Web1 de abr. de 2003 · The concept of molecular clock studies is evaluating divergence times of lineages based on the assumption that mutations occur at balanced rate over time, and gradually become a reliable tool... WebThe molecular clock would time evolutionary events and make it possible to reconstruct phylogenetic history--the branching relationships among lineages leading to modern species. Kimura's neutrality theory postulates that rates of molecular evolution are stochastically constant and, hence, that there is a molecular clock. floral runners for hallways
