So many great points. It's like, "spiders can't be that distantly related to insects"... And then "they move with hydraulics instead of muscles" That's a crazy crazy difference...
0:20 Small correction: while it used to be believed that arachnids have a fused head and thorax like some other arthropods, the consensus is now that their ancestors never had a separate head and thorax to begin with. Because of this, the words cephalothorax and abdomen have recently been replaced by prosoma and opisthosoma as the preferred words for arachnid body segments.
It may also explain why they never evolved flight : they never needed it for dispersal ... Why fly when you can already cross oceans with no adaptations ?

In case everyone should know, arthropods (phylum Arthropoda) are currently split into two major groups, which are the subphyla Myriochelata (Myriochelates) and Pancrustacea (Pancrustaceans) with the former being split into the superclasses Myriapoda (Myriapods) and Chelicerata (Chelicerates) and the latter being split into the superclasses Crustacea (Crustaceans) and Hexapods (Hexapods).
But Myriapods are descendants of Euthycarcinoids, which I thought were linked to Crustaceans. Am I missing something? Or is the arthropod family tree still ambiguous?
@@havinfun7265, myriapods are more closely related to chelicerates than to pancrustaceans, therefore the two subphyla of arthropods are Myriochelata and Pancrustacea.

Heck yeah can't wait to watch, love spiders. We get big - but harmless - spiders here in South Africa called rain spiders and they are awesome to handle.
Years ago there was someone on Flikr taking macros of jumping spiders and photoshopping speakers in place of their eyes, making some race of rave monsters from space. It was brilliant.
@samsonsoturian6013 xenophobia, the fear of the different, is a significant problem in most societies and cultures. The instinctive aspect is less powerful than the learned aspect, but many people are either too ignorant, or too invested in their identity politics, or too keen to blame their problems on outside groups to avoid accountability to work to overcome xenophobia in themselves or their kids.
eh not exactly. Imagine being an early hominid. Imagine being bitten by some of those bigger spiders. The venom might not kill you (but might make you wish it would) but those bites almost always also cause severe infections. Infections that without antibiotics result in death. Being afraid of spiders was a survival trait.
I get flak for letting spiders make webs in my house...but those little guys eat all the bugs that i don't like (i've watched them do it!), so why destroy their homes? :P
I will let a spider chill in a corner of the room, but the if I ever see one on the floor/lower wall they're immediately gone. They can do their own thing so long as it's decently away from me. I am enforcing my own evolutionary pressure on them
After I raised up to 325k trading with her I bought a new House and a car here in the states 🇺🇸🇺🇸 also paid for my daughter's surgery (Joey). Glory to God.shalom.
they eat the stuff that really annoys me. Like flies and mosquitos. So I tolerate them and leave them alone. Never hurting them if avoidable by any means. They do their job and it benefits me.
I'm not fond of spiders, but one morning a fly woke me up, I stood to chase it away, and it got trapped in the web of a spider behind the radiator, and got eaten. Thanks spider friend
They’re cute, and it’s not their fault they look creepy and give me the shivers when I think about them 🥺. I will never kill one and I won’t allow others to.
for real dude, i love spiders! ive been trying to teach people not to be scared of them, and i even got my younger brother to hold one recently, so theres some progress!
Almost 300 years later, in this same area, people again turned against their neighbours and as a result millions of people died with no dignity. As a species, we can be very cruel to each other when we act on beliefs that are fed by fear. This was a beautiful presentation. Thank you.
There's the idea that the unique properties of spiders, such as their eyes and means of walking, conform to a pre-existing notion of creepiness, but maybe also they helped to create that notion of creepiness in our psychologies. (Like maybe the causality goes in both directions.)
Seeing such beautifully preserved arachnid fossils is so incredible, because of their exoskeleton it looks like they just looked at Medusa and got turned to stone
It's refreshing to watch a spider video made by someone who also seems to be arachnophobic 😭. I feel like spider lovers do not understand that phobia is not blind hatred and I'm kind of tired of that narrative in every arachnid video.
@@amogusenjoyeryeah Spiders arent even pests. They dont destroy the house, eats cables/clothes, eats human food and so on. If anything spiders in your hold significantly decreases pests in your household
Spiders are fine. I just helped a tiny baby one, it was on my indoor plants where there aren't any bugs, so i got it to crawl onto my finger and carried it outside and held a branch still on a flower bush I have and let it scitter onto it so it can hopefully find more critters, tho, it was SO TINY I can't imagine what it would possibly eat lol and jumping spiders, oh man! I love those little guys! And one day I found a solpugid, or vinigaroon, in my hallway, and I did the same for it as i did the tiny baby spider, I carried it outside and let it scitter off. They keep unwanted pest numbers down and don't want to eat me, I'm far too big
Strange, Ive held scorpions. I had a natural fear despite never seeing or being around scorpions but I managed to overcome it. I did not know spiders were related. It’s strange how spiders and heights and snakes are some of the most common phobias people have.
spiders actually have 'real' blood, as they breathe with lungs. Might be the reason how they can get so big whereas insects are quite limited by their circulatory system. Though, there is an idea that the insect size might be limited not by just gas exchange but also by their ability to shed heat (both are transferred by diffusion in them), whereas large spiders tend to be very metabolically quiescent, or have large surface to mass area.
@@viktorm3840 I would imagine that spiders don't use oxygen-carrying molecules like hemoglobin or hemocyanin which is what I would define as real "blood". Instead, that the free molecular oxygen dissolves into the hemolymph "naked".
@@jacksonhamilton6302 incorrect, as spider blood DOES contain haemocyanin, as does the blood of many underwater arthropods where the tracheae are impossible, and from whom they most certainly have inherited it. I would correct myself tho, as it seems that smaller spiders do have tracheae in addition to their lungs, as it seems that in the very small organisms, tracheae win over the low-efficiency, open circulatory system that arthropods such lobsters and spiders have.
Interesting. I remember in The Hobbit Bilbo insults the spiders attacking the dwarves by yelling "Attercop". I guess this is supposed to make them feel primitive or something
I love spiders. I let them live on my ceiling (or anywhere else really but they like the ceiling). If I lived in a country with venemous spiders it might be a bit different though.
just yesterday scientific american has posted a video about a german scientist studying sleeping spiders named "Do Spiders Dream Like Humans Do? This Researcher Wants to Find Out." must see IMHO.

I love spiders as a kid had a African tarantula.

A unique fact about spiders is -- due to ballooning juveniles -- they are the among the most common animals in the atmosphere as aeroplankton.
The horror knows no bounds
@@williamchamberlain2263 not really horror, they fly high and only fall on tree or building

I've been waiting for this video to drop from this channel for years, I love the evolutionary biology of spiders
I always try to be nice to spiders. They creep me out but they're just doing their thing. Especially jumping spiders. They're pretty cute.
And they eat inset pests for free
they eat the stuff that really annoys me. Like flies and mosquitos.
So I tolerate them and leave them alone. Never hurting them if avoidable by any means. They do their job and it benefits me.

Thats why ppl say the category of "fish" doesnt exist if you dont put every tetrapod in it.

His videos are surprising simple yet explanatory and not dumbed down of annoyingly "spectacularised".
Perfect timing! I was just wondering about their evolution yesterday
Fascinating
This is so cool. While it's common knowledge that arachnids and spiders are not the same, I never knew just how far they are apart.

Attercopus is named after an old English word for a spider, which is attercop - literally 'eight(eyed)head'
Are you certain that is the correct etymology? I was under the impression that atter was for poison, rather than for eight.
