Without humans I could see the Sauropsids (birds, reptiles) becoming dominant again after a great extinction (asteroid) kills the mammals/ synapsids. But humans are too intelligent. They will deflect any asteroid & eventually learn to control the weather, so earth’s mammals will live in comparable paradise (no extinction).

If Im not mistaken, the platypus and echidna are the closest Permian-like creatures we have

True but even then, very very distantly related to the protomammals

@@posticusmaximus1739 If you take it up to the point monotremes diverged from other mammals, those 2 taxa are _equally related_ to stem mammals.

That's literally what they are

Mammals and synapsids aren't the same. They're close.

@vyhozshu "theyre not modern mammals. theyre proto-mammal (often retaining reptilian features from the split from reptiles) that include things that wouldnt become mammals, dead ends, similar how dinosaurs were proto-avian to modern birds. you don't say we call dinosaurs birds?" 1. modern mammals (and all extinct mammals) are synapsids 2. proto- or stem-mammals are synapsids 3. synapsids (which covers all stem-mammals and mammals) didn't evolve from or split from reptiles, that's obsolete knowledge 4. birds are dinosaurs, the terms are avian dinosaurs (birds) and non-avian dinosaurs (all other dinosaurs) ------------- I'm a zoologist, your understanding of these things is very muddled, I'm happy to help.

@@ryanstatt9910 Mammals _are_ synapsids.

Mammals are synapsids, but synapsids aren't necessarily mammals.

Milk evolved from modified sweat glands. Even modern day platypuses still sweat milk through pores on their belly rather than having nipples. The precise time when fur evolved is unknown due to a lack of fossil evidence of hair, but it's been shown through embryological studies that hair is highly modified scales. Hair probably evolved as a sensory organ first, like modern whiskers, several cynodont skulls have small holes at the front that look very much like the holes in modern mammal skulls that carry blood vessels and nerves that supply whiskers.

Considering synapsids like Estemmenosuchus were found to have glandular hippo-like skin, its possible that synapsids never had scales to begin with or scales were only present in non-therapsids (Varanopids had scales, but are not believed to be synapsids anymore)

Not really. Mammals have grown beyond synapsids. Otherwise you might as well just call mammals the 3rd coming of amniotes.

⁠@@mnomadvfxIt’s different because there are multiple amniotic lineages left, and they have always been successful because dinosaurs were amniotes too. However mammals are the only lineage of synapsids left. Also it’s always been the age of insects, we’re just living in their world!

The Age of Mammals could also be called the Second Age of Synapsids easy. They are dominant on land, sea, and they even try to rival birds on air @@mnomadvfx

@@mnomadvfx We are still synapsids nonetheless. But we are still living in the Age of Tetrapods, though.

The world is owned by Dino bird and insects. They outnumber all animals including small other animals. We just dominate because they won't grow large​@@bigjilm9559

What's the misnomer and why?

@@Dr.IanPlect thank you for asking. The word "cell" is misleading; we get the image of a building block or our body. But to the contrary, as we look closer, it appears to not only have its own controlling systems but things are actually mobile inside it, not controlled by our brain, and on smaller and smaller scales, it, the "single cell", could have infinite complexity. It's like saying "single human" being or "multi -human" being. Fine to use the word cell like that too, so long as we can do the same for human or planet....

@@thomasschwarz1973 No, that's not how cells are thought of, even to the general public, and doesn't constitute a misnomer. And you're yet another person misusing 'then'.

I sure don't see them surviving and building structures that aren't simple rocks

@@timohara7717 right so by "them" I assume that you mean bacteria. You know, i just learned that algae are a type of bacteria, cyanobacteria.... Of course you are right, only us humans have this imagination and ability to execute our plans so amazingly well.... But as we look deeper into that human life, it does appear to be based on bacteria....

invalid

@gunther4150 NO diapsids are extinct. The family tree that challenges us synapsids are the sauropsids (dinosaurs, birds, reptiles) .

Easy video to watch and understand, maybe look into your cognitive abilities. Shouldn't take long for you to see how retarded you are. Although it might, since you don't see your own special needs

He's Italian and I can understand it just fine. Yes, there is Chimerasuchus, ExtinctZoo and PaleoAnalysis provider a lot of coverage on the Permian/Triassic periods.

6k mammals, 10k birds

So they are at odds just like all those 350 million years ago

There still are more insects and fish i think.

Scientists estimate that insects make up to 90% of all species of animals on the planet and more than half of all living things. So insects never really left the ruling seat.

Why would you define "ruled by" as "most numerous"? By that logic we're all ruled by germs. This is such a weird bit of semantics that I don't think you've thought through.

Don't wish it might trigger deeply religious people 😂😂😂😂😂

And from essentially only cynodonts

Very relavant ending, but you're showing your intelligence. Or lack thereof
