Evolution and Natural Selection Tutorial (PowerPoint)
Defined natural selection
Defined evolution
Disproved Lamarck’s theory of “inheritance of acquired characteristics”
Introduced Darwin’s points for natural selection
organisms have high reproduction but populations remain constant
resources are limited – leading to competition
populations have variation
variation is heritable
some traits enhance fitness
Defines adaptations
Explains that populations evolve, not individuals
Gave examples of natural selection
Showed evidence of natural selection
artificial selection
fossil record
homologous structures
adaptive radiation
coevolution
Darwin’s Finches and natural selection (PowerPoint)
Gave actual data from the Galapagos islands showing natural selection
Guppy Evolution Worksheet (with website)
Let you manipulate environmental factors to show variation in a trait
Student Handout “natural selection in action”
let you choose which trait would be more fit and justify why the environment would
select for it
Bellringer writing
What is the difference between evolution and natural selection? Give an example of
each.
Vestigial Organ Discussion notes
Showed human and animal organs which are no longer used but still exist
Discussed why they might still exist
Related these to natural selection
