Just took a vertebrate zoology course this year, and I was told that the explanation at 3:03 was a misconception, and that actually all jaw-bearing species had ancestors with bony skeletons, but chondrichthyans underwent a secondary loss of bony skeletons (kind of like what happened to legs for snakes), likely to provide buoyancy to compensate for lack of a swim bladder (it seems to me a better name for Osteoichthyes would be Physichthyes, as the gas bladder seems to be their actual main derived characteristic). As for whether or not a beaver is a fish, I've decided the best answer would be that a beaver is as much of a fish as I am, and leave it at that.

I remember hearing a funny story in a biology class once: Before we had the ability to analyze genes, we classified animals based on shape, like mentioned in the video. Well originally, all raptor birds were considered to be closely related and were put in a group together called "Falconiformes" (Falcon-shaped). Well eventually when we analyzed the genomes of the birds of prey, it turned out the we were right. Most raptor birds are in fact closely related to each other, with one notable exception: Falcons. Because of this, falcons were not originally in the "falcon-shaped" group. Classification is fun.

@jaschabull2365 Год назад

At least Wikipedia seems to think everything but falcons got kicked out of Falconiformes, and most of the other raptors got put in Accipitrimorphae instead.

@Drakowyn Год назад

It's kinda the same with the Saurischia (lizard hipped) and Ornithischia (bird hipped) groups in dinosaurs. Saurischia have a hip structure that superficially resembles a lizard's while Ornithischia's resembles that of a bird. Yet birds are actually part of Saurischia and only later developed a structure similar to Ornithischia's.

@migitri Год назад

@@jaschabull2365 you (and Wikipedia) are correct. Per the South American Classification Committee, only Falconidae (falcons and caracaras) remained in Falconiformes based on Hackett et al.'s findings in 2008. Everything else (hawks, eagles, etc.) got moved to Accipitriformes.

It kinda blew my mind when we first went over cladistics in college. The prof used birds as an example though. Reptilia is paraphyletic unless you lump Aves in there too, so by cladistic standards, birds are reptiles. (Also, crocodilians are more closely related to birds than to other traditional reptiles).

@zackakai5173 Год назад

Couple of useful definitions for anyone interested: - A monophyletic taxon (otherwise known as a clade) is any group that includes ALL its descendants and NO others. In order to be a valid clade, it must be monophyletic. - A paraphyletic taxon (not a valid clade) is any group that includes some of its descendants, but arbitrarily excludes some specific subset (like excluding tetrapods from fish). - A polyphyletic taxon (also not a valid clade) is any two or more groups that are said to be the same thing, but don't have a common ancestor that was also that thing (surprisingly common in the old Linnean taxonomic system, because convergent evolution is a thing and that system was based on morphology rather than phylogeny).

Wasp phylogeny is all over the place. It's polyphyletic with loads of paraphyletic groups in it. The definition of a wasp is basically any hymenopteran insect that is not specifically called something other than a wasp. At least hymenoptera's a clade.

@DallenRex Год назад

I've always really like the phylogenetic and cladistic categorization because it feels a lot more explanatory and connecting than just semi-arbitrary categories. It's more about how things came to be, which is more of a story and easier to remember for me. It does definitely lead to some awkward language needed to identify some specific groups, though.

@spindash64 Год назад

Same. It’s just the logical order to match things up in. In addition, it’s usually a better measure of “under-the-hood” similarities, which are more important biologically much of the time than surface level things. For example, we consider it more important to call Dolphins Tetrapods than to group them with everything that swims, because the act of swimming is not as critical in “how do you not die?” As the function of getting oxygen to metabolize, and Dolphins, like all tetropods, primarily due this thru Lungs, not Gills This is just a more consistent approach to the problem

@DallenRex Год назад

Yeah, and it lets you make inferences about other animals in a clade, because they're genuinely related and not just apparently similar.

@MenaceLendil Год назад

Those semi-arbitrary cathegories skin can be usefull in science when non discussing evolution. Sometimes you don't actually care whether organisms are closely related it's the outward traits that matter. In the microbial world taxonomy is a mess and still in the process of constant changes plus horizontal gene transfer complicates the issue. So it's often more usefull to reffer to bacterial strains by the traits they exhibitic rather then genetic relatedness.

On the other hand we have fish and chips, fishing and many other words using fish as an thing not as an category. It is a concrete word like bird, snake, bacteria not an abstract one like mammal, primate or amphibian.

@rebelappliance771 Год назад

The fact that all vertebrate tetrapods are derived from fish begs the question if some of the traits that make humans what we are (I.e, our creativity and perseverance) first originated in fish, especially if more complex thought started with them.

Calling something an animal a fish is like calling a plant a tree. Trees are not all closely related to each other and have evolved numerous times. Palm trees are closer to grasses than to pine trees. Tree is a meaningless term, taxonomically. But it's still a useful one for humans.

The problem with classifying according to descent is that our knowledge is incomplete and will likely always be so. Plus we have to reclassify each time new evidence forces us to change our minds.

Fish usually lay eggs in water and generally spend most or all their life in aquatic environments.” I got 3 of 3 marks.

@Weirdisjustabrownandyellowword 7 месяцев назад

Here's my definition: Any chordate in the class agnatha, a group of vertebrates that includes all descendents of the common ancestor of the majority of pelagic vertebrates, except for the descendents of the Devonian fish tiktaalik, the common ancestor of tetrapodomorphs, which diverged into several separate classes within the phylum chordata. All fish live in water, and can breathe using gills. Some species of fish can breathe air, but most cannot. Fish have fins for swimming and their skin is covered in scales, which are protective, overlapping keratin structures. Most fish have a swim bladder, which provides bouyancy in the water. Most fish are pelagic, having retained the ability to swim from their common ancestor. Fish reproduce by laying eggs in the water. They can inhabit both marine and freshwater environments, with some species inhabiting both.

My father put an end to the argument. "Shark, fish, what's the difference when it's bigger than the boat!"

A possible solution to this that I came up with: you could exclude anything closely related to land vertebrates (lungfish, lobefinned fish, etc) from fish and give them their own clade, protopoda maybe. Not sure if that would work.

In Louisiana, alligator counts. The idea is that you have to abstain from meat rich people grow to eat; stuff that a poor person would grub up to survive is going to be okay.

@BonaparteBardithion Год назад

My understanding was that they reinterpreted fish to be whatever protein source was readily available to trappers and settlers, at least as far as beavers go and I assume the same applies to capybara and gators. Another comment mentioned sailors eating penguin. The exceptions did seem to focus mostly on animals that lived at least part time in the water to justify it.

My favorite example of Cladistics gets weird, is the contagious dog cancer that is descended from dogs. Like the Henrietta Lacks cells, but with a vengeance. Also a great example of evolution producing an organism of a different "kind", since I don't think the most in denial creationist would call a contagious cancer causing single celled organism a dog.

In evolution u don’t stop being something.. grasping this absolutely makes this discussion very simple an easy to understand… good example “birds ARE dinosaurs” not “birds descended from dinosaurs” as that later leads to so many issues from many groups of ppl who use that wording for dishonest narratives … y’all know exactly who I’m talking bout… and the issue there as mentioned is how ppl use language and do so outside of that given conversation to basically be dishonest to try to undermine the whole theory of evolution.. I’m objectively a fish .. even had gills as a early fetus.. im just not a fish in the day to day general for the sake of convenience casual talk… so if u asked me if I was a fish I’d ask u “depends on what and how ur asking” but objectively I’m a fish … again u don’t stop being what ur descendent from… so it’s fairly simple to me…

One could define fish as a sort of 'reverse clade' of everything not a tetrapod; however, that would include bacteria, so one may wish to make two cuts. Fish = animals - tetrapods.

@dailyStoic641 Год назад

Finally! someone who’s asking the real questions

@kafuuchino3236 Год назад

I think the "all vertebrates except tetrapods" definition is fine, tbh! It's paraphyletic, sure, but it's still a useful category when talking about, say, the physiology or ecology of fish and how they differ from land vertebrates. It's not a clade, but cladistics is one way to look at the natural world, not the only way!

No to be a pedantic scientist myself, but the tree at 1:49 is dead wrong. It shows animals and fungi (which are opisthokonts, along with several unicellular organisms) as forming a clade with plants, which is absolutely not the case. Land plants are in a completely different part of the eukaryote tree, while Entamoeba and Slime Molds (both amoebozoans) should form a clade with opistokhonts. This actually supports the overall message of the video, because it means that multicellularity has emerged several times independently and that "complex" organisms such as plants, fungi and animals are all more closely related to a bunch of unicellular species than they are to each other! Thanks for a great video :)
