Evolution
Species originate through adaptation by natural selection. Strange thing really, Darwin didn't even believe in evolution.

Adaptation and Species.
The Red Queen's Hypothesis was proposed by Leigh Van Valen in 1973 as a way to explain the coevolutionary dynamics between species where constant adaptation is necessary to maintain relative fitness.
co adaptation
A species becoming dependent on another species .
Adaptation (I'm studying the same thing ;)
aids in the dispersal of the species
one is the borrowing adaptation
Variations in traits within a species originate from genetic mutations, environmental factors, and natural selection.
One mechanism is an "adaptive radiation" of one or more species into enter an area. These origin species over time reproduce and produce mutations. Given sufficient time these mutations may result in new and subspecies.by generations of adaptation from one generation to the next.
