I'm watching this video because I'm making a DnD monster and I want to better understand biology as inspiration for a fantastical creature and how to define it in words that anyone can understand. I don't thing the problem is necessarily anti-science people, we need more science *invested* people. For a lot of people, watching a complicated video like this is complicated and confusing and boring.

This is great, thanks so much Dave. This really helped me to understand better why Protostomia is divided into Spiralia and Ecdysozoa. I'm so excited to learn about all the more obscure phyla such as priapulida, velvet worms, loricifera, etc.

The word 'basal' refers to the place where it branches, the sponges were the first animals to branch off, before all other animals branched off.

@rheiagreenland4714

Of course, you could still say that humans branched off from the common ancestor of us and sponges just as long ago as they did from us. Basality only makes sense in relation to a specific group. Sponges are more basal to all the other animals than any of them are to each other. You could still group all the other animals into their sister clade and say that they were more basal to all the sponges than any of them are to each other. There's nothing special about either non-sponge animals or sponges, it's an arbitrary decision based on what groups are most specious, familiar, and contain humans.

Just a quick question - would Protista really be polyphyletic if it's defined as "any eukaryote that's not an animal, plant or fungus"? Presumably that'd include the common ancestor of all eukaryotes, so all protists would share a single common protist ancestor rather than evolving from separate origins, so it'd be the eukaryote clade with the three other kingdoms removed from it. That sounds paraphyletic to me rather than polyphyletic!

@pmathewizard

2 жыл бұрын

A common ancestor with some but not all of its descendants is referred to as paraphyletic, whereas a common ancestor with all of its descendants (a clade) plus at least one outgroup taxa outside of the initial clade is referred to as polyphyletic. If Protista is deemed paraphyletic, then all Eukarya major taxa's common ancestor must also be Protista or be considered as such. With the current molecular and morphological data, it is accurate to say the classification Protista is a polyphyletic grouping that consists of clades which are the outgroup of the clade of (Animals, Plants, Fungi)

@shadowmax889

The thing is, Protist as a group is weird, it includes protozoans and many groups of algae. It is polyphyletic because not only it doesn't include animals plants and fungi, but because they have unique life forms that don't relate with the other kingdoms or each other. I think it should be divided in many other kingdoms and subkingdoms that includes plants, fungi and animals

If we went back in time 500 million years, would the tree of life have fewer layers to it? In other words, would there be populations that we now consider to be orders or families, but back then would be considered a species because they hadn't diverged yet? If everything I just asked is correct, does that mean that we'll need to come up with a new layer at some point? It seems like we can't change the definition of species, and we can't really change the definition of domain, so where would that layer go?

Yea what you asked is obvious to assume since the biodiversity would be too scarce 500 million years back to categorise organisms into the current taxonomical system. For future evolution & branching of organisms - yea we might need new sub-categories to categorise em depending upon what they’ll evolve into. We already have sub-families, super-orders and sub-species.

I believe you’re being a bit melodramatic. There are many species of invertebrates ( spiders, insects, gastropods,crustaceans, molluscs, etc.) that have yet to be named mainly because no one has taken the time to do the research . Unless you have a strong interest in it, taxonomy can be quite tedious. If you go through the literature as I said you will find a ton of unnamed critters in many ta

I may have missed this video, or it may be outside your expertise, but it would be a really cool somewhat related video if you can explain how things like catalysts, co-evolution/evolution not being a completely independent function, and self-organization make evolution and the type of diversity we see not an one in a gazzillion chance like people who don’t understand science pretend (I am looking at you Kent Hovind and other like-minded people) but it is actually a fairly likely thing to have occurred

This is probably hard to believe, but after all your flat earth debunk vids, there is still a group of stubborn people that neglect the sphere model. I just came across a pretty hardcore flat earth group on facebook: The Flat Earth Model. What they don 't realise is that in their attempt to prove that the earth is flat since "I shouldn't see that far... They actually use the known earth's radius. How did they come up with that number.

Ah, sloth botany. Oh you thought I mean sloth zoology, no, sloths have blue-green algae and moths and other creatures. They are a small ecosystem themselves. The problem with some of the way people divide animals taxonomically is that it is too evolution specific. If we had a time machine maybe we could find out all our evolution ideas are wrong and would have to scrap this whole thing. Birds and mammals both have backbones while ants don't. If we found out that birds actually came from ants tens of millions ago that doesn't seem like we should move birds away from the chordate phylum into the arthropod; or even make a new one.

We can say with highest confidence birds did not evolve from ants based on genetics, transitional fossils, anatomy, etc. You're not wrong to say we may have some classifications incorrect, which is why we are continually studying these things to correct ourselves. In any case, the ONLY valid way to classify animals in a cladogram is with monophyletic clades, so taxonomy has to be evolution-based.

Not sure if you're joking, but flowers never would have turned into zebras because the two are in completely different kingdoms (flowering plants in Plantae, zebras in Animalia). Thus, they do not share a most recent common ancestor. If you're asking why we don't see evolution today, I can assure you we do. Speciation has been observed in the wild and induced in the laboratory many times. Most of the time, this involves relatively small changes which can compound into major changes over many generations. See Aron Ra's series "Systematic Classification of Life" for a more in-depth look at the paleontology behind the system. Also, if you're mentioning Jesus because you think evolution is anti-religious, rest assured that it's entirely possible to be a Christian and accept the reality of evolution.
