A(n) clock uses differences in DNA to determine when organisms diverged from a common ancestor.

Select all that applySelect all of the following that are true about molecular clocks.Multiple select question.They use the mutation rate of genes to determine the time of divergence from a common ancestor.They can be used to predict when new species are going to form in the future.They can be used to estimate when humans and chimps diverged from a common ancestor.They can be used in absolute dating of fossils.

Two species diverged from a common ancestor 2 mya based on fossil evidence. There are 10 amino acid differences in their hemoglobin molecules. We are interested in when 2 other related species diverged from a common ancestor. We don’t have any fossil evidence to help us but we do know that the 2 species have 20 amino acids different between them. According to the molecular clock, how many mya did these 2 species have a common ancestor?Group of answer choices1mya2 mya4 mya8 mya
