The difference between the two is that natural selection happens naturally but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.
WebNatural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes). Natural selection on traits … WebMany German biologists conceived of life evolving according to predetermined rules, in the same way an embryo develops in the womb. But in the mid-1800s, Darwin and the British biologist Alfred Russel Wallace independently conceived of a natural, even observable, way for life to change: a process Darwin called natural selection.
