7600636644Genetic DriftA change in the gene pool of a population due to chance11
7600636645EvolutionThe gradual change in a species over time12
7600636646Bottleneck Effecta reduction in the genetic diversity of a population caused by a reduction in its size13
7600636647MicroevolutionChange in genetic makeup of a population from generation to generation.14
7600636648Founder Effectgenetic drift that occurs after a small number of individuals colonize a new area15
7600636649MacroevolutionEvolution that gives rise to new species, genera, families, classes, or phyla16
7600636650Geographic IsolationIsolation between populations due to physical barriers17
7600636651GenesDNA segments that serve as the key functional units in hereditary transmission.18
7600636652Reproductive IsolationBarriers that impede members of two different species fro producing fertile offspring.19
7600636653GenotypeAn organism's genetic makeup, or allele combinations.20

7600636655MutationA change in a gene or chromosome.22
7600636656Sympatric SpeciationThe formation of new species in populations that live in the same geographic area.23
7600636657Recombinationthe rearrangement of genetic material, especially by crossing over in chromosomes or by the artificial joining of segments of DNA from different organisms24
7600873743Niche Generalistsa species that can live under a wide range of abiotic or biotic conditions25
7600873744Niche Specialistsorganisms which live in a specific habitat or feed on a small group of species26
7600873745Fossilsthe remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock27
7600873746Mass Extinctionevent in which many types of species become extinct over a short period of time28
7600873747Sixth Mass Extinctioncurrent mass extinction that is possible in this time period29
7600873748Genetic EngineeringThe direct manipulation of genes for practical purposes.30
7600873749Genetically Modified Organismsgenes from the DNA of one species are extracted and artificially forced into the genes of an unrelated plant or animal31
7600873750Range of Tolerancethe limits to the abiotic conditions that a species can tolerate32
7600873751Fundamental Nichethe entire set of conditions under which an animal (population, species) can survive and reproduce itself33
7600873752Realized Nichethe set of conditions actually used by given animal (pop, species), after interactions with other species (predation and especially competition) have been taken into account34
