Humans in 100,000 years: What will we look like?

Modern-day humans may someday evolve to have larger eyes, more pigmented skin and a thicker eyelids, thanks to genetic engineering technology. Here's how they'll change.(Nickolay Lamm / MyVoucherCodes.co.uk) In 20,000 years, in a world where genetic engineering is commonplace and humans have established colonies in space, human knowledge of the universe will increase andas such, the size of the brain will increase, Dr. Alan Kwan theorizes. As a result, the human head will have to become larger to accommodatethe larger brain size.(Nickolay Lamm / MyVoucherCodes.co.uk) In 60,000 years, Dr. Alan Kwanstates that after millennia of traveling through space, zygotic genome engineering will be used to create humans with larger eyes, more pigmented skin and a thicker eyelids. This will be done in order to see better in the dimmer environment of space, to shield humans from the UV rays and alleviate the effects of low to no gravity like today’s astronauts on the International Space Station.(Nickolay Lamm / MyVoucherCodes.co.uk) 100,000 years from now, Dr. Alan Kwan believes that futurehumans will have much larger eyes and “eye-shine” due to the tapetum lucidum, a layer oftissue behind the retina of theeye. This would be done to help protect our eyes from cosmic rays.(Nickolay Lamm / MyVoucherCodes.co.uk
