When the idea of a constant molecular clock first emerged, it was thought that the predominant evolutionary force underlying amino acid or nucleotide substitutions was natural selection.

each one containing one strand it inherited from the original molecule and one newly-formed strand. Often this copying process makes errors, so that the wrong nucleotide is placed in position.
