What's behind this antivax movement? Are vaccines safe? How do vaccines work? Why do some people claim there is a link between vaccines and autism?

SUBSCRIBE, it's FREE! http://bit.ly/iotbs_sub Every fall, in cities like New York, the smell of vomit fills the crisp air. The culprit? The pungent seeds of the ginkgo biloba tree. So why would a tree evolve such a disgusting and revolting way to disperse its genes and make baby trees? Why not be more like the delicious apple? Join me for an evolutionary ghost story. We'll find out why the ginkgo is so weird, visit with some prehistoric beasts, and learn how an avocado is a bit like a dodo bird Check out "Ghosts of Evolution" by Connie Barlow: http://amzn.to/1iLBpsb Why the avocado should have gone the way of the dodo: http://blogs.smithsonianmag.com/food/2013/10/why-the-avocado-should-have-gone-the-way-of-the-dodo/ More about evolutionary anachronisms: http://sydkab.wordpress.com/tag/evolutionary-anachronism/ The ginkgo is Earth's oldest tree: http://e360.yale.edu/feature/peter_crane_history_of_ginkgo_earths_oldest_tree/2646/ Janzen and Martin's 1982 paper "Neotropical Anachronisms: The Fruits the Gomphotheres Ate": http://bit.ly/1aO0qiY Joe Hanson - Host and writer Joe Nicolosi - Director Amanda Fox - Producer Katie Graham - Director of Photography Andrew Matthews - Editor and Motion Graphics Kate Eads - Production Manager Filmed at Onion Creek Productions in Austin, TX Thanks to Dan Silver for the footage of ginkgo trees in NYC Produced by PBS Digital Studios: http://www.youtube.com/user/pbsdigitalstudios ----------- Join us on Patreon! https://patreon.com/itsokaytobesmart Twitter http://www.twitter.com/DrJoeHanson http://www.twitter.com/okaytobesmart Instagram http://www.instagram.com/DrJoeHanson http://www.instagram.com/okaytobesmart Merch https://store.dftba.com/collections/its-okay-to-be-smart Facebook https://www.facebook.com/itsokaytobesmartpbs/ Learn more about your ad choices.

    Why Do You Love Your Family?

    Viewers like you help make PBS (Thank you 😃) . Support your local PBS Member Station here: https://to.pbs.org/PBSDSDonate Don't miss our next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub You can learn more about your personal DNA story by going to https://23andMe.com/okay ↓↓↓ More info and sources below ↓↓↓ 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. SOURCES: This video covers more than a half century of evolutionary biology theory and observation, but here's some reading if you'd like to learn more: Dawkins, Richard.
