Afrotheria: A Brief History
Вставка
- Опубліковано 1 лют 2020
- Afrotheria (literally, "African Beasts") includes seven groups of mammals with little superficial resemblance to one another: elephants, sea cows (dugongs and manatees), hyraxes, aardvarks, sengis, golden moles, and tenrecs. Despite their apparent dissimilarities, they are now widely recognised as having descended from a single common ancestor that existed somewhere in what is now Africa and had already diverged from the common ancestor of most other placental mammals.

It breaks my heart. Sirenians are the sweetest, kindest, and most affectionate peaceful beings on our planet.
I feel so sorry for Steller cows! Would be fantastic to have them around.
Criminally underrated channel. Also love the mammal talks. We never get these types of focus of the mammalian taxa. Hope the rest of the other four are coming.
Now I wonder what the major predators in Africa were before mammals from Eurasia crossed into Africa.
I love how elephants and elephant shrews come to be as closely related as they are.
These are not animals, these are escapees from The Muppet Show
Fantastic video Dr Polaris . Congratulations on 500 subs well deserved. Keep up the good work .
YOU THINK MOLE PEOPLE IS JUST A JOKE BUT THERE ARE COMMUNITIES OF HIGHLY INTELLEGENT MOLES THAT KNOW STAY UNDER THE RADAR.
Relationships between elephants, manatees and hyraxees was already well known in late 1980s. I know this, because I made a presentation to school of hyraxes and a classmate had one of elephants in the same day, and we were both happily suprised. And I remind manatees, because they were so different, in particular.
American manatee didnt fear people because Indigenous probaly saw the manatee as people espewsialy if they have the five finger that easy to indentify there was this belief some had that five finger animals where all related which is kinda cool Incorect but a neat organization attempt blending science ??? Naturalism and spirituality
A lot of them seem to have some pretty funky teeth and noses, is that ancestral or convergent?
“Oh look! Two videos uploaded at the same tim- wait a second why are they the same thin-.....oh one was taken down by copy right...”
Congrats on the 500 subs!
Fun Fact;
Why is hearing zoological and even botanical lectures delivered by a dry British accent so comforting?
I heard that Hyaenodontids might be members of Afrotheria as well.
This channel is criminally under sub'd.
Very good!, thank you.
This channel has been a welcome discovery. I have had the best Zoology classes of my life here. Congratulations and very grateful, Dr. Polaris!
Yes, you've reached 500 subscribers. Times 64. Besides: very professional video placing the animals in a geographical context.
