Answers
1
Allelic frequencies are unchanged, population is in genetic equilibrium. This is
Hardy-Weinberg principle
sympatric speciation
prezygotic mechanism
genetic drift
2
Long wiggly tails that look like snakes are examples of
stabilizing selection
disruptive selection
directional selection
sexual selection
3
If a species is suddenly introduced into a new habitat, what might occur?
selective speciation
habitat speciation
adaptive radiation
coevolution
4
A mule is an example of
postzygotic isolation
speciation
prezygotic isolation
allopatric speciation
5
Scientists who study the fossil record are
dramaturgists
archeologists
paleontologists
meteorologists
6
Which is NOT a condition for Hardy-Weinberg?
Gene flow
No mutation
random mating
large population size
7
When a species evolves into a new one without physical barrier is
adaptive radiation
coevolution
allopatric evolution
sympatric evolution
8
Why did it take Darwin 23 years to publish "Origin of Species?"
He was out of the country
It would be war between religion and science
It challenged everything people believed in
The King was against it
9
Best description why animal's adaptation to tropical rainforest
elephant's long neck
long neck in giraffe
migration of birds in winter
camouflage in a tree frog
10
A physical barrier lead to this type of speciation
allopatric
prezygotic
pragmatic
sympatric
11
Changes in the allele frequency in a gene pool is
genetic drift
mutation
founder effect
gene flow
12
Structures without any use, but were once in ancestral organisms are
comparative
anagolous
vistigial
homologous
13
Isolation occurring when species in same range but mate in different areas
temporal
ecological
sexual
reproductive
14
GREATEST potential for evolutionary change is
Large population, may mutations
small population, few mutations
small population, many mutations
large populations, few mutations
15
Natural selection that favours extreme traits over moderate ones
stabilizing
sexual
disruptive
directional
16
A population declines to a low level, then rebounds is
Bottleneck
Mutation
Genetic drift
Founder effect
17
Fossils showing intermediate characteristics between extinct and current species
informational
archeological
transactional
transitional
18
Mimicry exists between
Chameleons and geckos
owls and eagles
crows and ravens
king snakes and coral snakes
19
Species separated by incompatible reproductive genitalia is
prezygotic isolation
reproductive isolation
mechanical isolation
post-zygotic isolation
20
Not available to Darwin but are now compelling evidence of evolution
genetics
DNA
fossils
microscopes
