Werth An Evolutionary Focus Improves Students’ Understanding of All Biology
If Darwin hadn’t developed idea, someone else would have
AR Wallace developed the same idea independently!
Difference between scientific explanation and pejorative “Darwinism”
o A theory in scientific sense, but not in vernacular sense
o Darwin spoke of descent with modification, not evolution
o Not a single theory but a suite of interconnected ideas, including
Natural selection
Artificial selection
Sexual selection
Common ancestry
Gradual, steady, incremental change
Importance of extinction
Intelligent design
o Evolution in action: can we see evolution occurring in the world today?
o What about evolution of eyes and “irreducible complexity”?
o “Transitional forms” and whales with legs
o Gene families (for example, globins) and evolution
o Chromosomal changes in humans and apes
Frequent criticisms of evolution
o Can we see evolution in action (occurring in the world today)?
o What about evolution of eyes and “irreducible complexity”?
o Intermediates: no “transitional forms” vs whales with legs
o Does evolution violate laws of thermodynamics?
o Adaptation within species doesn’t lead to appearance of new species
o If we evolved from monkeys, why are there still monkeys?
What didn’t Darwin know? [genetics, and so on.]
o DNA, genes, and particulate inheritance
o Gene families (for example, globins) and evolution
o Chromosomal changes in humans and apes
How did Darwin’s work change the world?
“Modern synthesis” of (roughly) Darwinian evolution and Mendelian genetics
Neo-Darwinism
Social Darwinism
What is/are the unit(s) of selection? (gene, organism, group)
Evidence for evolution*
o Fossils/paleontology
o Selective breeding of plants/animals
o Comparative anatomy: homology, vestigial features, and so on.
o Embryology/development
o Molecular biology: chromosomes, genes, and so on.
o Biogeography
What would constitute valid empirical evidence against evolution?
Human exceptionalism: what makes our species special?
o Are humans still subject to evolutionary pressures?
o Genetic vs cultural (memetic) evolution
Much more about evolution to come, throughout every aspect of course
