00:00Happy Sunday, my iBelievers!
00:03This morning, we're going to travel around the world!
00:06Wow! I really want to do that, Chris!
00:08I really enjoy traveling.
00:10So, I'm ready to go to any part of the world.
00:13Do you know why?
00:14Why?
00:15Because I'm sure that wherever I go,
00:18I'll find my fellow countrymen there.
00:20But do you know that in the past,
00:22only one place in the world was inhabited by people?
00:26Now, there are people in every corner of the world.
00:30But 200,000 years ago,
00:32people only lived in one of the seven continents,
00:36Africa.
00:38Migration is the process of moving from one place
00:43to another part of the world.
00:44It's done by animals,
00:46from the smallest fish
00:48to the largest whales,
00:51especially humans.
00:54A good example is the most famous migratory bird in America,
00:58the duck.
01:00If you live in America,
01:01you probably won't see ducks all year long.
01:04Why is that?
01:06You guessed it right.
01:07Migration.
01:09They move places whenever it gets cold.
01:12When it's hot in the northern part of America,
01:16it's fresher there.
01:18But when it starts to get cold,
01:20they go to the south,
01:21where the climate is hotter.
01:23They do seasonal migration,
01:25and that's one way for animals to travel.
01:29Under the oceans and rivers,
01:31there are fish that migrate.
01:34Salmon swim for almost 6,000 miles in a year
01:38to return to the place where they were born
01:41for them to lay eggs.
01:42The longest distance that an animal traveled was in 2015.
01:47A gray whale set a world record
01:50for seasonal migration.
01:5222,527.5 kilometers in 172 days.
02:22The Olduvai Gorge is rich in rocks
02:25from lava, chert, and quartzite.
02:28These rocks are strong and sharp,
02:29so they made tools that can be used to mine them.
02:33Because of this,
02:34the ancient people were ready to travel the world.
02:39How did the ancient people know where they would live?
02:42It's simple.
02:43They walked by the sea.
02:46The natives are rich in natural resources.
02:49They have water and food.
02:51Because of this,
02:52they were able to discover the depth of the country.
