What is one difference between natural selection and selective breeding?
With natural selection, the genetic makeup of an organism is different than it's parents. With selective breeding the genetic makeup is identical to its' parent.
Once a trait helps a species survive, the time it takes for that trait to become apart of the population is much faster with natural selection.
Natural selection can only occur when organisms are chosen and produce offspring. Selective breeding allows organisms to select a mate who is the best adapted to its' environment.
Traits developed through natural selection are influenced by pressures from the environment. Organisms that are produced through selective breeding have traits selected by humans that may or may not be related to environmental pressures.
