We often think we've found it all, but in the new millenium we have found we share DNA with Neanderthal and discovered a man called Denisvovans that we also share DNA with. We find new discoveries in the bottom of the ocean and new caves on the earth. In fact, only a few years ago, the largest cave in the world was discovered!
Here's some newer caves discovered in recent years -
This newly discovered cave in British Columbia is believed to possibly be the largest on in Canada! The opening has a waterfall that tumbles over 1000 feet into a blinding mist.
"Hang Son Doong"
This cave was discovered in 1991 and is so far the largest cave in the world.
Found 20 years ago in Spain, this cave is a giant geode! The giant translucent crystals are below an abandoned silver mine.
