WebDeer certainly have drastically superior senses of smell to humans. We have a mere 7 million olfactory receptors, while whitetail deer have almost 300 million. Deer, however, have much smaller brains than we do. The deer brain is only approximately one-sixth the size of a human brain. Our brain size is key to our uniquely human abilities.
