Anyone has thoughts on why they had mammals be down to a single species 100 million years in the future? They didn't seem to really give more explanation than "a lot today are endangered" (like... yeah? And?) and seemed to imply that the heat wouldn't be suitable for them. But:
- Mammals have lived through the Eocene Thermal Maximum.
- Mammals live in really hot places nowadays.
- There will still be cold places in 100 million years.
One thought I have is that they simply wanted surprising and interesting concepts and didn't care all that much on why mammals disappeared.
This is discussed in the episode about the great plateau, it's the penultimate one of disc 2 I think.
