This combined with PBS Space Time just brings back good memories of old Discovery Channel. Before it got filled with ice road truckers and deadliest catch. Back when new sciences were being shown.

[@richardcramer1604]

A Diabetic Jedi, I agree the Discovery Channel and History channel were great in the 1990's and early 2000's but then to save money they started putting all those boring reality TV shows. The only saving grace was The Universe series but when History started showing Ancient Aliens I jumped ship.

[@metanumia]

Honestly, I have more respect for trilobites than the dinosaurs or even fellow mammals as survivors. They didn't need to become towering giants or legendary predators, they were just little toughies who were only wiped out by the closest event to the actual apocalypse that the natural world has ever known (with the ancestors of the dinosaurs and mammals only _barely_ surviving it, and they weren't even already on the ropes like the trilobites were). Rest In Peace, bold bugs. Hopefully, when reviving extinct species has been mastered, they'll be among those brought back again for round two at what they do best; adaptation and survival.

Regarding the ability to enroll: this may not have originally evolved as a defense against predation, but rather to improve their ability to moult. There are fossils of trilobites that died in the middle of moulting, apparently getting stuck on the way out of the old exoskeleton. Being able to significantly flex their body up and down probably allowed them to dislodge from the old exoskeleton much more easily. This flexibility could later be coopted to fully enroll as defense

Trilobites must be cloned!

[@bemusedbandersnatch2069]

...cloned how? Cloning requires DNA. They died off many millions of years before the dinosaurs. Furthermore, what remains we have of them are all fossilized. We can clone mammoths because we've found mammoth bones and I think a frozen mammoth or two (Google says yep, that's a thing.) Jurassic Park came up with the hypothetical process of cloning dinosaurs from dino blood in a fly in amber (which I think is impossible given the lifespan of DNA but I digress). But...there's nothing from that far back that left any biological material behind that I know of. It'd be like trying to clone a human from a photograph. So, we'll whip them up from scratch someday once we finally commit the greatest blasphemy of all and start cooking up brand new forms of life for our own amusement. EDIT: And after I wrote this silly comment I went 'a googlin' on the subject because I was curious. Apparently some team managed to analyze a 500 million+ year old fossil and figure out that it had cholesterol and was thus an animal. So apparently science is even more crazy awesome than I thought and maybe we will have cloned trilobites someday. Who knew?

And clearly Ashley Clark has a curious enough mind, that it brought her(him) to this video and was enlightened... One can now hope that from this new enlightenment that she(he) will seek other new things like this... For learning more things like this, I would highly recommend anything from SIr David Attenborough.. He has a great 2 part series called "First Life" which goes in good depth on early life on this planet... Just do a search using "David Attenborough's First Life" He has so many docs out on life and animals... Great ones.. He's been doing it for over 50 years...

[@juanstevanordonezvillota653]

The title of this video made me remember a Star Trek episode called “The trouble with the tribbles” in the original series...

[@crazycatlady39]

0:19 "They're known the world over because they were everywhere!" Sounds like the original version of Cockroaches.

[@sunnyalphax3539]

Seems like they were just as hard to kill too.

[@crazycatlady39]

@@sunnyalphax3539 Four hits from Life itself?!? Yeah, definitely qualifies.

[@Jack-yq6ui]

Trilobites, or what I like to call, my Trilobuddies.

[@jam5533]

I'll always find trilobites as cute and unique! :D

[@GiantEnemyMudcrabz]

Its always nice to learn about your ancestors. Thanks PBS!

[@nanababytwa]

He did say that they didnt leave any descendants. sorry but they are gone for good.

[@vulpinelinguini]

Love to see this guy, he taught me anatomy while I was in Massage Therapy school.

[@natrodgers9267]

YES! Can't wait for this!!

[@daphneloose5880]

love the Star Trek reference in the title!! I am surprised that the trilobites are still not with us. you would think that they could survive anything. R.I.P. trilobites.

[@rachel_v_k]

Great video! I enjoyed learning about the trilobites. I had no idea that there had been so many types or that they had existed for so long. Thanks for the info! 😊

[@apollion888]

Brilliant writing The delivery was good as always but the writing this time was close to flawless

[@lunakm764]

Extinct species from millions of years ago tbh make me sad. They are so cool. I wish we could see all those animals. Trilobite is beautifyl

[@camdenhill7651]

I'm already Digging this

[@abhiramsrivastava4601]

Camden Hill I'm already hating you for that joke Naw jk bruh 😂

[@pbsvoices]

ba dum chiii

[@Infernoraptor]

I dig it like Diglett

[@metanumia]

Hope you find some good fossils. ;)

[@blobbertmcblob4888]

Do not worry lil Trilobites. We still have Horseshoe crabs and Triops.

[@messier8379]

Yeah the Blue Blood of Horshoe Crab are immune to all kind of Bacterias and Virus..this might explain how they survived From Great Dying....problem is Humans is Harvesting their blood for Medicines and Vaccine...Humans could be the another Footnote for them

[@lexlex44]

Even tough biology is not like technology, it doesn't mean that it's not full of mechanisms, things that you can control directly, just influence, like digestion, heartbeats, regeneration, growth ,mechanisms that helps and maintain youth\longevity, hearing, skin sensing, thermal sensitivity, pain receptors, and so on ! But a thing that always strikes me id the complex mechanisms the eyes had on visualizing things and the ability to focus on what it sees ! When I realized this I KNEW that it wasn't a mechanism that just developed overnight, and when I heard that there were creatures with eyes of stone that basically could not focus due to this it made sense ! Having eyes that can focus is a really new thing, it wasn't always there !

[@tomperone9338]

One of my favorite Star Trek episodes! Remember when Kirk opened that grain bin and all those Trilobites fell on him? 😁

[@electricalmayhem]

I love More Tribbles, More Troubles when they tie back into that episode. The whole Klingon thing is hilarious.

[@Lazerblade95]

So glad this is happening.

[@indigoray6693]

Richard Kaskiewicz you're so glad what's happening?

[@indigoray6693]

Jess Vermont and what did you mean by you're having trouble with their trilobites and hoped nobody noticed what? Lol sorry I'm just a little confused on what u mean.

[@LuisSierra42]

Richard Kaskiewicz, What, another massive extinction?

[@johnishikawa2200]

Whenever I see horseshoe crabs I think about trilobites . Horseshoe crabs have blue-green color blood , and I have seen many of them moving seemingly locked together in a raft formation , in the shallows just about a foot below the water surface . I believe that they are laying eggs near the beach . But there must be thousands of those horseshoe crabs in that raft of them .

[@SheoTheFox]

i wish trilobites still existed

[@raver4lyfe16]

Horse shoe crabs are pretty close

[@mdawson8386]

They do still exist just as fossils!

[@randybarnett2308]

Sheogorath2077 me too I wonder if they taste like shrimp?

[@rollomaughfling380]

04:33 That is one seriously goth trilobite

[@mnessenche]

Trilobites Never Forgotten 😢

[@LMAccount1]

This is great, thank you

[@ivandelarosa9408]

That spiky one was Gnarly! Imagine seeing these things in real life! :D

[@EduardoLopez-tged]

I am glad he mentions that we should think of the trilobites as a success story, they lasted 300 million years and it took the worst possible catastrope to finally do them in. He says humans are a success story but we have only been here for a million years in some form or other and we are on the cusp of damaging our eco system enough that it could harm us. Let says it takes another couple thousand years before humans can't live on the planet, we will have not even 1% of what the trilobites had.

[@sussekind9717]

The difference is we have the ability to do something about it, IF we put our minds and effort into it. Come on team humans, get your act together!

[@michaelrogers5330]

Great video and series. One request...Can you please talk about how we know these things happened? Like who discovered trilobites? How do we know they lived when they did? Also, please provide sources. These videos are essential for our society, as a large segment of the population doubts the reality of evolution. It's important to show them how we know these things happened the way we say they happened.

[@pokekitty1]

one thing i would add is how are trilobites related to modern day creatures when they were all wiped out

[@Merlijn83]

I'm no expert, but I venture to guess it's the same as how birds are related to dinosaurs. They didn't /all/ get wiped out, just the vast, vast majority of them did.

[@CarlosSantos-so5ww]

Actually, they went extinct leaving no families behind. All we know about them are because of the fossils. There's no living descendant of Trilobites.

[@PGraveDigger1]

There's references in the video description, maybe those could help you out.

[@Edwardo160]

I can't wait to see how the world will be in 10 million years from now

[@soulmass8904]

I found a small one of these on a hike when I was really young.

[@ges4934]

Great show and I'm loving the Star Trek reference :)
