Mad respect for that one marsupial making it half way across the world
-
I was doing homework but this seems more important
-
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

"The Australasian realm" Zealandians: "Them's fighting words"
-
Pinus Genus : *exists Biggus Dickus : finally a worthy opponent
-
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.
-
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.
-
I didn't know geography was so controversial
-
I love that "Oh yeah, and Antarctica" is still a thing
-
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 noticed Antarctica had a massive inner sea that was constantly changing but never completely drying, I wonder the isolated biodiversity could be under all that ice that evolved in completely different ways during its “golden age”.
-
It would be interesting to see a similar video on biology of the oceans and their different realms.
-
His voice sounds weirdly happier than previous ones.

You showed hyenas as canines but they’re actually feliforms. Canids evolved in North America, and didn’t come over to Eurasia and Africa until the bearing land bridge made it possible. Horses and camels also similarly draw their origins in North America in the Eocene
-
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.
-
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
-
i love the way that down in Tasmania we still get raspberries and olives that are native, and related to the European raspberries and olives. As well as a whole stack of plants left over from Pangea and Gondwana
-
I feel like New Zealand deserves to be its own biogeographic region considering it’s very unique flora and fauna, and geographic isolation.
