theory of evolution
the scientist that made the theory of evolution
who is Charles Darwin?
study of similarities and differences in structures of different species
what is comparative anatomy?
when a population has evolved in a short period of time
what is microevolution?
the number of specific species in a given area
what is a population?
when new species evolve
what is speciation?
humans can breed plants and animals to have good traits
what is artificial selection?
similar inherited traits from a common ancestor
what are homologous structures?
when a population evolves over many generations of microevolutions
what is a macroevolution?
science that focuses on the evolution within a population
what is population genetics?
geologic and climate conditions are stable
what is gradualism?
French naturalist who believed in inheritance of characteristics
who is Jean Baptiste Lamarck?
structures that work in a similar way in unrelated organisms
what are analogous structures?
a variation in the alleles of a population
what is a mutation?
all the genes of all the members of a population
what is a gene pool?
new species without geographic separation don't interbreed
what is sympatric speciation?
English geologist who believed that earth is much older than people thought at the time
who is Charles Lyell?
study of the similarities and differences in embryos
what is comparative embryology?
when individuals move in and out of a gene pool
what is gene flow?
this shows how many alleles are found in the population
what is allele frequency?
species in symbiotic relationships tend to evolve together
what is coevolution?
English economist who believed that the human population is growing to fast for the amount of resources there is
who is Thomas Malthus?
structures that are no longer needed in an organism
what are vestigial structures?
random changes that happen in small populations including the bottleneck effect and founder effect
what is genetic drift?
alleles in a population don't change if: no mutations occur, no migration occurs, no natural selection occurs, there is a large population and mating is random.
what is the Hardy-Weinburg Therom?
conditions are changing and evolution happens more quickly
what is punctuated equilibrium?
