Natural Selection – The mechanism of evolution by which the environment acts on populations to enhance the adaptive ability and reproductive success of individuals possessing desirable genetic variants, increasing the chance that those beneficial traits will predominate in succeeding generations.
Neanderthals – A population of extinct hominids, whose lineage extends back from 24,000 years to 200,000 years ago.
Nebraska Man – Fossil remains of an extinct prehuman found in 1927, later proven to be an extinct pig.
Negative selection - The process of weeding out harmful alleles from a gene pool by natural selection.
Neolithic Era (New Stone Age) - A period that began about 10,000 years ago with the spread of agricultural villages through the Middle East and Central and South America.
Nucleotides – Chemical compounds that make up DNA.
