it keeps genes in a narrow window
when a new speices evolves
what is a vestigial structure
a structure in your body that was once useful but now is no longer needed
name 2 thing in Darwin's theory of evolution

2. living things with beneficial traits produce more offspring
3. earth is very old
4. struggle for existance with population growth
5. artificial selection
6. fitness
7. natral selection
what is a recently added taxonomy
domain
what is directional selection
it is hen 2 extreme phenotypes are selected
geologic and climate conditions are stable
what is biogeography
the study of how and why plants and animals live where they do
he said that the earth is much older than people think
what does taxa mean
hieracy of grouping
what is disruptive selection
phenotypes in the middle of the range are selected for
what is micro evolution
evoulution over a short period of time
name 2 peices of evidence that Darwin used to created his theory

natrualist
what is taxonmy
the science of classifying orginisums
what is artificial selection
it is when people choose which traits get passed down
what is a gene pool
