Question

1) Matching.

In evolution,
evolve,
do not.



2) Choose the best answer.

A group of individuals of the same species living in the same location is a _________.

mutation

gradualism

population

genetic drift



3) Choose the best answer.

A ________ is a change in the DNA that makes up genes.

population

mutation

genetic drift

speciation



4) Match the correct term for each definition below.

a species' or population's entire group of alleles
the changing frequency of an allele occurring in a population over time
when an individual from one population is introduced to another population



5) Choose the best answer.

The results of genetic drift are more apparent in ______________ populations.

small

big

ancient

moving



6) Matching.

Gene
between two populations will be
if a physical
is present.



7) Choose the best answer.

The process of forming a new species from an existing species is _____.

gene flow

speciation

population

genetic drift



8) Matching.

is evolution within a
, while
is the
of one type of organism to another type of organism.



9) Matching.

For speciation to occur, populations must develop enough
changes so that successful
and producing of
becomes impossible.



10) Match the correct term for each definition below.

an evolutionary theory that states all evolution is slow and proceeds at a steady rate over a long period of time
an evolutionary theory that states that evolution is characterized by long periods without change, interrupted, or punctuated, by periods of rapid change.

Answer 1

1) In evolution, populations evolve; individuals do not.

2) population

3) mutation

4) a species' or population's entire group of alleles — gene pool
the changing frequency of an allele occurring in a population over time — evolution (change in allele frequency / microevolution)
when an individual from one population is introduced to another population — gene flow (migration)

5) small

6) Gene flow between two populations will be limited/reduced if a physical barrier is present.

7) speciation

8) Microevolution is evolution within a species, while macroevolution is the evolution of one type of organism to another type of organism.

9) For speciation to occur, populations must develop enough genetic changes so that successful mating (interbreeding) and producing of fertile offspring becomes impossible.

10) an evolutionary theory that states all evolution is slow and proceeds at a steady rate over a long period of time — gradualism
an evolutionary theory that states that evolution is characterized by long periods without change, interrupted, or punctuated, by periods of rapid change — punctuated equilibrium
