6
Birds of paradise are known for their extreme dances. Their dance attracts mates. This is an example of:
natural selection
gene flow
genetic drift
non-random mating
7
What are the mechanisms of evolution?
All of the above
Non-Random mating and genetic drift
Natural selection
Gene flow and Mutations
8

Mutation
Gene Flow
Natural selection
Genetic Drift
9
Non-random mating is choosing a mate based on if traits is desired.
False
True
10
Traits that give organisms an advantage in their environment are called what?
adapations
variations
accumations
accommodations
11
With 'Genetic Drift' traits become dominant due to:
chance
strength
selection
adaptations
12
What best fits the theory of Natural Selection?
Adaptations that are passed on to offspring.
Animals better adapted to environment, survive and reproduce
A feature used more is stronger. One not used disappears.
Features that enable survival in a habitat
13
How did this animal's teeth get so big?
His teeth grew bigger because his mom brushed them
I dont know but that guy sure looks like Mr. Maher
Bigger teeth allowed his ancestors to be more fit

mutations
natural selection
genetic enginering
genetic drift
16
The change in traits in a population over time is called
mutualism
evolution
extinction
acclimatization
17
Gene flow describes the
the movement of gene from one population to the next
the movement of genes within a population
the movement of genes from one generation to the next
genetic drift
18
Mutations are a mechanism of evolution what do they do?
always help organism
cause fitness
introduce variation
always create adaptations
19
Do mutations affect a small or large population faster?
large
small
