-
DNA
(biochemistry) a long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix; associated with the transmission of genetic information

undergo development or evolution
-
fossil
the remains (or an impression) of a plant or animal that existed in a past geological age and that has been excavated from the soil
-
gene
(genetics) a segment of DNA that is involved in producing a polypeptide chain; it can include regions preceding and following the coding DNA as well as introns between the exons; it is considered a unit of heredity

microevolution
evolution resulting from small specific genetic changes that can lead to a new subspecies

mutation
a change or alteration in form or qualities
-
natural selection
a natural process resulting in the evolution of organisms best adapted to the environment

organic process
a process occurring in living organisms
-
organism
a living thing that has (or can develop) the ability to act or function independently
-
phylogenesis
(biology) the sequence of events involved in the evolutionary development of a species or taxonomic group of organisms
-
phylogeny
(biology) the sequence of events involved in the evolutionary development of a species or taxonomic group of organisms

a measure of how likely it is that some event will occur; a number expressing the ratio of favorable cases to the whole number of cases possible
-
recessive gene
gene that produces its characteristic phenotype only when its allele is identical
-
regulatory gene
a gene that produces a repressor substance that inhibits an operator gene
-
reproduction
the act of making copies
-
selection
the act of choosing or selecting
-
sequence
a following of one thing after another in time
