Artificial selection is the only kind of selection that can occur in a laboratory.
Artificial selection is selection by humans rather than the environment.
Artificial selection changes traits but not genes.
Artificial selection can occur over one or two generations as opposed to many generations.

The development of traits that organisms need in order to become more complex.
Gene changes in populations over many generations.
The change that occurs in individuals as they try to survive in their environment.
The steps by which the first life was created on Earth from random molecules.
Using artificial selection to produce different breeds of dogs
Exposing a population of rapidly replicating organisms to selection that kills a large percentage over the course of many generations, and then comparing the final generation to a population that was not exposed to the variable.
Observing a group of rapidly replicating organisms for many generations, and seeing if there was any change in their genes relative to the original population.
Introducing chimpanzees to different social settings in order to see how their behavior can be changed
It is relatively common for scientists to discover new or fossil organisms that are completely different from other organisms.
Most species that have existed on Earth are alive today.
There is uncertainty about the diversity within various species.
Scientists generally agree that most species have been identified.
Normally, biological races will evolve into separate species as time goes on.
Biological races can maintain their separate identities even if gene flow occurs frequently between them.
Biological races can be classified as more advanced and less advanced varieties.
Biological races form, similar to biological species, by restricting gene flow among groups.
the selection pressure that led to the divergence of a common ancestor into modern species
the precise time period during which organisms lived
relationships among species
geographic ranges of certain organisms
The genes in a species are only part of a universal gene pool that encompasses all species.
The gene pool is different in different individuals of the same species.
Every individual of a species carries part of the gene pool for that species in its chromosomes.
Every individual of a species carries the whole gene pool for that species in its chromosomes.
The fossil record provides substantial evidence that humans and chimps share a common ancestor.
Radiometric dating methods show that Earth is billions of years old.
Many genes found in humans are also found in yeast and they perform the same function in yeast that they do in humans.
The fossil record provides copious unequivocal evidence that the species that inhabit Earth have changed dramatically over time.
Fruit flies have a much shorter generation time than birds.
Fruit flies are smaller than birds.
Fruit flies have a simpler diet than birds.
Fruit flies don't live as long as birds.
