Evolution is the change in the inherited traits of a population over many generations.
Variation refers to differences between organisms in a population.
Mutation the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations.
Adaptation a change or the process of change by which an organism or species becomes better suited to its environment.
Genetic Variation describes naturally occurring genetic differences among individuals of the same species.
Allele Frequency is a measurement of how common a certain allele is in a population.
Genotype the combination of inherited alleles.
Phenotype physical characteristics of an organism, such as fur color.
Natural Selection is a process by which a population’s environment determines which traits are beneficial and which are not.
Artificial Selection When beneficial traits are identified and reproduction is controlled so that these traits are passed on to offspring, people are selecting desired traits.
Estuary a partially enclosed coastal body of brackish water (mix of fresh and salt water) with one or more rivers or streams flowing into it, and with a free connection to the open sea.
