Abstract

Molecules such as proteins and DNA evolve over time as a consequence of the fixation of mutations to DNA. Molecular evolution has been shown to be approximately constant across species, a phenomenon known as the molecular clock.

Keywords:

  • rate of molecular evolution;
  • evolutionary history;
  • DNA;
  • protein
