What If Our Bodies Kept Evolving?

what will humans look like in 10,000 years what about in 1 million years will we look like this guy yeah probably not but we'll definitely look different than we do now what parts of our body would evolve how long would evolving our bodies take and who would win the survival of the fittest this is what if and here's what would happen if our bodies kept evolving it took roughly 6 million years for humans to become what we are today and modern humans have only been around for about twelve thousand of those years even in that short period of time humans have evolved slightly we've become about 10 centimeters taller and now we can eat dairy foods after childhood so if those things can happen in 12,000 years where might we be hundreds of thousands of years into the future first we should probably figure out exactly what evolution is evolution is all about changes in the genetic makeup that happened to a species over time species with more advantageous traits will tend to have more offspring so those genetic traits will tend to carry on to later generations for example giraffes with longer necks who can reach more food will be able to survive better than giraffes with short necks and they'll be able to have more babies who will likely have longer necks just like their parents and as time goes on the short necks giraffes will die out and the long neck giraffes are the only ones left that's why all our giraffes today have long necks so how does this apply to humans exactly well evolution in this sense is actually very hard to predict in the world we live in don't need to worry about survival of the fittest technology has effectively cancelled a lot of that you no longer need to worry about being the fastest or the strongest this isn't 100,000 years ago when you had to fight for your food things like houses to live in and clean running water make surviving it's so much easier you never think to yourself how am I going to survive today but that's something our ancestors had to worry about constantly it's not guaranteed that 1 million years from now humans will be stronger faster and bigger than ever before after all having children today is generally decided by culture and personal choice rather than the need for our species to survive our future will be decided by the traits of people who have children and how many children they have if people who are naturally overweight and have health problems are the only ones having kids over the next million years then that's how the human race will end up but we might not need to worry about any of these natural occurrences instead we could become completely fused with technology before any of this happens cybernetic arms brain chips and laser eyes could all become possibilities not only that but we also might be able to alter a baby's genes before they're born completely getting rid of evolutional together this would allow us to get rid of diseases and any other genetic traits that might harm us but if we didn't have this luxury and we had to evolve the old-fashioned way there's a few things that might happen we just need to look at how modern humans have evolved in the past twelve thousand years we know we've been getting taller most likely due to nutrition and that our brains have been getting smaller but don't worry we haven't been getting dumber our brains are actually becoming more efficient so in a million years we might be incredibly tall humans with tiny heads does that remind you of anything at the end of the day human evolution is incredibly difficult to predict that's because evolution is primarily based on our environment and who knows what might happen to the earth in the next million years we might need to evolve to survive fires as the planet will become so incredibly hot I so hope I'm not around for that or in the next million years we might live on other planets like Mars humans would evolve to look completely different there as they'd be living in entirely different conditions than here on earth wondering what living on the red planet would be like well that's a story for another what-if
