What is the common ancestor of rats and mice?
Phylogenetic and palaeontological data suggest that mice and rats diverged apart from a common ancestor 10-15 myr BP (Jaeger et al., 1986), and by 6 myr BP, the genus Mus was established.
Are mice and rats related?
Rats and mice are both rodents, so look similar – the biggest difference is their size. Rats are larger and heavier while mice have smaller slender bodies. Mice also have long slender tails (for their body size) covered in hair compared to rat tails which are shorter, thicker and hairless.

Are humans descended from rodents?
The genome analysis, by 20 institutions from six countries, showed that humans, rats and mice have about the same number of genes. It also reveals that humans and rodents went our separate ways from a common ancestor about 80 million years ago, with rats and mice diverging between 12 and 24 million years ago.
Are rats more intelligent than mice?
Mice were long thought to be less intelligent than rats, but recent research is proving this assumption to be incorrect. In fact, studies are indicating that mice have many of the same decision-making abilities as rats.
