What Are The 7 Realms of Biogeography?

If you're like me, the term "continents" has always left me wanting more, so let's try something different and see if we can define and divide the Earth's landmasses based solely on their native plants and animals.

Special thanks to Christopher Scotese for all his help with the paleogeographic component of the video!

Mad respect for that one marsupial making it half way across the world

Pinus Genus : *exists

Biggus Dickus : finally a worthy opponent

What must have been pretty interesting is that Antarctica during the warmer periods would still have had complete darkness for months at a time. It would be cool to know how the flora and fauna adapted to those circumstances

I was doing homework but this seems more important

I didn't know geography was so controversial

"The Australasian realm"
Zealandians: "Them's fighting words"

It would be interesting to see a similar video on biology of the oceans and their different realms.

The Seychelles islands also have a very unique biogeography since they separated from Madagascar and India 80 million years ago leading to it having very unique flora and fauna

Excellent. Judging by shape alone, I always wondered why India found itself ranked as a subcontinent while Arabia did not. Your computer modeling of the movements of the various plates over time, however, makes the distinction now clear. Great job.

I love that "Oh yeah, and Antarctica" is still a thing

The redefining guy is an absolute maniac stay away from him.

Thus should be a full length movie... with music. Or a whole Netflix documentary series.

When he said that some types of elephants started an aquatic life, my fantasy started to wonder in joy, trying to imagine such a marvelous extinct animal. Then he said they're dugongs...

His voice sounds weirdly happier than previous ones.

This is honestly the most interesting thing I've ever learnt about animal and plant evolution. I wish they taught us more about the dynamics of it in college and such, it would probably make it easier to learn and keep it interesting

Just think: One generation of species native to a thriving Antarctic ecosystem represented the last, and ultimately missed chance to migrate to South America or Australia to save the fate of their species from certain, frozen doom, and they didn't even know it.

When a video is well over twice the "mandatory" 10 minutes, you already know it was made for passion and not money. And it shows!

Fun fact in Indonesia, we were also taught Weber's Line, that has the line slightly to the east, making Indonesia's biogeography was split into 3 regions, Asian (Indomalayan), the Wallacea region, and the Australasian.

5:20 Would you look at India smashing up into the land mass and lifting up the Himalayas. Beautiful visualization.
