00:00Kuya Chris, why do zebras have stripes?

00:04Why?

00:05Because they don't want to be spotted.

00:11You're laughing.

00:12You're laughing inside, Kuya Chris.

00:15Okay, fine. I'll laugh.

00:18But the next thing we'll watch, Kuya Chris,

00:20this is not a joke anymore.

00:21This is real.

00:22This is serious.

00:23About zebras.

00:24I like that.

00:25Let's watch this.

00:27Science can answer all kinds of questions about the world.

00:31But there are still a lot of mysteries.

00:33Like, how many galaxies are there in the universe?

00:37But let's go back to your question.

00:39Because I'm also wondering what the stripes are for.

00:42There's an evolutionary theory.

00:45And according to it, it's not just for form.

00:47It serves to help the zebras survive.

00:50For a long time, it was thought that stripes are to avoid predators.

00:55It's said that it's confusing for a zebra to choose an opponent from a troop.

00:59It's possible.

01:00But there are new theories.

01:03It's said that stripes are possible so that zebras don't get hot.

01:06Like an air conditioner.

01:08It's so cold.

01:10It's said that black stripes absorb more sunlight than white stripes.

01:15It's a reason for the wind to circulate in the skin of the zebra.

01:18It's against the heat.

01:19It's also said that stripes are a defense against the bite of predators that spread to the inhabitants of Africa.

01:26Because of the stripes, zebras look different from horses.

01:30No two stripes are the same.

01:32That's why it helps them to know each other.

01:36Like fingerprints.

01:38There are three kinds of zebra.

01:40The most common is the small plain zebra,

01:42the endangered Grevy's zebra,

01:45and the rugged mountain zebra.

01:49Like horses, zebras live together and always race to find food.

01:56They are not picky.

01:58Dry and hard grass is fine.

02:03Fresh grass is for other animals.

02:06It's like a lawnmower.

02:09In each troop, there is a smaller group of family.

02:13One male, his wife, and their children.

02:18From the age of 1 to 3 years old,

02:20the male stallions are ready to join the troop

02:23to take care of their children.

02:27Until they grow up and can build their own family.

02:33But it's amazing when they fight with each other.

02:36There are fights, fights,

02:38and sometimes they go home in disgrace.

02:42And if they are attacked by a lion,

02:45they will just surround it until it retreats.

02:49Not only are they pure form,

02:52zebras are also brave.

02:54I believe!
