It's cool that, as we're nearing our end, we're at least learning more about the beginnings. Sort of has a poetic beauty to it.

Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

I'm hoping that, in our hubris, we'll re-create the environment that allows dinosaurs to rise again.
Birds inherit the Earth.
Even now and then it just catches me how absolutely insane it is how long the planet sustained complex life without any humans whatsoever. We're an evolutionary accident. A footnote consequence of unlikely circumstance. Were it not for a number of unlikely destructive events this planet might have quite happily continued ad infinitum with only dinosaurs on it. Can you imagine that, if this whole universe had happened and this one random blue marble had dinosaurs on it and not a single minded being anywhere to appreciate the magnificent insanity of it all?
I believe there's some thinking now that dinosaurs weren't doing all that well, stagnating, so without a meteor and volcanic activity they still would have changed in some manner eventually. But perhaps not enough to let the mammals fill any niches.
What gets me is how long life was on Earth just as single cell forms, and then suddenly, recently, it took off to bigger things.
The step from single to multicellular life forms is a metasystem transition, and those don't roll back, and are amplified by branching growth at the penultimate level^1^.
Or, more concretely: A strain of cells learns to communicate with each other, to coordinate, giving all a fitness advantage in other words they create a control system to regulate the lot of them and apes together stronger than apes apart. The emergence of that (usually distributed) control system is a metasystem transition. Because that kind of cooperation has advantage over not cooperating like that, evolution never goes into the other direction (in that sense it has a direction, similar to how time doesn't really exist in physical microstates, only in their relationship to macrostates: It's not like genes can't drift in the other direction, it's that if they do they get culled at a much higher rate).
And because our critters now have an advantage, they have more resources to develop, to multiply both in absolute number, as well as to specialise into different functions. That's the branching growth at the penultimate (that is, below the control system) level, and it makes them even more fit. Branching growth is one of those cybernetic laws that happen again and again and again and again and you'd think "surely this can't always be the case" and yes you'll find exceptions but by and large, yes, once there's a metasystem transition you get that effect, again, because it's very regularly beneficial to the whole.
If that got you consider the evolutionary step from soup of chemicals over the first feedback systems made out of simple molecules creating environments benefitting their own replication to actual cells. Which is explainable by chance alone, but once you take metasystem transitions into account suddenly it doesn't take an eternity, any more, only aeons.
^1^ I should, possibly, at this point warn about Principia Cybernetica just as people warn about tvtropes. It's a rabbit hole.
At the time of the K-T extinction, we looked like this:
https://en.wikipedia.org/wiki/Purgatorius
The Cretaceous–Paleogene (K–Pg) extinction event,[a] also known as the K–T extinction,[b] was the mass extinction of three-quarters of the plant and animal species on Earth[2][3] approximately 66 million years ago. The event caused the extinction of all non-avian dinosaurs. Most other tetrapods weighing more than 25 kg (55 lb) also became extinct, with the exception of some ectothermic species such as sea turtles and crocodilians.[4]
Omnivores, insectivores, and carrion-eaters survived the extinction event, perhaps because of the increased availability of their food sources. Neither strictly herbivorous nor strictly carnivorous mammals seem to have survived. Rather, the surviving mammals and birds fed on insects, worms, and snails, which in turn fed on detritus (dead plant and animal matter)
Luckily, great-grandaddy squirrel-critter was a survivor and had a taste for insects:
It is thought to have been rat-sized (6 in (15 cm) long and 1.3 ounces (about 37 grams)) and a diurnal insectivore, which burrowed through small holes in the ground.
Some birds are pretty intelligent.
Yeah but on the other hand, big numbers on a screen.
What?! Pre-squid?! This is an outrage!
The Missing Ink
I will have you know that the world was created by The Great Squid in 7 days approximately 60 million years ago.
Give me time and I will tell you about how he had a squid gather up all the life in the sea two by two and put them in a big aquarium after the Great Squid punished the wicked by 40 days and 40 nights of no rain.
Get dunked.
The Great Flying Spaghetti Monster created the Universe and all that exists, out of boredom, after indulging into too much beer.
Findings like these is just the GFSM messing with our colective hubris of knowing-it-all.
Those "fossils" were placed over night as decor, now that the ice melted.
Amen, brother! 🙌
Really should have gone with 8 days.
7 would have been fine if you land dwellers hadn't decided that you were allowed to make babies too. No one gave you permission.
Correction in your summary, they date back to 280 million years, before the dinosaurs. Not 280M more years. That would be very old.
