Birds Are Reptiles?

You know that reptiles are stinkin' rad pets. This is a fact! But do you know what a reptile is? Most people do not. Clint shows off some rad pet reptiles, and explains what makes this group special, and what doesn't. You might be surprised just how much you don't know about our cold blooded, scaly friends. Are they even cold blooded?

I never, in a million years, would have thought that there was be so many die-hard defenders of Linnaean taxonomy out there when I made this video. But I was wrong. I haven't been cussed out so much since I told you that iguanas generally make bad pets :) So, just so you know, humans like to organize things into categories. In the mid 1700s, Carl Linnaeus proposed one system for categorizing living things based on observable similarities. It was a useful system, but it had its limitations. Namely, organisms were grouped based on known attributes. If you knew that an organism went in a specific category, that didn't teach you anything about that organism that you didn't already know about it when you put it in that category in the first place. In other words, it was useful for organizing information, but totally uninformative. We have learned a lot since the mid 1700s. One thing we have learned is that living organisms are related to one another because they share ancestry with one another. Phylogentic analysis allows us to understand these family relationships better. Organism that share a common ancestor tend to share many attributes that they collectively inherited from their shared ancestors. This means that if we know where an organism fits into the tree of life, then we suddenly know an amazing amount about it even if we previously knew nothing. It is a vastly more useful way of classifying organisms. But given that many of the Linnean names have been used for centuries now, we are trying to fix a lot of the categories to be relevant given what we now know about shared ancestry. The only good kind of a group includes an ancestor and all of its descendants. All modern reptiles share a common ancestor, but they also share that ancestor with birds. If we are going to use the term "reptiles", then we have two options: we can either include birds, or we can accept that it is a garbage group. I prefer the former :) Hopefully this helps.

It's amazing to me how many people staunchly defend old science (or "science," as it were). The entire purpose of science is discovery. Discovery requires us to constantly reevaluate and replace. Holding to a particular teaching - regardless of new evidence to the contrary - is called religion. It reminds me of some of the people who absolutely love all things Monty Python. They will shred you alive for misquoting a line from one of his movies...even though Monty Python was the king of ad-lib. And don't bother trying to explain the irony to them. They don't do well with irony (which is, in itself, ironic). Anyway, thanks for the video. As always, it was very informative. Keep up the good work!

[@goku-san]

Birds are dinosaurs. So yes, they would be reptiles. I'm not sure why people had to be rude about it. Sheesh. Makes me wonder what they would say if they were told every vertebrate is a fish. Because cladistically, tetrapods (amphibians, reptiles, mammals, and birds) are emerged within lobe-finned fishes. So therefore, they can be called fish.

[@T2266]

I majored in analytic philosophy, so to me it's more of a "when you got an unwanted conclusion, go back to re-evaluate your premise" To me "bird being reptiles" is that unwanted conclusion, I had better time believing dinosaurs are not reptiles actually. Or rather, I was already on the side that doesn't consider dinosaurs reptiles.

@@Pistolita221 Use phylogeny rather than only taxonomy ranking, it better reflects natural evolutionary histories of the groups involve. Also last I checked, taxonomic ranking of Reptilia and Birds both just refer to them as "Clades" and not strict "Ordo" or "Familia". "Clades" is just like "neutral term" for a grouping and Clades do contain each other. Such as Sauropsida ("Reptiles") containing Dinosauria (which includes Aves aka Birds). This is why it is more helpful to think of their phylogenic relationship rather than getting stuck on arbitrary rankings.

[@Pistolita221]

@@khango6138 I believe their taxonomic rank is "class", which I believe is linnaean. Bird and reptile are linnaean terms. Aves are reptiliomorphs, and so are mammals.

Birds and mammals are pretty similar in some ways!

From waht I understand, dinosaurs are not even reptiles, since they are different enough, let along birds.

[@fireflocs]

T2266 There's a classification system that basically says that anything descended from a certain group counts as that group. Birds descended from reptiles, therefore, they are reptiles.

I read somewhere that human skin has no way to detect if it is wet or not, beyond sensations like movement and temperature. So one of the reasons why people described reptiles as 'slime' is because of a temperature difference that led to the feeling of wetness.

[@TheBuggyGal]

That's a very interesting observation! I have a ball python and while I know and can feel there is zero "slime," sometimes when he glides across my hands if I close my eyes I can trick myself into thinking there's slickness in the action from that temperature difference and also the extreme smoothness and softness of his scales. His scales also "glisten" (more like shine) in the light just from being healthy and hydrated, especially after a shed. That can give a visual illusion.

@Amber Rae Dawn Tollenaar I emphatically second this sentiment. The obsession with rare morphs in the reptile hobby is, in my opinion, sort of obnoxious. I understand there is a "collector" type interest in keeping reptiles, and I suppose that's not unilaterally a bad thing. However, the morph collecting and seeking (and breeding) of rarer and rarer morphs borders on obsession with rare stamps or coins. There's nothing wrong with collecting stamps or coins, but reptiles are living things and deserve to be respected as such instead of simply bearers of cool coloration. Additionally, appreciation of everything *but* the wild type of a critter takes people further away from appreciating the most common type of that animal which occurs in nature. I love that Clint brings in a biologist's perspective first, and only secondarily notes about the reptile hobby.

I was always taught in school that birds were a separate group! You learn something new everyday!

[@raymondwhatley9954]

The Linnaean system classed them that way and depending how old you are that might have even been the thought at the time. Our understanding of the family tree of life has improved a ton in the last few decades and we now know that birds are definitely reptiles. In school the Linnaean system is taught more because it's simpler. The true complexity of the tree of life is astounding. For example, you were probably taught that there are 5 kingdoms: Plants, Animals, Fungi, Bacteria, and Protists. In reality there's a level of organization above that called "Domain" which includes Bacteria, Archaea, and Eukaryotes (the first two groups include everything you were taught was "bacteria"). Eukaryotes then have a level of organization that doesn't have a real Linnaean name, but is sometimes called "supergroups" which includes some 20 odd kingdoms organized into like 6 supergroups with names like "excavata" and "opisthokanta" which is our supergroup. If we look at opisthokanta as an example we finally hit the level of Kingdom and find that it includes Nucleariids, Fungi, Animals, and Choanoflagellates. Plants, if you're curious, are in a completely different supergroup called Archaeplastida. But again, in school this gets squashed into only five "Kingdoms" to make it easier to teach to children. In fact, when I learned this in college I only learned about the upper parts of the tree because I'm a bio major and our teacher literally told us that the biology class for non-science majors taught the "five kingdoms" version instead.

Amphibians are tetrapods that lay anamniotic eggs, or in simple terms: they rely on a moist environment for reproduction. They generally have very permeable skin that dries out easily. The 3 major groups of amphibians are frogs, salamanders, and caecilians.

Now that I think about it, birds have a much more similar body plan to each other than to any other reptile, like other kinds of reptile. I mean, all birds have feathers, two legs, a beak, and wings (even if they wings cannot be used for flight) Similar to how all snakes have scales, no legs, and flexible jaws. It makes more sense for birds to be a smaller part of a bigger group than their own bigger group, the variability is comparable to creatures like turtles and snakes.

Egg-layiing is the primitive (basal) state for all amniotes including mammals. Placental development is just a highly specialized, form of internal, shell-less egg gestation in which the amnion (egg-yolk) has been replaced by maternal nutrition via the umbilical cord.

Birds are Archosaurs (ruling reptiles) a clade that includes crocodilians, pterosaurs, and dinosaurs (which birds are dinosaurs therefore they are also archosaurs). What people usually think of when they hear the word "reptile" are likely the members of the clade lepidosaurs, more specifically the order squamata which includes lizards, and snakes.

Excellent presentation.

Actually the closest living relative to the T-Rex is the chicken. They are genetically closer than any reptile and even crocodiles.

[@Real_MisterSir]

I think one of the main issues is that when the term "reptilia" was first coined, it was smack down in the middle of the Linnaean taxonomy way of categorizing animals with similar features - and most notably, birds were originally excluded from this list because of that - despite the common ancestor being grouped into reptilia as a whole due to the similarities of their known apparent features discovered from fossils. However, as the Linnaean way of categorizing animals didn't actually base itself on specific genetic distinctions, the term "reptile" was used as a broad slate for pretty much anything within the Sauropsida clade, regardless of the actual genetic differences and evolutionary paths. All animals belonging to Sauropsida were therefore treated as one based on Linnaean idea of what modern reptiles (lizards, crocks, etc) represented -so the more accurate way to look at the term "reptilia" is with a basis in what features are typical for a modern classified reptile -instead of looking at the farthest traceable ancestor to those animals. Therefore it is, from a scientific and taxonomical point of view less proper to view everything within Sauropsida as a reptile, since the defining traits of what is a reptile are inherently associated with what was understood when the term was first coined and expanded upon. Modern science and archeological studies have shown that Dinosaurs specifically (and thus birds by extend) have evolved in an entirely different path and in most regards do not live up to the original term "reptilia". Originally dinosaurs weren't excluded because our understanding of dinosaurs back then was far more limited than what it is today, even up until recently no more than 50 years ago our understanding was significantly lesser, and misrepresentation was more prevalent than accurate representation still. For this reason I see no modern reason to classify all animals belonging to Sauropsida as reptiles, as the specific distinctions that evolved the most consistent modern reptilian traits branched off entirely separate from dinosaurs and birds. At the very least it is a topic of scientific and taxonomical discussion that I do not believe has really been given just research, and is still open for modern nuance rather than relying on taxonomy founded in 1700s Linnaean ideas as the basis. By that extend we may as well say every animal is a single celled organism since all living things started there. Dinosaurs are already a large enough entity with clearly defined genetic traits that they can stand on their own similar to mammals and reptiles and fish. Reptiles, with our modern understanding, is simply too broad to be considered a scientific term unless we bring it back to the roots of what originally gave it its name: aka modern day reptiles and their direct close relatives and ancestral non-divergent path.. At least that would be my take. But until the scientific world unanimously come to such an agreement, I can of course not impose my analysis as anything more than that -an analysis.

[@Why79-dx4rf]

If we take dinosaurs out of reptiles, should crocodilians stop being considered reptiles, they are far closer to dinosaurs( including birds) then to all other reptiles. If you say yes, then should we take turtles/tortoises out of reptiles as they are closer to archosaurs like birds and crocodilians then they are to snakes or lizards. If you say yes to that as well, your basically just redefining reptile to mean lepidosaur, which I would argue is more contradictory to the average persons definition of reptile then just including birds.
