Welcome to my channel! My name is Dr. Polaris and I'm quite the curious bear. Here you will find fun, educational videos on a variety of topics, including Zoology, Paleontology and History. If you are also interested in Speculative Evolution, you have come to the right place. You can find my own personal spec zoo project, detailing the history of an alternate universe where the K-PG mass extinction never took place at DrPolaris at Deviantart.
I think giant lemurs should be on television for documentaries and otherwise to help bring awareness to help the other lemurs that still survive but still struggle to cope with humans.
3:47 Hans Edge is actually a pretty important, and controversial, figure himself as he was responsible for re-establishing the Dano-Norwegian colony in Greenland and might have introduced smallpox to the island, which devestated the indigenous Inuit population.
Pikas are so cute. :-) I'm almost disappointed they don't occur in Europe, only in Asia and North America. Hares are an old favourite of mine. They're very underrated fauna.
The oldest known pachypleurosaurus and oldest known sauropterygian from my (European) country is some 244 million years old. Not quite as old as the initial diversification explosion of the early Triassic, but still within those first few million years of greatly expanding reptile biodiversity of the Triassic, including that of marine reptiles.
"Described as being 40 feet long and having the weight of a 7 foot tall elephant" I've watched this video many times and that part never fails to make me laugh
Animals & insects did not evolve God almighty created all the dinosaurs & extinct animals ever known ; Genesis 1:25 & God made the beast of the earth after his kind & cattle after their kind & every thing that creepeth upon the earth after his kind: & God saw that it was good. Scientists know that the first human was black and so scientists suggest that humans came from Africa just because Africa is where current black people live but Adam & Eve were created in Mesopotamia not Africa
A topic I have been itching to see someone cover, despite the animals being very well known in the modern day, any coverage of their fossil record has been very scant. The record itself is understandably very hard to pin down in a lot of places, but even the relatively recent species rarely got covered elsewhere. Well done!
damn, so the osprey's strategy has worked well for a long time. Not to mention a lot of birds seem to stem from that initial diversification after the KPG extinction or not long after, whereas mammals seems to have more species go in and out of their respective niches, with the current dominant herbivores/carnivores being more recent arrivals in those niches. Not sure how true this is in reality, but just something I thought I noticed.
I find it fascinating how the lack of fossils and a bias on size has messed up our understanding of the big group we currently know as Accipitridae. Genetics has revealed that "eagles" evolved in many lineages, and "vultures" evolved in several lineages. But genetics alone can't always pinpoint which change came first. A few clues in form of fossil bones rediscovered in some ornithology collection would be very helpful. As far as I understand it, genetics suggests that several of the splits within Accipitridae may go back a long time, e.g. the snake eagles or the bearded vulture group, and would justify introducing new families.
Andrewsarchus could have had a body design very much like a whale, all we have is part of the skull so scientists may have gotten it very wrong like they did with spinosaurus.
I dont really think intelligence has something to do with them being rare in tar pits. Both smilodon. and dire wolves are pack hunters and their groups would contain quite a few members. Making them more abundant in numbers.cave lions must have been a lot less in numbers. Thats why their represntation is very small. Take a modern day example, when lions hunt buffaloes hyenas call other hyenas that not necessarily the members of their own clan. Within a short period of time well over fouty to sixty hyenas will get there to drive away the lions from the fresh kill. Due to powerful preys of prehistory predators like even smilos and dirus will need a lot of buddies to take them down. And afterall these are cave lions. Not extroverted crowd pullers or mud/ tar bathers of prehistoric times.
I remember seeing a documentary some years ago about how in Scotland a motorist hit a large black cat. It wasn't a panther or cougar, but it was much bigger than a domestic cat. Various experts were asked to have a look but nobody could identify the species so they did a DNA test. They discovered it was a male hybrid of a Scottish wildcat and a domestic cat but much bigger than either. It wasn't that tall at the shoulder but about 4ft long.
Birds are so interesting and diverse you can go from Hawks to an interesting group like eagles, please do Hawks next, that’d be a great video tuah watch
