I want to know the answer to the following question:
Through Molecular studies, what was used to suggest new relationships among mammal families?
All the background I'm provided with is that "Classification systems based on molecular studies reveal three major groups or lineages of placental mammals- Afrotheria, Xenarthra, and Boreoeutheria- which diverged from early common ancestors in the Cretaceous.". Is that enough to answer the question?
