Bird Evolution: The Mystery of Feathered Dinosaurs | SLICE SCIENCE | FULL DOCUMENTARY

[@georgecarberry9222]

Just study a chicken. The rooster specifically. It's very easy to visualize a small raptor standing before you. If a rooster was as large as one of the medium sized carnivorous dinosaurs, there would be no doubt it descended from dinosaurs. In fact, roosters represent really ferocious raptors. They attack with their claws forward then, their beak goes in for the kill. Roosters can be exceptionally viscious & relentless. They can inflict serious injuries very quickly. Just imagine if they had teeth instead of a beak & a large sickle claw on each 3 toed foot, along with a long tail. Chickens are omnivorous & exactly like truly terrifying little pack hunting raptors!!!

[@BudgetFilmmaking]

A lot of the relationships become more obvious when you compare two things. I often wonder if non avian dinosaurs di the head bob thing when they walked, or if they had a bassy chirp or cluck. Take a close look at German cockroaches and praying mantises some time. You'll realize mantids are just roaches sitting up on their fat asses.

@@helenewalsh1750 Don’t be ignorant and naive. We are NOT destroying the Earth. Life on Earth will do just fine. If 5 major mass extinctions couldn’t “destroy the Earth,” then neither will human activity. If a rock the size of Mt. Everest slamming into the Yucatan Peninsula at 35,000 miles per hour 66 million years ago didn’t “destroy the Earth,” then neither will we. The Earth is not in a state of changeless ideal perfection. It is constantly changing. In the last million years alone there have been thousands of Ice Ages. 99% of all species that have ever existed are extinct. Which means that 99% of all species extant today will someday be extinct. Don’t worry about the Earth. The Earth will do just fine. There has been life on Earth for 3.8 billion years. There will probably be life on Earth for ANOTHER 3 billion or so years. So what is the danger? Is it that we’ll “destroy the Earth”? Nope. The danger is that too-rapid environmental change may render our modern globally interlinked civilization unsustainable. If civilization collapses, there will be a population catastrophe beyond anything anyone can imagine. But life on Earth will go on without too much change. And if mass extinctions can teach us anything, it’s that every end is a new beginning. Without the Permian extinction, the human species wouldn’t exist.

"Feathers on legs did not become a useful adaptation or survive into modern birds." Uh, pretty much all modern birds of prey (raptors, although not sn exact term) have feathered legs, even feet (owls!). Some more than others. Bald Eagles have capri "pants" of long feathers, but scaled lower legs and feet, as do falcons. Golden Eagles have fully, thickly feathered legs all the way to its scaled toes. They provide warmth, muffle sound for better hunting (esp silent owls), cushion and warm eggs and chicks when incubated and brooded, for protection, and probably other uses. I think there might be other species that have leg feathers of some kind, just can't think of any atm. I know more about raptors. I can't believe the writers made this huge mistake! Although it seems like a pretty good doc. But does make you wonder what else the writers left out, or why it wasn't reviewed by a scientist or at least someone familiar with birds.

[@oftin_wong]

Almost all birds legs are covered in scales It's thighs are feathered, the upper part of the leg ...but not the leg or feet ...that's the difference Sure there's going to be some outliers ...I think you'll find that scales predominately cover the eggs and feet of the majority of bird species Almost without exception birds have scaled legs it's a byproduct of evolving from reptiles

[@MyGratian]

Chickens and Tyrannosaurus rex (T. rex) are linked through evolutionary history. Birds, including chickens, are modern descendants of theropod dinosaurs, a group that includes T. rex. This connection means that, despite their significant differences in size and form, chickens share a common ancestor with T. rex. Key features like feathers, certain bone structures, and even some behavioral traits can be traced back to this ancient lineage.

[@OmateYayami]

I think in the hind sight it's not very farfetched to imagine birds are descendants of dinosaurs. If they were as abundant as mammals and generally feathered and a great calamity happened nowadays and only avian mammals like bats would eventually survive. Reptile people could think in a couple dozen million of years you have to be skinned and furred to be able to fly, due to light and elastic skin, and it would to fragile to live on surface where everything has a dense thick scale skin. Finding s semiavian mammal like sugarglide would be eye opening and great mammals having fur would be crazy. Something like that seems imaginable, so reverse - feathered Dinos seem quite plausible.

[@trollking99]

I'm of the dissenting opinion that dinosaurs did not evolve into modern birds. Birds and dinosaurs have many anatomical differences: different hip sockets, different tails, and different respiratory systems. To date, no fossil has been found of a creature with both unique bird and unique dinosaur features which would show the evolutionary progression. Any fossil that has been found with proto-feathers is actually decayed collagen, not feathers. Archaeopteryx is not a dinosaur, it's a pre-historic bird, even though it's still touted as the link between dinosaurs and birds. Birds and dinosaurs actually co-existed, so it's possible that they may share a common ancestor, but dinosaurs did not directly evolve into birds. These are not just my opinions, many researchers have come to these conclusions over the last few decades.

[@bonniemob65]

○The anatomical differences you listed are not differences at all - since they're not different between non-avian dinosaurs and birds at all: •One of the main synapomorphies of Dinosauria (a required characteristics an animal must have to be classed as a dinosaur) is a perforated acetabulum (or in English, an open hip socket). All dinosaurs have a perforated acetabulum, including birds, meaning birds meet the main requirement to be classed as a dinosaur (they also have the other synapomorphies, such as having an elongated deltapectoral crest, having a synsacrum, etc.). •The change in tail length can be seen very clearly in the intermediate/transitional fossils leading from early theropods to early birds - for example, dromaeosaurids (the family of dinosaurs that _Velociraptor_ and _Microraptor_ belong to) had anywhere from 25 to 35 tail vertebrae. Early birds such as _Archaeopteryx_ had about 23 caudal vertebrae, which is still more than modern birds. Then, as primitive birds developed from _Archaeopteryx,_ they began to have fewer tail vertebrae (e.g. _Zhongornis,_ with 13 tail vertebrae), and some even evolved an early pygostyle (such as _Confusciusornis)._ By the time you get to modern birds, they no longer have more than 9 free tail vertebrae, those being the vertebrae that don't make up the pygostyle. •Non-avian saurischians have the same respiratory system as birds - dinosaurs such as _Thecodontosaurus, Plateosaurus, Apatosaurus, Coelophysis, Majungasaurus, Aerosteon,_ and _Velociraptor_ (among many others that would make this list too long) have all been found with traits typical of having an "avian" through-flow respiratory system, mainly the pneumatisation of the vertebrae, ribs, wishbone (in theropods) and even some of the hip bones (e.g the ilium). There was also one diplodocid sauropod specimen, nicknamed Dolly, that was discovered with abnormal growths on its bones that were structurally consistent with bird flu (not suggesting that modern bird flu was alive 150 million years ago, but definitely a similar respiratory disease that affected non-avian dinosaurs in the same way that modern bird flu affects birds). ----- ○This documentary covers dozens of the transitional species that you claim don't exist, including _Archaeopteryx_ (which you address later in your comment) which doesn't meet the traditional Linnaean definition of a bird or even the modern definition of modern birds (crown Aves/Neornithes) - it has teeth, no beak, a retractable second toe claw, fully developed hands and separate clawed fingers, a long bony tail without a pygostyle. It can only really be called a bird since many palaeontologists say that the wider clade Avialae is the boundary of what is and isn't a bird, but it's still more visually similar to non-avian dinosaurs such as the dromaeosaurids, troodontids and anchiornithids than it is to modern birds, despite having the synapomorphies that make it an avialan bird. ----- ○The protofeathers are absolutely not decayed collagen fibers. They have a distinct branching pattern unlike collagen, and, as stated in this documentary, even have melanosomes that show what colour they would've been in life - collagen doesn't have melanosomes. ----- ○Those researchers probably include Alan Feduccia, who tried reclassifiying all non-avian maniraptorans as birds as well and John Ruben, who tried claiming that birds evolved from _Longisquama,_ a primitive neodiapsid with weird scales running down its back, which he interpreted as pennaceous feathers (why would pennaceous feathers evolve in a non-flying quadrupedal reptilian, which shares nothing in common with birds other than both being neodiapsids?). ----- Hopefully I've wasted my time and your username _(trollking99)_ is literal, meaning that this whole comment was just a joke that went over my head.

Bats evolved their own way of flying around 60 million years ago, with a flight skin between their fingers. Flying squirrels are rodents and can't fly, they glide with a skinflap. Platypus developed a beak which it why it resembles a bird. But it stems from ancient egg laying mammals just like the Echidnas.

@@moonshoes11 poking holes in evolution lol. Yeah seriously I have been looking into evolution for years now. It's a right mess more imagination then actual science. What science the can claim is usually full of flawed assumptions and arrogance.

[@moonshoes11]

@@vikingskuld Oh, you’ve been “looking into evolution” for years? And *still* don’t understand it? How do you counter Fossils, DNA, Biogeography, Anatomy, Analogous structures? And let me guess, you’re convinced consciousness doesn’t require a physical brain, based on your “looking into” science? Flawed assumptions and arrogance? How do you explain away novel, testable predictions? Flawed assumptions and arrogance is more like believing there is a master of the universe who wants a personal relationship with you. In other words, you have no formal education, but think you understand it better than those in the field of study who do.

Every example,we have of consciousness results from a physical brain. Physical brains came about after physics, chemistry, and biology. Do you hold a position where consciousness could occur without a physical brain? And what evidence could you offer to make such a conclusion?

[@al20o33]

why are all the recent feathered dinos only found in China and nowhere else??

[@asthemoonturns]

Luck I guess. It´s rare for soft tissues like feathers to fossilize, and then survive for millions of years. But when conditions for such fossils are right, you tend to get many of them from the same place and time. That's why the Archaeopteryx fossils (from Germany) were found in the same fossil beds as many species of small Pterosaurs (which due to their thin bones didn't fossilize very easy either).

[@jaysons6101]

Dakotaraptor, Utahraptor, and many more were found in the US.

[@blastulae]

Archaeopteryx is from Germany.

[@bonniemob65]

Most come from China, but there are a few that don't. There's: _•Shuvuuia_ from Mongolia _•Kulindadromeus_ from Uzbekistan _•Archaeopteryx_ and _Ostromia_ from Germany _•Ornithomimus edmontonicus_ from Canada •And _"Ubirajara"_ from Brazil. Hope this helps.

Birds remember, somewhere in their DNA, that they were titans once. With teeth and claws, where the mammal ancestors fled and hid before them. And they desire a return to such a time again.

Domestication

[@bonniemob65]

•Until 1988, the marbled crayfish _(Procambarus virginalis)_ didn't exist. Then a slough crayfish _(Procambarus fallax)_ was born with enough mutations that it could reproduce asexually - this also made it a separate species from its ancestors. •The Long-term _E.coli_ Evolution Experiment observed _E.coli_ evolve the ability to aerobically grow on citrate multiple times - _E.coli_ is defined by its inability to grow aerobically on citrate, so these mutant populations were technically no longer _E.coli._ •The ability to drink milk comes from a mutation that allows humans to be able to break down lactase as an adult - ancient humans lacked this ability, and even today most humans are lactose intolerant since they either didn't descend from ancestors who had this mutation, or they were simply born without the mutation. •As Rayman11 said, domestication - artificial selection is one of the mechanisms of evolution. It was even the first thing that Darwin discussed in On the Origin of Species, because he recognised that this was a mechanism that his readers would be able to understand, since humans have been making new domestic animal breeds for millenia. •The fossil record - many of the species in this video are great examples of the evolution of feathers (with the very primitive feathers of the ornithischian _Kulindadromeus,_ to the long display feathers of _Caudipteryx,_ to the flight feathers of _Microraptor, Anchiornis_ and _Archaeopteryx._ In addition, looking at the change in the skeletal features from _Sinosauropteryx,_ to _Caudipteryx, Microraptor, Anchiornis, Archaeopteryx_ and _Confusciusornis_ clearly show the progression from more basal dinosaurian characteristics to more derived avian charvateristics. This documentary also leaves out many in-between species for both the development of feathers and the evolution of birds from dinosaurs, such as _Dilophosaurus, Sciurumimus, Ornithomimus, Beipaiosaurus, Shuvuuia, Yi,_ etc.

Birds and other dinosaurs always are or were reptiles, like us. You cannot evolve out of your clades.

[@jaysons6101]

Thats factually wrong.

[@blastulae]

Nope. All dinosaurs were to a greater or lesser extent warm-blooded. One of the more warm blooded lineages evolved into birds, but the vast majority of them didn’t. All archosaurs have four-chambered hearts. That includes crocs and pterosaurs. Crocs evolved a hole in their hearts to downrate them for aquatic life. The other reptile group, lepidosaurs, ie lizards, snakes and tuataras, are cold-blooded, with three chambered hearts.
