STROKE ME, I'M A PRIMATE

I PROMISE NOT TO SUE

In a second report from the Pop!Tech 2007 conference in Maine, Evgeny Morozov discovers that after 40 million years of evolution we should be more enthusiastic about touching each other in public ...

Dr. Nina Jablonski,
a primatologist, evolutionary biologist, and paleontologist, is professor
and head of anthropology at Pennsylvania State University. She kicks off Saturday at Pop!Tech with a talk on the meaning of
human skin, the subject of her book, “Skin: A Natural History“.

She starts by noting what “a phenomenal
and exceptional group of primates” she has for an audience. She
asks each of us to look to his or her neighbour, and touch for about 20 seconds. She suspects that some of us haven't done much touching this
morning; she worries that we are too wired, surrounded by our cell
phones and technology to even think about the great emotional power of
the human touch. She says that we’ve lost the capacity to observe each
other, and wishes for a return of times when we did more things of this
kind.

We primates are highly observant animals, she says. It's in our nature to touch each another, inspect each other, learn through observation. Our main sense, the sense which we depend on most for our information gathering, may be vision, but the second is touch, equal with hearing.

Our great touch-organ, the skin, helps us gather an enormous amount of information
from and about our environment. Some of our most
sensitive skin is on our hands, equipped with nerves that detect
pain, touch and temperature. Jablonski shows a picture of a cartoonish creature she
calls “the human sensory homunculus”, whose body parts are proportional
to their skin sensitivity. Hands are
the biggest part of the body; lips and tongue also quite come close.

As primates, our instinct is to touch one another quite a lot, she says. From the moment of birth all primates start to engage in very detailed types of
touching with their mothers. She cites an experiment from the early 1960s, conducted by a psychologist called Harry Harlow, who took baby monkeys away from their mothers
and put them next to two mechanical surrogate mothers. One "mother" was soft,
had some sort of a pillow attached to it, but had no milk. The other
was made up of wires only, but it did have milk. The baby monkeys spent
all of their time with the “milkless mother”, and made only very short
trips to the wired one to get fed. The reassurance and warmth of the
“milkless mother” was more important.

There are other ways in which primates use touch. One of
them is to to cement alliances. Jablonski presents a picture of two
chimpanzees who are touching each other trying to patch things up and
get over their arguments.

Grooming is incredibly soothing, says Jablonski. The
participating animals both gain a tremendous amount of relaxation. Their
levels of stress hormone both decline. We humans pay a lot for grooming, although we may not call it such: think of the spa massages and facials given to us by
complete strangers.

Jablonski observes that when we touched each other just now, at her request, we must have noticed
differences in one another’s skin colour, from very light to very
dark. This is a function of the skin pigment, melanin, of which we have different amounts. She shows a drawing of a man holding his
skin in his hand, as if it were his clothes. “Stripped of skin, we are
all alike”, she says.

We may also have noticed that the person sitting next to us uses cosmetics or has a tattoo. We like to decorate ourselves. “Humans are self-decorating apes”, jokes
Jablonski. Cosmetics are used to highlight certain features,
particularly the ones thought to be sexually attractive. Tattoos appear for a variety of reasons, but usually to
signify somethink we think important, so much so that we want to make it permanent, on
the surface of our bodies.

It’s worth noting that none of this is a recent
phenomenon. We know from the
study of classical and pre-classical Egypt that the cosmetics industry
existed for many years there, particularly in the area of eye-shadow
and eye-liners. An ice man with tattoos was found in the
Tyrolean Alps, where he had been preserved for more
than five thousand years.

Concluding her talk, she appeals to us to think more often about
our skin, and about how we used to communicate with each other by touching. For generations we lived in groups like that were in constant
contact with one another--and that contact was physical rather than electronic.

So how come we do so little of it now? Jablonski blames the lawyers. “America is a touch-averse society,
mostly because of the layers of litigation that have come to prevent us
from touching in most public spaces and in the work place”, she says.
