Natural Selection - A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits , Evolution - Change in a kind of organism over time, Speciation - A process typically caused by the genetic isolation from a main population resulting in a new genetically distinct species, Charles Darwin - English Scientist who formulated a theory of evolution by natural selection, Selective breeding - Selection by humans for breeding of useful traits from the natural variation among different organisms , Beneficial Mutation - Any change to the genetic code that results in noticeable physiological changes that are of benefit to the organism, Harmful Mutation - Is a mutation that decreases the fitness of the organism, Homologous Structure - Structures that have a different forms in different organisms but develop from the same general structure, Analagous Structure - Similar function but different structure, Vestigial Structure - A structure that is present in an organism but no longer serves its original purpose, Survival of fittest - Process by which individuals that are better suited to their environment survive and reproduce most successfully , Adaption - A characteristic that improves an individuals ability to survive and reproduce in a particular environment, Embryology - Similarity in the appearance of embryos from different animal species that supports idea of common ancestors, Fossil evidence - The fossil record provides snapshots of the past that when assembled illustrate a panorama of evolutionary change over the past four billion years. The picture may be smudged in places and may have bits missing but fossil evidence clearly shows that life is old and has changed over time, Camouflage - Many animals have evolved to exhibit some form of camouflage which is an adaption that allows animals to blend in with certain aspects of their environment, Law of superposition - The top rock layer and its fossils is the youngest and the bottom is the oldest, Extinction - a term that typically describes a species that no longer has any known living individual,
