Darwin Theory of Evolution
Similar species being spread across continents but filling similar environmental roles.
Geographic distribution
the collection of bones used by Darwin to study evolution from a common ancestor
fossil record
individuals of a species all living in the same area
population
the two name system used in classification
binomial nomenclature
fossil made of tracks left by animals
trace fossil
The idea that evolutionary change takes a long time
Gradualism
Structures that are similar and show relatedness in species
Homologous structures
the collection of all genes and their variants in a population of organisms that can reproduce
gene pool
three domains
eukarya, eubacteria, archaebacteria
using half lives of radioactive isotopes to date items
radiometric dating
What scientist believed that species were working towards perfection?
Lamarck
Structures that are similar but don't show relatedness in species
analogous structures
mutations, lateral gene transfer, and genetic recombination are all examples of
genetic variation
Looks at a group of species
in the lens of a common
ancestor
cladogram
dated the earth using the rate of salt addition to the ocean
John Joly
The point when food required exceeds food available
Malthus trap
Early stage development that can be observed to show relatedness
embryology
Individuals at one end of the curve have
higher fitness than individuals at any
other point of the curve
directional selection
a way of organizing living things into a hierarchy of categories.
Linnaean classification
Developed the continental drift theory
Alfred Wegner
A white rabbit is more likely to live in a snowy environment and produce offspring than a brown rabbit. This is an example of?
Natural selection
body parts that appear to have no current function but are remnants of past ancestors.
vestigial structures
Allele frequencies change
because of the migration of
a small subgroup of a
population
founder effect
the six kingdoms
plantae, animalia, protista, eubacteria, archaebacteria, fungi
extinction that occurs outside of mass extinction events
background extinction
