Answer 0

Micro evolution

Question 1

The development of a new species

Answer 1

Speciation

Question 2

Made up by microevolution

The overall pattern of relationships among all organisms

Answer 2

Macroevolution

Question 3

Group of populations that can reproduce with each other and produce viable, fertile offspring

Answer 3

Species

Question 4

The five barriers that prevent members of two different species from producing a hybrid zygote

Answer 4

Habitat isolation
Temporal isolation
Behavioral isolation
Mechanical isolation
Gametic isolation

Question 5

Is reproductive isolation the only way to define different species?

Answer 5

No

Question 6

Physically separated speciation

Answer 6

Allopatric

Question 7

Together in the same location

Speciation without physical separation

Answer 7

Sympatric

Question 8

New species can arise when cell division errors or hybridization result in a change in the number of __ that a new individual has

Answer 8

Chromosomes

Question 9

New species appears suddenly in the fossil record then stays basically the same for a long time

Answer 9

Punctuated equilibrium

Question 10

Does a punctuated equilibrium indicate that the new species arose instantaneously

Answer 10

No because suddenly is a relative term- it actually took thousands of years

Question 11

An example of how a change in a single gene can create the reproductive isolation that leads to speciation

Answer 11
