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.

Goddammit, stop playing with fire, scientists!!
In the Jurassic period there were giant insects like dragonflies with 4ft wingspan. Turns out THIS is how we get to Jurassic park
Insect body size is dictated by oxygen levels, and since they absorb oxygen through their skin if they get too large with too little oxygen they suffocate.
Carboniferous period. Jurassic was about 100m years later.
Carboniferous Park
Shit was fire (30% atmospheric oxygen levels)
35%, even. It's more like 20% today, for comparison.
Let's make s movie!
It was a wild guess and I was hoping someone smarter than me would correct me ❤️
In my defense the dinosaurs from Jurassic Park came from wildly different eras so Carboniferous super bugs can still fit in!
I just asked ChatGPT because I knew something was off.
Yeah and human-sized scorpions
You are thinking of sea scorpions who for one werent scorpions and for two were aquatic in nature only going onto the pre carboniferous land as a shortcut since there was nothing on land.
Not unless the level of oxygen in the air goes up dramatically, that's what allowed those big bodies when they had no lungs
Isn't that Lamarckism? If I recall correctly, that's an older model of evolution that is not commonly recognized anymore.
slightly stronger ones survive to pass their genes to their offspring, that's the idea.
Natural selection is usually implied. So, in long form, smaller insects would have to be less reproductively successful, and that's hard when you're a pest that really benefits from being tiny, stealthy and energy-economical.
