The Invisible LINE That No Animal, Bird or Fish Can Cross

The Invisible LINE That No Animal, Bird or Fish Can Cross

It was 1859, a 36-year-old man from Wales with his limited education suddenly became a key figure in biology. He discovered something you cannot see, you cannot hear, or even touch but it’s extremely important for studying biology and biodiversity in the world.

This is merely an imaginary line passing between two Indonesian islands. If you stand on Bali's coast and look east at Lombok, you'll see a narrow 32 km stretch of water that looks nothing special.

But if you look closely, on the western side of the line, the wildlife is typical of Asia, including species like rhinos, elephants, and tigers. The moment you cross the line to the eastern islands, you find a different mix of animals, such as marsupials, Komodo dragons, and cockatoos.

This is known as a biogeographic boundary called the Wallace Line, which marks the meeting point of two regions rich in biodiversity. And this invisible barrier runs through the Malay Archipelago, the largest group of islands in the world.

How did this invisible line come to be? Why does it affect where species live? How did that man figure out its location? Let's find out the answers to these questions in this video.

Wells? Indonasia? what? Typecal? Aisa? 3 million million? 1 million million? You should double check it i guess

Please make sure to add accurate English subtitles to this episode. Thanks.

I find this very interesting and informative.

I would think, most legends of history, have the ability to lie, cheat, and steal to gain fame.

Said: three million years ago
Written: Three million million years ago

Said: one million years ago
Written: One million million years ago

I think that this matter would be checked in the future

You're saying Wallace was the first to identify and describe and scientifically name 125, 000 plant species? That seems like a very unfeasible and unlikely amount even for a professional career spanning a few decades even with help help from a team. Anybody else? Or just me?

[PoeCompany]

This song is in every new YouTube video now lol

[adam]

Not bad but this channel has a lot of work to do

[nicole_elisabeth_smit]

How are you spelling indonesia??? Honestly, please hire a proofreader or dubbelcheck yourself. It's hard to take the channel seriously now.

[MayTheSchwartzBeWithYou]

Nice video. I was skeptical when I saw the view count, but I’m glad I clicked on it. Poor Wallace; I’ll never look at Darwin the same way again.
