Document Summary

Be able to categorize leading thinkers of the day on their view on evolution. The fossil record shows changes over time within particular locations- Boundaries between fossil strata caused by floods, earthquakes, etc. New species appeared in more recent layers by re-populating from elsewhere (species migrating) Evolution by natural selection- if you accept that natural traits are variable, And that there is a struggle for existence, evolution by natural. Wallace"s line, tectonics causing distribution of species and separately evolving. Know the distinction between geological theories of catastrophism and gradualism. Gradualism processes are the same as present day; geological change is very slow. : the earth is continuously modified by ^ these events. Descent with modification: explains the original of new species- evolve from ancestral species. Different resources favor different characteristics- change through time. Allows us to explain homology, species resemblances, and vestigial structures. Darwin"s 6 insights that led to his 3 inferences.
