East to west lines that indicate north to south position on the globe.

Question 2

Longitude

Answer 2

Question 3

Biological Species Concept

Answer 3

A population or group of populations that are intermating or potentially intermating and are reproductively isolated from other groups.

Question 4

Phylogenetic Species Concept

Answer 4

A species is the smallest monophyletic group of common ancestry.

Question 5

Cohesion Species Concept

Answer 5

A species is the most inclusive population of individuals having the potential for phenotypic cohesion through intrinsic cohesive mechanisms.

Question 6

Genealogical Species Concept

Answer 6

Species are exclusive groups of organisms where an exclusive group is one whose members are all more closely related to one another than to any organism outside of the group.

Question 7

Ecological Species Concept

Answer 7

A species is a lineage that occupies an adaptive zone minimally different than that of any other lineage in its range and which evolves separately from all other lineages outside its range.

Question 8

Recognition Species Concept

Answer 8

A species is the most inclusive population of organisms that share a common fertilization system.

Question 9

Evolutionary Species Concept

Answer 9

A species is a lineage evolving separately from others and with its own unitary evolutionary roles and tendencies.

Question 10

Lineage

Answer 10

The result of divisions of taxa.

Question 11

Species

Answer 11

The end of a lineage, the terminus of each branch.

Question 12

Evolution

Answer 12

Generation to generation change in the frequency of alleles in a population and the division of populations into lineages.

Question 13

Population

Answer 13

A group of potentially interbreeding organisms living in the same place at the same time.

Question 14

Cladistics vs Phenetics

Answer 14

Cladistics and Phenetics are both methods by which organisms can be classified and grouped. However, Cladistics is the classification of organisms based upon their evolutionary history whereas Phenetics is the classification of organisms based upon morphological characteristics that are observable.
