a geologist; popularized Hutton's view. His ideas were influential on
Darwin's thinking: His notion of the greater age of Earth gave more time for
gradual change in species, and the process of change provided an analogy
for this change
Ecological roles of prokaryotes include
a. nitrogen fixation
b. decomposition
c. photosynthesis
d. pathogenicity
e. all of the above

, e. all of the above
Cats on the island of Key West exhibit high rates of polydactyly (extra toes), likely due
to...
a. founder effect
b. genetic drift
c. bottleneck effect
d. natural selection
Give this one a try later!
a. founder effect
b. genetic drift
Morphological species concepts
Give this one a try later!
involves thinking about these differences in terms of how species differ in
the shapes of their bodies and otherwise what they look like (including on
the inside)
chemotroph
Give this one a try later!
organism that obtains energy from chemical compounds
,(Maximum) Parsimony
Give this one a try later!
A principle that states that when considering multiple explanations for an
observation, one should first investigate the simplest explanation that is
consistent with the facts
Events that occurred in the simplest, most obvious way
Origin of life
Give this one a try later!
Life evolved from nonliving chemical systems
alkaliphile
Give this one a try later!
organism with optimal growth pH of nine or above
Plate tectonics
Give this one a try later!
, A theory stating that the earth's surface is broken into plates that move
When sympatric speciation occurs,
a. populations become reproductively isolated within the same habitat
b. populations separate into groups that are no longer close to each other
c. historically separated species reproduce successfully
d. a geographical barrier isolates populations from each other
Give this one a try later!
a. populations become reproductively isolated within the same habitat
decomposer
Give this one a try later!
organism that carries out the decomposition of dead organisms
basal taxon
Give this one a try later!
branch on a phylogenetic tree that has not diverged significantly from the
root ancestor
