Definition of vestigial organ.
What is an organ that that serves no useful function in an organism?
200
When the members of two populations that cannot interbreed and produce fertile offspring.
What is reproductive isolation?
200
The number of times an allele occurs in a gene pool compared with the number of times other alleles occur.
What is relative frequency?
200
The process of when a single species or a small group of species has evolved,through natural selection and other processes.
What is adaptive radiation?
300
Three types of organisms that Darwin documented using adaptive radiation.
What are Iguanas, Tortoises, and Finches?
300
The name of the principle that states that each living species has descended,with changes,from other species over time
What is descent with modification?
300
The Albert squirrel lives in the Southwest.About 10,000 years ago,the Colorado River split the species into two separate populations. Two separate pools form. Genetic changes that appeared in one group,but did not pass to the other.
This isolating mechanism is called...
What is geographic isolation?
300
Definition of founder effect.
What is a situation in which allele frequencies change as a result of the migration of a small subgroup or population?

The presence of a vestigial organ may not affect an organism's ability to survive and reproduce.
Why would an organism possess organs with little or no function?
400
The process that caused the finches beak's size and shape to change in the Galapagos Islands.
What is natural selection?
400
Three ways natural selection can affect the distribution of phenotypes.

What are two explanations for the rate of evolution?
500
Idea that influenced Darwin's theory "organisms produce more offspring than can survive, and many that do survive compete for limited resources"
What is the struggle for existence?

The reason that similar embryos are used as evidence for evolution.
What is to show how species come from common ancestors?
500
Formation that could happen because of ecological competition.
What is speciation?
500
Reasoned that if the human population continued to grow unchecked, sooner or later, there would be insufficient living space and food for everyone.
