When it comes to creative methods of catching prey not many animals are able to rival spiders. Not just being among the small group of animals that create traps to catch their prey but also having many different methods of trapping the prey. And central to nearly all their trapping methods is their ability to spin a web. However, the way in which they do this is evolutionary puzzling because the way they catch their prey is quite advanced and it seems that the precursor to these abilities: just the ability to produce silk, would be useless to hunt creatures on its own. So how did spiders develop such complex prey catching abilities

What impresses me even more than the evolution of spiders spinning silk? That someone was able to find and identify a single strand of fossilized silk. Some of these trace fossil discoveries are mind-boggling that we were able to not only find them, but also realize they weren’t just random bits of rock.

Big fan here, you are my favorite evolution channel on youtube! This isn't a correction as much as it is just a cool little tidbit I'm not surprised you were unaware of when putting this vid together. So at 4:42 you say spiders are the only animals that use their silk to make complex structures, but there are actually several species of caddisflies in the family Hydropsychidae that spin debris-catching nets as aquatic larvae. They feed on the organic materials carried by stream currents which get caught in said nets. I just did a quick google image search and several of these nets are highly organized, resembling a chain link fence or fishing net material. There are also some caterpillars in the family Urodidae that spin these trippy cages of hardened silk in which to pupate, which I would consider very geometric and complex.

@FalandraAoC Год назад

I find it fascinating how spiders spin their webs. On my balcony I observed a spider spin her web, she made such a nice shape and I loved seeing how intricate her work was with the smaller and smaller spaces towards the middle. Master craftsmanship! Years ago I wasn't a fan of spiders at all, probably even scared but somehow, the Arachne myth from ancient greek mythology made me appreciate them and their webs, because it's actually a quiet sad story with a somewhat beautiful (yet still sad) ending. I always think of it when seeing a spider make her web 🙂

@PhoenicopterusR Год назад

Then you have spiders that make tangle webs, very messy but almost a DnD-esque level of trap.

@thomasevans3387 Год назад

Complex webs are also made by insect groups as well. Many Trichopterans spin extremely complex silk webs which they use to fish with (if you are interested there are excellent pictures of Hydropsyche webs on Google). It may be that in the terrestrial habitat spiders occupied this niche early, and that later groups did not have an opportunity to exploit it. Let me also add, that the evolution of spider webs could have been ground up, with species making more and more arboreal webs later. As you pointed out, modern primitive spiders are ground dwelling and do use silk to varying degrees. Our early knowledge about insect flight is extremely limited, but presumably they used it mostly to hop, skip, and jump around, not long flights like we think of. The other thing to keep in mind about this is that there were no trees, so most things were happening at much lower levels. Later as trees grew up and insects appear to have followed spiders may also have gone up with the trees, in a sense being lifted into the air by the vertically expanding ecosystems. This is a nice video thinking about an important group, thank you for posting it.

I would think that spinning silk evolved first as a way to create and protect egg sacks. If I had to guess, it was sort of like how caterpillars create a cocoon. I was simply a way to protect their eggs. Eventually, they used it on the ground to catch things. Eventually moving upwards to catch bugs in flight. Of course, this would have happened over many many many generations. But, that's just my guess.

Having a stable home world for a hundred billion years you could become a god to most civilizations. We are a few hundred thousand years old and have conquered this planet and been to the moon. Our society is around 20 thousand years old. There has to be planets with societies millions or billions of years old.

Spiders aren't just locked into an evolutionary arms race to build better webs with insects but amongst themselves also. Since building webs is their way of acquiring food, a more efficient web is a direct competitive advantage against other spiders and their own species most of all, because the spider that gets the most food on average is healthier, has a better chance of reproducing successfully and has healthier offspring.

Eggs held together in silk eggsacks may have had an evolutionary advantage since they're less exposed to the elements. Silk could be used as a bungee cord to avoid death when jumping at prey. Strands could dangle in high traffic areas and catch bugs. Silk threads can be used as a parachute in order to travel long distances in the wind. Those are my theories at least. It's all behavior that spiders we see today perform.

It's cool seeing how industrious spiders can be when they fastidiously spin a new web daily after dusk. I try to avoid breaking a spider's web when I'm out on nighttime walks, knowing how much work they put into them.

Finally the first comment, great video

Great video, lots of information. Learned lots, thought the video would be over soon, was only half way. Keep it up.

i really want to see more than anything what the ordovician period looked like. prototaxites and insects roaming around in abundance would be crazy. id love to see an accurate artist rendition.

You are so informative and engaging. There is one thing I want to learn, how venom (not symbiote) evolved, which is the first animal to use venom etc…

@williambrandondavis6897 Год назад

Good question. Maybe from the Paleozoic era. Urchins, corals and jelly fish existed then but I don’t know if they were venomous.

I love these videos. Nicely made, relaxing, interesting, calmly and tastefully spoken voice and excellent images and sound. What’s not to love ? 🙂

Not me having a laugh at the creationists in the comments

@FakeMoonRocks Год назад

I'm laughing at the notion of forests 300 million years ago resembling modern day rainforests. People will accept that massive creatures like Dreadnoughtus existed, but they also believe they walked among relatively tiny trees the size of what we have today. Meanwhile, there's evidence of massive fossilized trees with large cellular structure that mainstream science writes off as natural geological formations, the result of molten rock ejecting from the Earth's crust and cooling in such a way as to create the column structures that would be the truck of large tree species. Somewhere in the mythology of it all lies the truth. Devil's Tower, Wyoming. It's the petrified stump of a once tall, maybe sprawling, or both, giant tree. I don't buy their mainstream explanation.

@@FakeMoonRocks y'know, if you're so convinced that evolutionary biologists have it all wrong, maybe you should study to become one. As of right now, research in evolutionary biology doesn't care about your opinion.

@FakeMoonRocks Год назад

Except I said no such thing. Interesting that you get to say that about me, but my comment doesn't appear. Zero context with this thread now. My comment went beyond evolutionary biology. It included geology. The challenge is to geologists to show a modern example of molten rock behaving the way they claim it did.

@@loucam-l6214 It's a problem, because now someone can run with this claiming I had some kind of fundamental objection to your original comment, paint me as a crazy, zealot who thinks the planet is 6,000 years old.

Even though I have arachnophobia and I jump out of my seat and squirm at them even into adulthood. They are very fascinating creatures and this was a cool watch!
