@@nihilanthropus Technically either we are all fish, or fish is meaningless as a concept.

[@mothic5889]

The fact that cephalopods are related to clams and snails, which branched off so early in animal evolution, is exactly why their intelligence is so fascinating. Most animals we consider "truly intelligent" are vertebrates, with similar brains to our own. Octopus have evolved their intelligence completely independent of this and done a few things differently along the way, like spreading their brain neurons all out in their arms with only 1/3 of them actually in the "brain". I'm an evolutionary biology student, and I love examples like this because they reveal a lot of interesting things about the flexibility and constraints on the evolution of things like brains and intelligence.

[@Simon-np8bt]

As a biologist i really enjoyed watching this video because i find all of the questions quite easy to anwser and just watching someone with little biological education struggle to answer these by using basic logic was really informative because things are not as straight forward and intuitive as one might think. Evolution never ceases to amaze me. Great job btw. Looking forward to see your new channel!

[@roidrannoc1691]

As a biologist, while the video is interesting, I wouldn't recommand such a tree to learn phylogeny... It has such a 19th century vibe,. The fact that he said at the begining that sponges are related to jellyfish is quite the issue I have about this tree... I find the OneZoom tree of life (built as a fractal) way better (yes I know, you can't make a poster out of it)

[@dreadpirateroberts1358]

Not a biologist but I'm studying it atm, and it's really fun to see him answer. The struggle reminds me of myself when I was starting and it's just relaxing. Though I did notice a small issue on the chart somewhat early on. Didn't chrdata evolve from a sponge? The tail of the mobile stage of the sponge eventually didn't go away and became a primitive cartilagenous backbone that then that evolved further into individual bones creating true backbones?

[@Simon-np8bt]

@@dreadpirateroberts1358 I believe you confused tunicates with sponges because some benthic adult tunicates look similar to sponges at first glance. Sponges (or maybe ctenophores, there is still a dispute) are the very basal lineage, the sister group to all other animals, while tunicates are a sister group to vertebrates. I agree that this poster as any other phylogenetic poster gives way too much emphasis on vertebrate lineage and omit like 20 animal phyla alone, and almost all other non animal organisms. And for some anthropocentric reasons humans are always on the top center. But I get it, vertebrates are the most complex and most familiar organism around us.

[@dreadpirateroberts1358]

@@Simon-np8bt That is what I was thinking of. I looked it up to be sure. I learned it from I don't even remember anymore and the word they used was sponge. I'm definatly glad to learn the correct origin of the backbone tho. But yeah this emphasizes vertebrates way too much. Same with animals and eukaryotes.

Hymenoptera literally means membrane winged

[@Stettafire]

Some ant species, worth mentioning, don't reproduce the same way as most ants do so in some very rare cases a species might not have any winged members at all

An interesting thing regarding the "Did Dinosaurs coexist with grass?" question. Piperno and Sues (2005) described fossilized Dinosaur dung from India, which had phytoliths consistent with grasses, more specifically something similar to rice or bamboo. Furthermore, Wu, You & Li (2018) described grass microfossils that were found associated with Equijubus from China from the Albian. So grass for sure coexisted with dinosauria a lot more than previously recognized! Also I love these unscripted videos, they show your personality and knowledge well.

One thing I had to do for a fish biology course in college was memorize the entire line of scientific categorizations (kingdom, phylum, subphylum, all the way down to species) for a handful of species, one of those being lamprey which are indeed jawless. Surprised you’ve never heard of them; they’re infamous to me as the fish who attach themselves to a host and suck blood out to feed (although there are non carnivorous species too).

[@legoboy468]

Lampreys are tasty! They are good both fried on coals or smoked. The first inch or so of the fish is normally not eaten, it contains the liver and most other internal organs, and of course the hard teeth which it uses to latch on to bigger fish in order to feed on them. The inedible part is easy to see as it is a kind of a bump when the rest of the fish is sleek, and it comes off easily when cooked. Lamprey is served whole and as is, and eaten by hand like it was rope licorice, the kind you can get from festival candy stalls. 2022 hasn't been a good year to catch lamprey at my location, as water levels remained low so far and the lamprey can't get upstream in local rivers because of that. Oh and lampreys definitely don't have jaws. Their mouths are circular holes lined with teeth. It is quite interesting really, to know that teeth evolved before jaws.

classical old-evolutionary tree-of-life representations usually have the main-branches of the trees as thicker whereas divergent secondary lines not linked to main-groups happen to be represented minor-side lineages as the Agnatha (jawless fishes i.e. Petromyzontidae /lampreys and Myxin / hagfishes) turn out to be apart of the main branch of all other vertebrates with jaws henceforth the Gnathostomata main branch. They´re a kind of old-fashioned and more complex-interpretative way of seeing evolutionary trends towards complexity and not tending to be fixated into simplified uniformity as cladistics, because they add VALUES into evolutionary trends towards complexity into groups, and not so see all into a relativistic uniformity based on all just genetics as modern cladistics.

I respect your openness and ability to admit ignorance in front of a camera. I am surprised to find you, a talented naturalist, struggling a bit with the taxonomy in this way, but I guess it just shows we all have very specialized knowledge, and we don't know what it is that we don't know. Some of this stuff is intuitive to me, but you have taught me things through this channel that I didn't even have the first inclination toward understanding. Your video, "What is a nebula?" would be a great example: I thought I knew so much more about nebulae than I actually did before you released that one lol. I had a lot of misconceptions. Not to mention my lack of skill and experience in exactly this: acknowledging how little I actually know in the grand scheme of things. Just a fun fact, I'm pretty sure the next-closesnt extant relative to elephants and sirenians is the hyraxes. You'd never think so just from looking at them. Also, 30:39 Did you say "I guess it is the first arthropod, I guess other than water bears?" Do you care to elaborate on that? Because AFAIK, tardigrades are in their own phylum, not Arthropoda. Wikipedia says they are closely related, at least as far as phyla go, and some have proposed a clade called "Panarthropoda," which includes Arthropoda, Tardigrada, and Onychophora (velvet worms). So technically the first arthropod would be the first species to diverge from water bears, right? Or perhaps it's the other way around, the first Tardigrade was the first species to diverge from from the ancestor of arthropods. Or was your statement simply what you briefly inferred based on the branches of the poster? In either case, it appears to me that tardigrades and onychophorans both diverge before the label of Arthropoda on the poster. Maybe the distinction is bordering on semantic, but I have always suspected that in the highly technical realm of phylogeny, that kind of pedantry might be necessary and non-trivial lol Again, this isn't like a "gotcha" or a criticism so much as just a discussion; I'm not here to put you down for having the nerve to upload nearly an hour of you admitting/realizing what you don't know in real time and staying open to the process of learning, on camera, in front of thousands of people-in my opinion, that ability, and the desire to keep educating oneself, will always be more admirable than simply knowing a lot of things. I sincerely feel inspired by that. I want to be more honest with myself and others about how much I still have to learn, instead of playing things off like I have it all figured out (when I so clearly don't). 47:20 "I'm kinda surprised, they didn't really ask a lot about plants . . . plants take up a very small part of this tree of life, even though in reality they make up at least an equal aspect of the life on Earth, if not... honestly, definitely, more than all the animals." If we're talking about number of extant species, there are just SO many insects out there though. One estimate I found of the makeup of 7.2M total living plant and animal species (presumably excluding bacteria, archaea, fungi, etc.): total plants - 390,800 vertebrate animals - 80,500 invertebrate animals - 6,755,830 !!!!! Five million of which are insects. Another estimate I found (Mora et al. 2011) puts total animals at 7,770,000 species and plants at 298,000 species
