The ability to drink milk throughout our lifetime, known as lactose tolerance, evolved about 10 thousand years ago.
Over the last century and a half, the average height of a human being has increased by roughly 10 centimeters and within the last 6 and a half decades the global life span has shot up nearly 20 years largely thanks to science.
Breakthroughs in science have propelled our species forward.
In fact, National Geographic and GE's new series "Breakthrough" covers some cutting edge innovations that are happening, today, from biology and technology merging to solutions for our water crisis.
But, what will humanity look like in 1000 years?
It's already hard enough to remember a world without smartphones, but scientists predict that within the next few decades, computers will reach the computational speed of the human brain.
Not only will they be able to speak and interact, but listen and remember.
This also leads to a philosophy known as transhumanism.
In the future, nanobots or tiny robots will be subtly integrated into our bodies enhancing our own abilities!
No longer will we be limited by our own physiology, but truly become a mixture of biology and machine on the inside.
