Wonders of Life — S01E04 — Size Matters

00:00:27 Our world is covered in giants.

00:02:59 The size of life on Earth spans from the tallest tree,

00:06:15 As the sharks start to circle, it's time to get in.

00:09:17 the largest animals that have ever lived have lived in the sea.

00:11:39 and so whilst it provides support,

00:14:42 I've come to track down one of Australia's most iconic animals...

00:17:11 Kangaroos move so efficiently

00:19:08 To understand why this is the case,

00:21:07 This is the left femur, the thigh bone

00:23:10 it has a cross-sectional area 40 times that of the wombat femur.

00:25:32 At a much greater size, their bones would be very heavy,

00:27:54 then it would appear that God has an inordinate fondness

00:31:02 As things get smaller, it is

00:33:34 when it hits the ground.

00:36:05 it becomes possible to live within the lives of other individuals,

00:38:54 seeking out the moth eggs.

00:41:19 bacteria are structurally much simpler and far, far smaller.

00:43:40 extend beyond dictating the relationship

00:46:08 multiplied by the six faces is 24.

00:48:25 If you plot the amount of energy an animal uses against its mass,

00:50:42 Now, there's another theory that says that it wasn't really

00:53:03 Named Christmas Island when it was spotted on Christmas Day in 1643,

00:55:34 So these crabs, over that lifespan, inhabit many different worlds.

00:58:07 and ultimately, how long you have to enjoy it.
