Back in the day, our ancestors had some seriously cool superpowers, but they gradually disappeared because, well, evolution's a thing. Take hibernation sleep, for example—not as flashy as flying, but imagine snoozing through winter and waking up when it's all warm again, no biggie. Scientists reckon our ancient relatives, like way before humans were a thing, might've been snoozing champs to survive. Some fossils suggest they lacked Vitamin D and fat reserves, hinting at a possible hibernation state. And hey, remember how our ancestors had super-strong teeth? Turns out, munching on tough stuff kept 'em healthy, but then we discovered sugar and, well, you know the rest. #brightside Animation is created by Bright Side. —————————————————————————————- Music from TheSoul Sound: https://thesoul-sound.com/ Check our Bright Side podcast on Spotify and leave a positive review! https://open.spotify.com/show/0hUkPxD34jRLrMrJux4VxV Subscribe to Bright Side: https://goo.gl/rQTJZz —————————————————————————————- Our Social Media: Facebook: https://www.facebook.com/brightside Instagram: https://www.instagram.com/brightside.official TikTok: https://www.tiktok.com/@brightside.official?lang=en Stock materials (photos, footages and other): https://www.depositphotos.com https://www.shutterstock.com https://www.eastnews.ru —————————————————————————————- For more videos and articles visit: http://www.brightside.me
