  3. Evolution • The process by which living things have changed over time

  4. Extinct Species • a species that no longer exists anywhere on earth

  5. Classification/Taxonomy • biological classification is a system which is used to organize and codify all life on Earth.

  6. Natural Selection • the process by which forms of life having traits that better enable them to adapt to specific environmental pressures.

  7. Speciation • the formation of new species as a result of geographic, physiological, anatomical, or behavioral factors that prevent previously interbreeding populations from breeding with each other.

  8. Adaptation • when an organism becomes better fitted to survive and multiply in its environment.

  9. DNA - deoxyribonucleic acid • an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms

  10. Genetic Diversity • the level of biodiversity, refers to the total number of genetic characteristics in the genetic makeup of a species.

  11. Phenotype • is an organisms observable characteristics which are influenced both by its genotype and by the environment.

  12. Genotype • is the set of genes that an organism carries.

  13. Niche • includes both the animals or plants physical habitat and how it has adapted to life in that habitat.

  14. Mutation • A mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene.

  15. Gene • A segment of DNA that codes for a particular protein.

  16. Gene Pool • All the genes of all the members in a population.

  17. Selective Pressure • Any environmental factor that favors one trait over another.

  18. Species • Any group of organisms, the members of which successfully breed with each other, producing healthy, fertile offspring.

  19. Genetic Isolation • What occurs when two groups of one species are prevented from breeding with each other.

  20. Inherited Trait • An inherited characteristic—such as hair and eye color or muscle and bone structure—that has been passed on from a previous generation.

  21. Acquired Trait • An acquired characteristic—such as the ability to ride a bike or do karate—that is attained throughout life. Acquired traits are not passed on genetically.
