Term
Gloger's rule
Definition
Within the same species there is a tendency for the more heavily pigmented populations to be located near the equator and the lighter populations farther from the equator. 
Term
Nasal index
Definition

Width of nose/height * 100

Low values associated with cold climates

Narrow noses better at warming air than wider noses

Allen's rule
Definition

Mammal's in cold climates have short, bulky limbs; this minimizes heat loss.

Mammals in hot climates have long, slender limbs; this maximizes heat loss.

Term
Bergman's rule (2) 
Definition
Among mammals of similar size, the mammal with a linear shape loses heat more rapidly than the mammal with a nonlinear shape. 
Term
Bergman's rule (1)
Definition
Among mammals of similar shape, the larger mammal loses heat less rapidly than the smaller mammal. 
Term
adaptation
Definition
genetic changes that increase an individual's chances at reproduction or survival.
Term

Definition
short-term changes in physiology in response to new environmental conditions.
Term
adaptability
Definition

ability of an organism to make positive anatomical or physiological changes after exposure to stressfull environmental conditions

*occurs after a lifetime of exposure to environmental condition*

Term
polymorphisms
Definition
a stable polymorphism in a population which natural selection prevents alternate phenotypes from becoming fixed or lost.
Term
phylogeny 
Definition
evolutionary tree reflecting relatedness and divergence of taxonomic groups.

2) examine genes themselves

Term
cline
Definition

distribution of a trait across geographic space 

*fixed when no longer polymorphic 

Term
