Speciation

Question 1

changes in gene frequency and physical traits; takes less time.

Answer 1

Question 2

large scale evolutionary changes significant enough to warrant the classification of groups; takes millions of years.

Answer 2

Macroevolution

Question 3

a population whose members can bred freely in nature and produce offspring.

Answer 3

Species

Question 4

when a population is split into two or more isolated groups by a “geological barrier”
-split populations become so distinct that they are unable to interbreed

Answer 4

Allopatric Speciation

Question 5

many varieties of the same species living in the same area at the same time
-each variation adapts to reduce competition

Answer 5

Sympatric Speciation

Question 6

ancestral population and new population are completely separate

Answer 6

Allopatric Speciation

Question 7

Answer 7

Sympatric Speciation
