macroevolution
what is speciation
when new species evolve
what are the people who study fossils
paleontolgist
What theory did Darwin create
the theory of evolution
What are acquired characteristics
non-heritable traits devolped in an orangisms lifetime
what is the gene pool
the total genes in a population
what is allopatric separation
When species are geographically separated
what are analogus structure
silmair traits in organisms with common ancestors
What did Darwin discover about the finches on different islands
They were completely different species
What is the main way to get an acquired characteristic
injuries
what is genetic flow
when members of the population go out or in a population
what is sympatric separation
new species without geographic seperation
what are homologus structure
Silmair inherited traits from a common ancestor
What islands did darwin do his discovers on
the galaopogos
what is natural selection
when the enoviorment change and some die and others live making the ones that live pass on there genes
What is genetic drift
a change in the allies due to random chance
what is coevolation
when two species evole togather
what do fossils show
changes overtime in animals
What did Darwin find on the islands
new species
What is artificial selection
When humans pick traits they want from animals and breed the animals with those traits
what is a common ancestor
it the last organism to species evolved from before they separated
what is equallibrim
when climate is changing, and conditions are changing
What are vestigial structures
traits in species that have lost there porpuse
What ship did Darwin take to the islands
The HMS Beagle
What do acquired characteristics do
They change the phenotype
What is the name of the last universal common ancestor
