What is Evolution?
The process by which traits survive in a population because they increase fitness or suitedness of organisms.
What is natural selection?
Development of a trait that increases survival is known as what?
What is adaptation?
These are the non-living parts of the environment that organisms need to survive.
What are abiotic factors?
These are structures that no longer serve a purpose.
What is vestigial?
When organisms produce far more offspring than can survive.
What is overproduction?
There are two cheetahs.
CHEETAH A. One runs at 30 mph, but manages to survive long enough to reproduce.

Which statement best describes a current understanding of natural selection?
(1) Natural selection influences the frequency of an adaptation in a population.
(2) Natural selection has been discarded as an important concept in evolution.
(3) Changes in gene frequencies due to natural selection have little effect on the evolution of species.
(4) New mutations of genetic material are due to natural selection.
What is Choice 1?
