…or the metre

Why is a meter a meter? The meter is the world’s ultimate measure, but how did it become “the” meter? What is this measurement based on? The story of this revolution in measurement traces its roots to the French Revolution. Scientists decided that an equal and united people should have equal and united measures. So they sent a pair of young astronomers out to measure the world, and invent the meter. Little did they know they’d find nothing but war, deception, and strife along the way. As a result of this ill-fated mission, the meter carries an error that still persists today. Still think the metric system is so perfect?

There will eventually be a day where prosthetics are no longer just for the disabled.

However, it’s not just our outside appearance that will change – our genes will also evolve on microscopic levels to aid our survival. For example, an Oxford-led study discovered a group of HIV-infected children in South Africa living healthy lives. It turns out, they have a built-in defense against HIV that prevents the virus from advancing to AIDS.

And with gene-editing tools like CRISPR, we may eventually control our genes and DNA to the point where we make ourselves immune to disease and even reverse the effects of aging.

Another way to jump-start the human evolution on a different path is to move some of us to Mars. Mars receives 66% less sunlight than Earth. Which could mean humans on Mars will evolve larger pupils that can absorb more light in order to see. And since Mars’ gravitational pull is only 38% of Earth’s, people born on Mars might actually be taller than anyone on Earth. In space, the fluid that separates our vertebrae expands, which led American aerospace engineer, Robert Zubrin to suggest that Mars’ low gravity could allow the human spine to elongate enough to add a few extra inches to our height.

However, not even a move to Mars could spark the biggest change in human evolution that we may have coming in the next 1,000 years: immortality. The path to immortality will likely require humans to download their consciousness into a machine. Right now, scientists in Italy and China are performing head transplants on animals to determine if you can transfer consciousness from one body to another. They claim their next big step is to transplant human heads.

Whatever happens in the next 1,000 years — whether we merge with machines or become them — one thing is certain: The human race is always changing — and the faster we change and branch out from Earth, the better chance we have of outrunning extinction.
