Multple Breasts...Future evolution, or not?

So randomly enough, me and Karolina talked about My dog mary`s hormonal inbalance, she has breasts as if she would have puppies tonight.

Then we started talking about What it would look like if we humans had multiple breasts, like dogs, 6 of them.
Thinking about the now rather common happenings of people having 5 kids or more!
It wouldnt really be surprising if people started to get born with more than 2 breasts, as a matter of fact there are people who have 3 breasts, and the statistics say that "decease" is more common.

Perhaps this is not a desease but a new evolutionary change in the bodies of humans, more developed than other, to the more common birth of 5 or more children.

Random but rather interessting discussions now on the brink of night.

Yours truly
