The phylogeny below was generated using molecular data. C is the node representing the common ancestor of humans and chimpanzees; B is the node representing the common ancestor of the cow and human/chimpanzee lineages; A is the node representing the common ancestor of the salmon and cow/human/chimpanzee lineages. Imagine that a researcher is interested in finding the approximate dates of A, B, and C. Give two approaches that would help resolve the timing of the nodes in the phylogeny.
