Isolation and Gradualism
... Geographic Isolation- favors speciation by segregating a small group from the main population. Changes in gene frequency are more likely to occur in a small population. In time, this isolated population may evolve into a separate species due to: Different initial gene frequencies than the main pop ...

Organisms at high altitude
.jpg?width=300)
Organisms can live at high altitude, either on land, or while flying. Decreased oxygen availability and decreased temperature make life at high altitude challenging. Despite these environmental conditions, many species have been successfully adapted at high altitudes. Animals have developed physiological adaptations to enhance oxygen uptake and delivery to tissues which can be used to sustain metabolism. The strategies used by animals to adapt to high altitude depend on their morphology and phylogeny.
