The human population bottleneck has been known about for a long time. One striking fact is that there's more genetic diversity in a typical troop of chimpanzees than the entire population of homo sapiens today, because we were reduced to such a small genetic sample during the population bottleneck.

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.

And one of those bastards is responsible for balding
And, like, half of our genetic diseases.
I don't know the actual numbers on it but it's still their fault and none of you can prove otherwise.
Whats population bottleneck?
From wikipedia:
A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts
People challenging the seriousness of the climate change are saying "we will adapt and survive like we always have".. Yeah, our "adapt and survive" could look like that.
People really don't understand what it will be like if society collapsed.. mad max is a future documentary at this point
Not really, the world of Mad Max appears to have an infinite amount of gas supply. This is very unlikely to happen in the real world.
I think it's more that the fuel supply we have on hand is now spread among a population that is 99% smaller. What would last us months lasts them decades.
Gasoline will expire after about a year...
Diesel doesn't
If at first you don't succeed...
Planet with global warming: “I didn’t hear no bell!”
Bang your sister
A genomics analysis of more than 3,000 living people suggested that our ancestors’ total population plummeted to about 1,280 breeding individuals for about 117,000 years.
We were so close…so close…sigh
Invent time travel. Get your grandfather paradox on.
I should not be trusted with such things tbh
Too bad it didn't just do it. The planet and rest of life probably been better off.
Humans to the planet in 2023: "Should've killed me when you had the chance"
“I lived bitch!”
"Who left the fridge open?"
To true. We damn sure doing our best to destroy it. Of course planet will be fine unless you find a way to crack in half and I wouldn't put it past us.
This is the best summary I could come up with:
“The numbers that emerge from our study correspond to those of species that are currently at risk of extinction,” said Prof Giorgio Manzi, an anthropologist at Sapienza University of Rome and a senior author of the research.
Prof Chris Stringer, the head of human origins at the Natural History Museum in London, who was not involved in the research, said: “It’s an extraordinary length of time.
The decline appears to coincide with significant changes in global climate that turned glaciations into long-term events, a decrease in sea surface temperatures, and a possible long period of drought in Africa and Eurasia.
However, Stringer said there was not convincing evidence for a global “blank” in the fossil record of early humans, raising the possibility that whatever caused the bottleneck was a more local phenomenon.
This is probably due to the ancestors of those of non-African heritage having in effect undergone a more recent population bottleneck during the out-of-Africa migration, which would be expected to mask the earlier event.
The timing roughly coincides with when the last shared ancestor with Neanderthals and another ancient human species, the Denisovans, are believed to have roamed the Earth.

Good bot!
Agreed, but please don't start with that spam here too.
Alrighty - I thought that was a response that the bots use? If not I’m happy to refrain
