Evolutionary Adaptation
An adaptation is a feature that is common in a population
because it provides some improved function. Adaptations are well
fitted to their function and are produced by natural
selection.Adaptations can take many forms: a behavior that allows
better evasion of predators, a protein that functions better at
body temperature, or an anatomical feature that allows the organism
to access a valuable new resource all of these might be
adaptations. Many of the things that impress us most in nature are
thought to be adaptations.

the physical properties of an organism in response to genetic
mutation or to a change in the environment.This occurs at the
genetic level.BehavioralChange in the properties behavioral of an
organism in response to genetic mutation or to a change in the

Adaptation is characteristic change, which enhances the survival
and reproduction of an organism. The term refers to the process by
which an organism or members of a species becomes better suited to
their environment through change in a tract either physical or
behavioral that enhances their changes for survival and
reproduction. These changes come about as a result of environmental
change are are tied to natural selection.
2Coyote ExpansionWestern CoyoteEastern Coyote
As coyotes moved east at the beginning to middle of the 20th
century, they bred with red (Canis rufus) and eastern (Canis
lycaon) wolves. Studies into coyote genetics show wolf DNA present
in eastern populations of coyotes. Finches of the Galapagos
IslandsAn adaptive radiation is an event in which a species rapidly
diversifies, evolving different adaptations. Different factors may
trigger adaptive radiations, but each is a response to an
opportunity.A key adaptation means a organism changes to exploit a
new niche or resource.Vacated niches give rise to adaptive
radiation when there is no competition from other
species.Specialization within a species subdivides a species to
take advantage of different niches or food types.
Adaptive radiation about change with a species. They do not
become a different different organism. Birds still remain
birds.Adaptive RadiationDarwins Finches
