Half of All Languages Come from One Root Language. How it Spread Is Something of Debate

Compelling evidence makes the case for both the Steppe and Anatolian Hypotheses. 

 

The sheer variety of languages on Earth is dizzying in their array and divergence. What’s more intriguing, is that about half of them spoken today by some three billion people, come from a single root language, used thousands of years ago. Hindi, Bengali, Persian, English, German, Spanish, and Greek, all come from the same root, known as Proto-Indo-European (PIE). In total, 400 languages and dialects originate from PIE.


German linguist August Schleicher reconstructed its vocabulary back in 1868. He wondered what PIE sounded like. So he created a fable called “The Sheep and the Horses.” Over the years, as more information has been unearthed about the Bronze Age cultures who spoke this language, the fable has been updated. Of course, scholars argue over what PIE actually sounded like. Nothing is definitive. But we have an approximation.

Here’s the latest recording of spoken PIE performed by University of Kentucky linguist Andrew Byrd:

Why are so many objects in space shaped like discs?

It's one of the most consistent patterns in the unviverse. What causes it?

Videos
  • Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
  • Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
  • Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.

Trauma in childhood leads to empathy in adulthood

It's not just a case of "what doesn't kill you makes you stronger."

Mind & Brain

  • A new study suggests children who endure trauma grow up to be adults with more empathy than others.
  • The effect is not universal, however. Only one kind of empathy was greatly effected.
  • The study may lead to further investigations into how people cope with trauma and lead to new ways to help victims bounce back.

Do human beings have a magnetic sense? Biologists know other animals do. They think it helps creatures including bees, turtles and birds navigate through the world.
