After which event could you say evolution has occurred?

Allele frequency changes in a population
Which group of organisms is considered a population?
freshwater salmon
all the deer in North America
all the birds living in the rain forest
a flock of sheep living on the same farm
Type of natural selection that disrupts the population average by favoring the extreme traits
Disruptive Selection
Stabilizing Selection
Directional Selection
A gene pool consists of
all of the dominant alleles in a population
all of the recessive alleles in a population
all of the alleles in a population
What are vestigial structures?
Structures in different species that are similar enough to suggest the species had a common ancestor
Similar patterns of early embryonic development
Structures that appear to have no function for the organism but probably had a function in an ancestral organism
Similarities in the protein (DNA) of different organisms
What process involves the environment acting on individuals so that those with favorable traits survive and reproduce?
Evolution
Natural Selection
Genetic Drift
Gene Flow
Type of natural selection that favors the average form of a trait over extreme forms?
Stabilizing
Directional
Disruptive
Natural selection acts on variations in populations through a specific trait. Which is true?
All forms of the trait have the same impact on survival
The trait is resistant to mutations
The trait is passed on to the next generation
The trait is the same for all organisms
Introduction of new genes into a population as new organisms move in
Gene Flow (migration)
Genetic Drift
Genetic Recombination
Mutation
Which of the following must be true if the organisms in two populations are no longer considered to be the same species?
They do not resemble each other
They cannot reproduce successfully
They do not share any of the same genes
They do not share the same space
All of the following statements about Darwin are true EXCEPT for
Darwin was highly curious about the natural world
Darwin collected many specimens over his lifetime, including rocks, shells, beetles, plants, and more.
Darwin circumnavigated the world for 5 years aboard the HMS Beagle
Darwin loved learning about blood, surgeries, and medicine which is why he became a medical doctor.
Fossils are able to provide exact dates that organisms lived in the past.
True
False
