The myth of the Missing Link--the idea that there must be a specimen that partly resembles an ape but also partly resembles a modern human--is persistent. But the reality is that there is no missing link in our lineage, because that’s not how evolution works.

Complexly has a new show! Check out Journey to the Microcosmos, which takes you on a dive into the tiny, unseen world that surrounds us:    / @journeytomicro

  • "Exchanging genetic material" Is that what the kids are calling it these days?
  • @Sup3rlum
    3:26 Java man was at an evolutionary disadvantage because he couldn't C#
  • "It's called the braided stream" she says, wearing a thematically appropriate hairstyle
  • Finally, approproate information to destroy the "where is the missing link" argument
  • @phoule76
    if someone steals your sausage, it's a case of a missing link
  • It's kinda funny how we had to stop using the tree model because it didn't account for combining/hybridizing branches, but real-life trees will absolutely fuze branches together on a whim.
  • The problem is education often lags behind scientific progress.
  • 22nd century: people realize that evolution isnt linear, nor is it a braided stream, but actually a 3d matrix
  • Well this video made more sense as it continued 😂 school got this so wrong. We definitely learned the progress of man missing link, and i graduated in 2014.
  • The evolution of evolutionary thinking is.... Revolutionary? Great episode!
  • I remember the Piltdown man , I had no idea it wasn't real though. This braided chain theory is pretty amazing stuff
  • @JR-gp2zk
    Reminds me of dogs, wolves and coyotes. They are all different yet they are similar enough to interbred. Homo sapiens are basically a coywolf dog hybrid.
  • @dg_96_7
    This makes so much sense. I used to be extremely skeptical about the missing link theory & the search for a fossil resembling both ape & man. The braided stream makes much more sense.
  • Recently new subscriber here. These PBS Eons episodes, especially those on human evolution, are becoming invaluable to an anthropology major who was last hitting the books on human evolution two decades ago and who wants to catch up on the most recent story. The Braided Stream model is fascinating. Thanks for all these concise synopses on these topics, not to mention the included references! Keep them coming!
  • And some people still ask the stupid question, "If we evolved from apes, why are apes still around?"
  • Can you guys please make a video on the discovery of the hobbit species (Flores man). Would love to know more about it, thanks!
  • @EChacon
    Hope you do one on Titanoboa and the animals from Cerrejón. 🐍🐊🐢
  • I actually had the privilege of handling the Taung Child once when I was younger. I’ll never forget that
  • It's 1912 and I am viewing this with astonishment on some sort of portable motion picture playing device that projects light and is impossibly thin.
