As a dog, I find some human behaviour a bit odd. The way they kiss, for example. New research reveals why humans kiss. It is actually a way of sniffing out a good partner.

Female humans are more attracted to males who are not closely related to them. This makes sense, it is a good breeding strategy. Humans have much lesser sense of smell than dogs have, but they have some. By coming really close, they can sense the smell, and are close enough to kiss.

Interestingly enough, couples of all human societies do not kiss each other on the mouth. This seem to be a cultural thing, rather than a genetic trait. Not even half of humans do this.

Ot os always interesting to learn new things about humans.
