Evolution has bought many changes in man; both in terms of physiological and psychological characteristics. Our primate ancestors had a skull size that was three times smaller than what we have today, which is a clear indication of how the physical characteristics change over the years.
Now, thanks to wearable technology like Google Glass, humans may look very different from what they are today, 100,000 years after.
Some 100,000 years later, the human eye would be large, saucer-shaped, the forehead huge, and the face would be flat; this, according to Nickolay Lamm, artist and researcher from MyVoucherCodes.co.uk.
Based on his discussions with Dr. Alan Kwan, a PhD in computational genomics from Washington University, Lamm has created a series of images which predict how the humans may look 100,000 years later.
"The fate of the human face will be increasingly determined by human tastes," Dr Kwan explains, adding that the human brain will continue to grow larger as time passes.
Kwan also believes that the eyes will grow to be much larger, owing to the possibility that humans may start living on different planets, in environments much darker, being away from the sun.
The eyelids are speculated to be thicker, and will have a more enhanced superciliary arch to balance the effect of gravity.
Also, the eyes would have several other noticeable differences, all of them aimed at coping up with the changes in the environment. To protect the eyes from the cosmic rays, the human body may develop a sideways blink, and have an enhanced low-light vision.
To add to that, there will be larger nostrils to help man breathe easier, thicker, denser hair to contain heat loss, and pigmented skin to reduce damage caused by the harmful UV rays outside the earth's protective ozone layer.
Medical and technological advancements may further add to that, lending parents the freedom to choose the genetic make-up of their kids, decide their eye color, body structure and more.
"Communications lenses (commlens) in contacts and miniature bone-conduction devices implanted above the ear will work in tandem," Dr Kwan predicted. "Bone-conduction devices, with embedded nanochips, will communicate with some external device for communications and entertainment."
