Pigs in the Pacific: A Journey Through Time

Pigs have been moving around the Pacific islands for thousands of years. This isn't just a fun fact. It's a big deal. These pigs changed the islands forever. But how did they get there?

The Science Behind the Story

Scientists looked at pig DNA and teeth. They studied over 500 pigs. They also looked at teeth from pigs that lived long ago. This helped them see how pigs moved around.

A Mixed Background

The pigs in the Pacific have mixed backgrounds. This means different pigs were brought to the islands at different times. But they all have one thing in common. They are linked to pigs from China. These pigs came with people who spoke Austronesian languages. This happened around 4000 to 3000 years ago.

Waves of Migration

The study shows that pigs were brought to the Pacific in waves. Each wave brought new pigs. These pigs mixed with the ones already there. This created the pigs we see today.

Unique Teeth, Unique History

The teeth of these pigs are unique. They look different from other pigs. This is another clue about their history. It shows they came from a specific place and time.

More Than Just Pigs

This story is about more than just pigs. It's about people. It's about how they moved around the world. It's about how they changed the places they went. And it's about how scientists can piece together this history.
