Mammals rising population after dinosaurs go extinct

I found this one article at http://news.msn.com/science-technology/new-research-sheds-light-on-earth-shaking-crash-that-doomed-dinosaurs talking about how after the asteroid killed the dinosaurs, mammals started to appear more around 65 million years ago. Supposedly the first mammal to make its debut on the Earth was a shrew-like creature that was possibly bigger than a mouse. It also mentioned that over time it evolved into all of the different mammals that we have today including us. Who would have thought we would originate from this one mammal.
 Dinosaurs' extinction led to mammals' rise: A 2012 artist’s rendering provided by the American Museum of Natural History shows a small, hypothetical, placental, insect-eating mammal ancestor.
