Aristotle's Scala Naturae

organisms existed on stair step and never changed

Alexander von Humboldt

ecosystems far apart are similar

Charles Lyell

geology and timescale; slow processes accumulate over a long time and we can see that through examples like grand canyon

Mary Anning

John Edmonstone

worked with museum teaching college students how to perform taxidermy, taught Charles Darwin taxidermy

Charles Darwin

performed lots of dove breeding experiments, used one dove but created different looking doves, asked “how do you get phenotypes out of this parent”; took different doves, mated them, and found parent dove (essentially inheritance and breeding pattern and environmental factors change things)

Habitat/Ecosystem

groupings of species by physical environment

higher taxa/functional groups

groupings of species by evolutionary relatedness or ecological role

species

different species occupying the same habitat at the same time

genetic

differences in genotypes of individuals of the same species

plasticity

different phenotypes among individuals with the same genotype

biodiversity “hotspots”

places w many species that are endemic (occur in no other regions)

wallace’s line

no species crossed line (bridge) of land because of ocean in between

weather

temperature and precipitation over a short period of time (days to weeks)

Climate

average and seasonal pattern of temperature and precipitation over longer periods of time (years and longer)
