00:00Bees can do math, and they understand zero, a concept humans didn't even invent until
00:06a few thousand years ago.
00:09In 2018, researchers in Australia trained honeybees to fly down a tunnel.
00:14At the end, there were two cards with different numbers of shapes.
00:18If they flew to the smaller number, they got sugar water.
00:21They learned to pick one, two, three, and four shapes correctly.
00:27Then came the real test.
00:29The researchers showed them a blank card, an empty set, nothing.
00:34The bees understood instantly that nothing is less than one.
00:38They flew to the blank card.
00:41This is huge, because zero isn't just nothing, it's a number, a concept that took human civilizations
00:47thousands of years to invent.
00:49We had math for centuries before we figured out zero.
00:52And a bee brain is the size of a sesame seed, with less than one million neurons.
00:59We have 86 billion.
01:01They can even learn to add and subtract if you train them with colors as plus and minus signs.
01:07So next time you see a bee, remember, it's not just making honey, it's doing math you
01:13didn't learn until elementary school.
