Most of us have felt it before, that strange sensation that you've been somewhere or seen something before, as if you already remembered what's happening. Are you psychic? Nope, that's just déjà vu. Why does déjà vu happen? Well, scientists aren't completely sure, but they've got a few good theories about it.

14 min - Why Do We Cook?

Your brain is hungry. Here's how to feed it.
SUBSCRIBE, it's FREE! http://bit.ly/iotbs_sub
Ever wonder why we cook our food? We do it because it tastes good, of course, and because our customs and traditions are built around it. But we also cook our food for some basic biological reasons, because of evolution. Some scientists think that figuring out how to cook actually MADE us human!
If conversation gets a little dry around your holiday table, now you'll have some awesome science to share with everyone!

Why do we love people we're related to? Compared to strangers, why do we feel such a deep sense of connection with our family members? Sure, they're nice to us, we take care of each other, and we often live with them, but there has to be a deeper biological reason. That reason, unsurprisingly is evolution. In this video, I explain why taking care of our family, or even dying for them, makes sense in the eyes of evolution.

Support our show: https://www.patreon.com/itsokaytobesmart↓ More info and sources below ↓Why do Africa and South America fit together? Anyone who’s ever looked at a map can see that Earth’s continents are kind of like a jigsaw puzzle. The idea that continents are constantly moving and weren’t always in their current spots is a pretty obvious idea, right? You might be surprised to learn that geologists only accepted that idea recently in the past few decades, and it figuring out how plate tectonics and continental drift work required some pretty strange evidence.-----------LEARN MORE:Some background on Alfred Wegener: http://www.ucmp.berkeley.edu/geology/techist.htmlLystrosaurus (ancient mammal relative): https://en.wikipedia.org/wiki/LystrosaurusGlossopteris (ancient fern): https://en.wikipedia.org/wiki/GlossopterisThe splitting of Africa: http://theconversation.com/splitting-africa-what-happens-when-a-continent-breaks-apart-6248-----------FOLLOW US:Merch: https://store.dftba.com/collections/its-okay-to-be-smartFacebook: http://www.facebook.com/itsokaytobesmartTwitter: @okaytobesmart @DrJoeHansonTumblr: http://www.itsokaytobesmart.comInstagram: @DrJoeHansonSnapchat: YoDrJoe-----------It’s Okay To Be Smart is hosted by Joe Hanson, Ph.D.Director: Joe NicolosiWriter: Shaena MontanariProducer/editor/animator: Andrew OrsakProducer: Stephanie Noone and Amanda FoxProduced by PBS Digital StudiosMusic via APMStock images from Shutterstock http://www.shutterstock.com
