Module D Unit 2 Lesson 3 Speciation and Extinction

TermDefinition
Species is a group of individuals that can reproduce successfully in nature.
Speciation occurs when two or more populations no longer successfully reproduce. It requires a barrier to reproduction, which stops the flow of genes between populations.
Reproductively Isolated when populations are unable to reproduce with each other, geographic barriers is an example of how this may occur.
Minimum Viable Population is the smallest number of individuals needed for a population to survive for more than 40 generations given current environmental conditions.
Genome an organism's complete set of DNA, including all of its genes.
Ecosystem a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system.
