- 15give and example of microevolutionlight + dark pocket mice
- 16difine speciesorganisms that can mate & reproduce viable offspring / healthy offspring
- 175 mechanisms that keep them from mixing- location
- time
-behavior
-anatomy(parts)
-genetics - 18what is speciationthe evolution of new species
- 19what is extintioncomplete loss of species
- 20are both still happeningyes
- 21how are humans classifiedhomo sapiens / primates
