This video encapsulates everything that is positive in YouTube. I am well versed in the KT boundary event but have never seen it analyzed in such detail. Great video! Hope you folks with kiddos watch this with them and potentially inspire some new scientists, archaeologist, or any other discipline that might apply.

OMFG, the idiotic comments here are seriously scary. People actually believing this is all fake? How absolutely bizarre. It looks like only a small portion of humanity are able to use the brains that evolved. Thank you for an excellent presentation, biointeractive.

Outstanding recap of the search for the Asteroid that killed the dinosaurs and allowed the rise of humans. I would totally recommend this for middle school to adult and even younger if they are enthusiasts.

I still remember the day like it was yesterday when my 8 th grade teacher said with confidence that the dinosaurs died because there brains where too small.

If aliens are watching us, they are probably trying to figure out where they went wrong in educating us, and aren't sure if they want to accept the responsibility!
