Along the way, mammals began to lose all the extra receptors until only two remained. Sign up now to make sure you’re up to date on the latest happenings! People have three types of cones, while dogs have two. It was only later on that some primates, including humans, re-evolved and added the additional receptor that gives us full color vision. A poodle, for example, is estimated to have what we would call 20/75 vision in the US (about 6/24 elsewhere in the world). Humans have 6 million cone cells compared to the 1.2 million that dogs have.
