What makes us different from all the other animals? Is it our swollen brains, our idle hands, or perhaps our limber thumbs? In 2011, a research team reviewed the quirks of human DNA and came across another oddly shaped appendage that makes us who we are: I mean, of course, man’s smooth and spineless member. The penises of lots of mammals are endowed with “horny papillae,” hardened bumps or spikes that sometimes look like rows of studs on a fancy condom. These papillae enhance sensation, or so it has been claimed, and shorten a mating male’s delay to climax. Since humans lost their phallic bumps several million years ago, it could be that we evolved to take it slow. And it could also be the case that longer-lasting sex produced more intimate relationships.

    The question should be how are we similar to other animals, and on that question I could say from plain everyday observations that we fly like the birds swim like whales and run like ancients bipeds.  And if the case is that we do share more with the animal kingdom much more than just our reptile brain as some scientists claim then that would mean those animals that we branched from should at some point show themselves in human form.  For instance I’m assuming that if somewhere down the line we had bird blood we would get noses that look like beaks, and hair that would feel like a spider’s silk, etc. 
    I believe we are both monogamous and polygamous depending on which secondary animal charectaristics might dominant, but what do I know….
