Why we are attracted to certain people of the opposite sex?
There’s a reason why we are attracted to certain people of the opposite sex.  According to evolutionary psychology, what we want is healthy mates.  Beauty, for example, is a way in which we have of judging the health of another person.  The theory says, for example, that if you are at a bar on Friday night and you want to “pick up” somebody rapidly, you can’t do a blood test.  You can’t do a physical examination to find out how healthy that person is, so you need markers. 

According to evolutionary psychology, the markers are for estrogen and testosterone - shown in the body by beauty and physical health.  For example, estrogen has estrogen markers: large eyes, small chin and thick lips. Same thing with testosterone: testosterone makes large necks and strong jaws and a lower voice. That also means the person is fit; the person is healthy. These are markers that we use.

New role found for the immune system: Controlling Social Interactions
In a startling discovery that raises fundamental questions about human behavior, researchers at the University of Virginia School of Medicine have determined that the immune system directly affects – and even controls – creatures’ social behavior, such as their desire to interact with others.

So could immune system problems contribute to an inability to have normal social interactions? The answer appears to be yes, and that finding could have significant implications for neurological diseases such as autism-spectrum disorders and schizophrenia.

“The brain and the adaptive immune system were thought to be isolated from each other, and any immune activity in the brain was perceived as sign of a pathology. And now, not only are we showing that they are closely interacting, but some of our behavior traits might have evolved because of our immune response to pathogens,” explained Jonathan Kipnis, chair of UVA’s Department of Neuroscience.

“It’s crazy, but maybe we are just multicellular battlefields for two ancient forces: pathogens and the immune system. Part of our personality may actually be dictated by the immune system.”
