evolution that occurs on a small scale, affecting only a single population
microevolution
Elimination of a species
extinction
Give an example of a vestigial structure
human wisdom teeth
The field of classifying organisms
taxonomy
Features that allow an organism to survive in its environment better
adaptations
two organisms change in response to each other
coevolution
Embryos of all vertebrates go through a phase where they look identical. This is evidence for evolution in which field of science?
embryology
Which two levels are used in binomial nomenclature?
genus species
The ultimate cause of genetic diversity
mutations
many new species arise from one common ancestor
divergent evolution
What can you say if two species have a lot of similarities in their DNA sequence?
they are closely related
which evolved first?
lamprey
Male elk have massive antlers that make it difficult to move, but make them more attractive to mates. This is an example of
sexual selection
Give an example of convergent evolution
insects and birds developed wings to fly
Transitional fossils have been found that link extinct species to current species. This is evidence in which field of science?
paleontology
which are most closely related?
bald eagle and alligator
Explain the difference between genetic drift and gene flow
genetic drift - random change in allele freq in a pop over time, deals wit mutations
gene flow - movement of genes in/out of pop (migration), deals with pops interacting
What type of environment does sexual repro favor? Asexual repro?
a changing environment, a stable environment
Island species most closely resemble the nearest mainland species. This is evidence for evo in which field?
biogeography
What characteristics do bald eagles and antelope share?
jaws and lungs
