The observation that genetic mutations in the genome appear to accumulate at constant rates across a wide diversity of taxa led to the development of
A)phylogenetic analysis.
B)cladistics.
C)molecular clocks.
D)maximum parsimony.

Question

Quizplus · Accepted Answer

The observation of constant rates of genetic mutations across taxa led to the development of molecular clocks, which rely on the assumption that mutations accumulate in a clock-like fashion and can be used to estimate evolutionary time scales. Phylogenetic analysis, cladistics, and maximum parsimony are methods for inferring evolutionary relationships but are not directly related to the observation of molecular clocks.
