I didn't either, but it makes sense when one considers that the crab body has evolved independently at least five times, so it's not a big stretch of the imagination to speculate that these bodies could have used that framework to evolve further into these highly adapted "leg-wings" given the immense time frame involved.

That's why it's kinda weird that so many cultures hold crustaceans as a delicacy and insects as disgusting pests. They're basically the same, the only major difference is the relatively few kinds of insects which carry human illnesses.

its obvious, shrimp basically are just sea cockroach

​@@kotarojujo2737 I've always known lobster was just sea bugs

Fun fact: People with a shellfish allergy often are also allergic to insects But anyways Insects aren’t just closely related to crustaceans, they are themselves crustaceans (at least, in the same way that you could consider us lobe finned fish). Insects belong to the clade Pancrustacea, a group that [wikipedia] ‘comprises all crustaceans, including insects’

I think you're right since he was showing a spider

​@@benisoreilly869 most likely

agreed

yea i was a bit confused by that

yeah that confused me too

I like this idea

There has been a lot of very interesting research into metamorphosis. Including producing hybrids from distantly related marine organisms with complete metamorphosis. It seems that the subject is largely ignored when portraying Evolution. (Ref: the book Metamorphosis by Frank Ryan and research from Sheffield University.)

metamorphosis always boggles me

Metamorphosis is just a shortcut in the molting process. Early insects would molt their juvenile forms and change shape subtly each time but have striking differences at both ends. Metamorphosis just fused the middle parts to one cocoon form that essentially became a second egg. Humans go through metamorphosis from aquatic to land based while in an egg. Most animals use the egg to develop. Part of the puzzle is silk but it probably has something to do with eggs and nests.

@@jeremymullens7167 There is the possibility that insects which undergo metamorphosis do have 2 genomes. (Ref a New Scientist Article). But yes, it is the same genes which are involved in triggering or suppressing moulting (Ecdysis) in Arthropods, nematodes etc including incomplete metamorphosis in insects.. Also the same genes involved in embryonic development in Chordates.

Has one of the highest success rates of any predator to ever live.

Jumping spiders have better vision, but the dragon fly has insane reaction time

@@RedSquirrelHunter jumping spiders are so cool! In summer when I'm in my backyard I can often find them and they're so tiny and SO awesome. What a very cool way to live.

You forgot that dragonflies can actually fly backwards quite easily. You can see them fly by something that catches their eye, hover and then back up to study it more closely. They don't do this a lot and not for anything but short distances but they can do it which is crazy. Hummingbirds can do this too and I am sure there are others I don't know about but I'm sure it is a very rare trait.

@@ZentaBon the diffrence is jumpers still have to "move" theyr eyes /body to see around them Dragonflys can literally look 360 ° without turning theyr head XD

Vertebrate supremacy! Jokes apart, humans are chauvinistic creatures by nature. We're way more likely to favor and be interested in those who share traits with us - be it as a person, a group, a culture or a species. Too many differences create alien hard to climb walls. It estranges us from the subject, even as it fascinates the observer.

They are so facinating and mysterious since they're hard to fossilized.

I think it’s because a lot of people have a natural aversion to bugs

True

Well that's very possible that the insects NEED to escape dryings streams and ponds, it doesn't mean they can order a pair of wings to do so on Amazon even if they lived in the amazonian jungle.

There are primarily flightless insects who are fully terrestrial on all stages.

I think part of that is their low extinction rate. Vertebrates always get hit hard by extinction events but insects just seem to stick around and get more and more specialized.

Jesus is amazing !

​@@doburu4835Jesus couldn't have even known about biological evolution because he was born and died thousands of years before modern science.

@@TheVideoIsLongEnoughhe is the creator of course he would know.

That’s a vibe

I do think the volume of the music is a bit too low compared to the past. Nonetheless still great music choices!

I prefer the music he used in his early videos

I agree the music along with his voice makes it a very relaxing journey I wonder what the music used in this video is

Yes, most excellent video production. Very pleasant and informative. Some channels are interesting but grate on your nerves. Few manage to strike such a great balance. Journey through the Microcosmos and GK Natural History are the only two similar natural history channels that come to mindthat come to mind.

Nah the old videos with Dreamer was much better

PBS Eon has a video up on this for like 2 years Just an fyi

What about PBS Eons though?

Every person undergoes metamorphosis, just at different speeds. Let that sink in.

I read the wikipedia page on insect evolution recently and it did talk about metamorphosis, I’ll summarize what it said and what I believe, although all this should be taken with a grain of salt. The silverfish and bristletails do not undergo any metamorphosis but eventually a group would sprout from their ancestors and that group would gain some things as it aged, the biggest being wings (this group being the hemimetabola, incomplete metamorphosis). This made the adult form of the organism the most ideal when compared to the juvenile form as the adult form would have flight and another abilities. This would then begin the selective pressure for organisms that aged faster. It then becomes advantageous for that final molt when the insect gains flight to also include other changes, and for some of the earlier molt to be removed. Eventually very few molt would happen and that final molt would be much longer than normal, this would make that molt extremely vulnerable and would then lead to selective pressure for a harder exoskeleton while this final molt occurs. Eventually the only purpose for early molts would be to get larger meaning that the many body changes would be shoved into the final molt. That final molt being so long and dramatic would then make it be considered an entire new stage of life, the pupal stage. Technically by this point the holometabola (complete metamorphosis) would be created but I will add one last thing. A new selective pressure would be made, the competition for resources between adults and juveniles could now be destroyed. The adults would now evolve to fit one niche while the juveniles would evolve to fit a different niche, and as the two ages adapt more and more to fit different niches it would lead to the huge change in body structure that we see with butterflies, beetles, neuropterans, etc.

Weta can't fly

@@stephenlitten1789 I googled "weta bug" and found a picture of one eating a carrot!!!!

@@kai_fatallysapphic The common ones are about 4"/100mm long fully grown

@@stephenlitten1789 they're a little scary, I've always had an irrational fear of locust-like and cricket-like insects, but also so adorable how it was just eating a carrot 🥺

he mentions ants as flightless but many ant species have morphs that are capable of flight, usually for the purpose of starting new colonies in different locations

That's Yi Qi right? I may be wrong but I believe it is still debated whether they ever reached the point of true flight or if they were still only gliders because we still haven't figured out how strong and thick their wings are

have you looked at that thing haha? doesnt seem like it could fly at all. But it is true that within the group avialae active flight probably evolved multiple times, check out the paper by pei et al. 2020

Bats, birds, pterosaurs, insects, flying fish more of a glider

@@RedSquirrelHunter Well, its debatable if that could be called a "flight" since at least as of now they aren't fully aerial, but I never thought of gliding fish. It would be cool to know the origins of them.

@@RedSquirrelHunterGliding doesn’t count. There are many types of gliding mammals today but only bats are true flyers. Gliding is probably a prerequisite to flying though.

And they're herbivore while dragonfly is carnivore version

probably

Jewel wing damselflies. Cousin to dragonfly; completely gorgeous, slightly different morphology and habits. Love seeing them!

And he said insect were crustaceans but they had separate branches. Little confusing

Actually, arthropods are now officially divided into just two subphyla, Myriochelata and Pancrustacea, myriapods are actually more closely related to chelicerates than to crustaceans, which on the other hand are more closely related to hexapods, myriapods have much more in common with chelicerates, while crustaceans have more in common with hexapods.

They wouldn’t have the energy or the need for powered flight. Fish can’t stay out of water for that long.

Some culture eat bugs

Pollen didn't exist at that time, in fact pollen is really weird: its actually not plant sperm but like a sort or separate thing that then releases sperm or something like that i don't quite know the details.

@@astick5249 how do you know pollen didn't exist at the time?

Why would an insect want pollen

@@jamestang1227 go ask bumblebees.

@@astick5249 edit: according to wikipedia earliest fossil records of pollen date to devonian period between some 400 million to 350 million years ago, the same period in which insects developed flight.

Or they will go extinct cuz of us

​@@thunderred5263 that would require incentive for those aninals to take those adaptations, which would require specialisations that could damage their fitness in other regards such as climbing, feeding or walking. Its never the goal of gliding animals to eventually fly, and there are already a lot of animals which are perfectly adapted to flying that would compete heavily with them.

@@raymond8920 ok,understandable have a nice day

Forget that, I'd rather have flying frogs!
