The mammal mentioned in the article was a marsupial, so not in our ancestral line. Marsupials have split from the eutherians (to which we belong) long before the C-T boundary. At C-T there were already early primates, which is our closer family. A fascinating story about this is in Baxter's "Evolution" book which starts with a little primate at the CT boundary and traces the history of the family to modern humans. |
