Why Is Blue So Rare In Nature?
There
are blue animals, but the species are small in number compared to the
other colors among living things, such as red, orange, yellow, and
brown. Sure, when we look up to the sky, we see blue. When we look at
the Earth from space, we see a blue marble. But the few animal species
that look blue don't use pigments -they use physics. And those physics
are complicated. It turns out that animals are better at engineering
than they are at chemistry.
Okay,
there's one exception not the pigment thing, which we learn about in
the video. Our friends at It's Okay To Be Smart explain why it's so hard
for nature to create the color blue.
