Thomas Kuhn
Wrote, The origin of Species. Presented two revolutionary ideas. Realized that we descended from previously existing species, and species and their environments are a study of natural selection
Charles Darwin
a gradual process in which forms that are better suited to their environment increase in frequency over long periods of time.
natural selection
wrote “ nothing in biology makes sense except in the light of evolution” because of Darwins theory
Dobzhansky
CHANGE over time
change in allele frequency
mutations lead to changes in phenotype
evolution
changes in the DNA sequence
sometimes mutations can be good and change fitness for the better. most times this doesn’t happen
the result is evolutionary change by selection
mutations
observable measurable characteristics of organisms
phenotype
major transitions
the evolution of the prokaryotic cell, evolution of eukaryotic cell, evolution of multicellularty
naming of organisms
taxonomy
evolutionary history
phylogeny
