Hello, Mythbusters!
Here's a quick roundup of the latest discoveries from all kinds of areas.
There's proof Vikings lived in America 1000 years ago! The scientists analyzed wooden objects found at an archaeological site in Newfoundland. They've determined that Vikings lived there in 1021. Can you imagine crossing the ocean back then?
Horses come from Russia. Analyzing DNA of hundreds of horses showed that the modern domesticated horse originated somewhere around the Pontic-Caspian steppe. This area was settled by a bunch of peoples, including Huns, Bulgars, Khazars, Hungarians, Cossacks and Russians.
Tuskless elephants are the latest to confirm the theory of evolution. Over the years, the ratio of tuskless female African elephants rose from 18 to 51 percent, which seems to show that the elephants have adapted to the emergence of ivory hunters. However, elephants need tusks to dig in the ground for water or strip trees from bark, which they eat.
The use of an atomic clock has confirmed that gravity indeed affects time. Einstein theorized that a clock will tick faster the further away it is from Earth or another large celestial body. Now, an amazingly precise clock confirmed that height difference affects the speed of the measured time.
