Discover how humans lost their fur as they evolved from primates, and why we still have hair on our bodies.Uploaded 03-06-21--We have lots in common with our closest primate relatives. But comparatively, humans seem a bit… underdressed. Instead of thick fur covering our bodies, many of us mainly have hair on top of our heads— and a few other places. So, how did we get so naked? And why do we have hair where we do? Nina G. Jablonski explores the evolution of human hair. Lesson by Nina G.

Explore the physics of flight, and discover how aerodynamic lift generates the force needed for planes to fly.--By 1917, Albert Einstein had explained the relationship between space and time. But, that year, he designed a flawed airplane wing. His attempt was based on an incomplete theory of how flight works. Indeed, insufficient and inaccurate explanations still circulate today. So, where did Einstein go wrong? And how exactly do planes fly? Raymond Adkins explains the concept of aerodynamic lift.Lesson by Raymond Adkins, directed by Michael Kalopaidis, Zedem Media.This video made possible in collaboration with Marriott HotelsLearn more about how TED-Ed partnerships work: https://bit.ly/TEDEdPartnersSupport Our Non-Profit Mission----------------------------------------------Support us on Patreon: http://bit.ly/TEDEdPatreonCheck out our merch: http://bit.ly/TEDEDShop----------------------------------------------Connect With Us----------------------------------------------Sign up for our newsletter: http://bit.ly/TEDEdNewsletterFollow us on Facebook: http://bit.ly/TEDEdFacebookFind us on Twitter: http://bit.ly/TEDEdTwitterPeep us on Instagram: http://bit.ly/TEDEdInstagram----------------------------------------------Keep Learning----------------------------------------------View full lesson: https://ed.ted.com/lessons/how-do-airplanes-stay-in-the-air-raymond-adkinsDig deeper with additional resources: https://ed.ted.com/lessons/how-do-airplanes-stay-in-the-air-raymond-adkins#digdeeperAnimator's website: https://zedemanimations.com----------------------------------------------Thank you so much to our patrons for your support!
