Start Quiz
1.

Evolution by natural selection results in

identical populations
a change in allele frequency in a population over time
no change
changes in individuals
2.

Reproductive isolation can lead to

gene flow
speciation
reduced variation only
cloning
3.

Allopatric speciation involves

geographical isolation of populations
populations in the same place
polyploidy only
no selection
4.

Sympatric speciation occurs when

a river divides a population
populations become reproductively isolated without geographical separation
islands form
mountains rise
5.

DNA and protein comparisons (genomics and proteomics) support evolution because

all species have identical DNA
proteins never change
DNA is not inherited
closely related species have more similar sequences
6.

New scientific evidence is validated by

advertising
government decree
peer review, publication in journals and conferences
popular vote
7.

A new allele arises by

mutation
natural selection
gene flow
isolation
8.

Which is a mechanism of reproductive isolation?

Different breeding seasons
Sharing the same habitat
Identical courtship
Gene flow
9.

Organisms better adapted to their environment are more likely to

survive, reproduce and pass on their advantageous alleles
mutate
migrate
die
10.

DNA molecular evidence led to the classification of organisms into

two kingdoms
three domains
five species
