Therefore, the green light period for other phases should be resplit. Correspondingly, three commonly used ways to achieve this include the distribution of all the increased red-light times to a certain phase [31,32], distribution of the increased red-light period to subsequent phases according to the phase splits [33], and the resplitting of the green light period according to the degree of saturation.
The traditional method B is the method which resplits the green light time period according to the degree of saturation.
The dawn of primates has been hard to figure out, Murphy says, because big lineages have split and
resplit so fast, from an evolutionary standpoint, that branches had little time to accumulate telltale differences before splintering further.
