00:00This is, hands down, my favorite clever invention for Mother Nature.
00:03And it's right here in my backyard.
00:05It's a seed pod from a Japanese maple tree.
00:07Now on the tree, it grows flat like this.
00:09But as soon as it starts to prepare to fall from the tree, it dries up.
00:12Which makes these two wing things twist up and curl around.
00:15Looking like blades on a propeller.
00:17Because that's exactly what they are.
00:19Propellers.
00:20Nature invented the helicopter 40 million years before we did.
00:24But why?
00:24Well, if you're a tree, you don't exactly have legs.
00:26You just walk around planting seeds wherever you want.
00:28So the most common way to do it is to just drop them on the ground and hope.
00:31Because the further your seeds drop from you, the more it has a chance to survive.
00:34Because it won't have to compete with you for resources like sunlight and water.
00:37So the helicopter shape slows their fall and gives the wind more time to blow them further away.
00:42And that's how Mother Nature beat us to this invention.
00:44The trees with these propeller mutations were able to plant their seeds more successfully.
00:48Which means those randomly improved genes will keep getting passed on and keep getting improved upon.
00:53Eventually giving us tiny tree helicopters.
