The Yamnaya archaeological complex appeared around 3300BCE across the steppes north of the Black and Caspian Seas, and by 3000BCE reached its maximal extent from Hungary in the west to Kazakhstan in the east. To localize the ancestral and geographical origins of the Yamnaya among the diverse Eneolithic people that preceded them, we studied ancient DNA data from 428 individuals of which 299 are reported for the first time, demonstrating three previously unknown Eneolithic genetic clines.

First, a "Caucasus-Lower Volga" (CLV) Cline suffused with Caucasus hunter-gatherer (CHG) ancestry extended between a Caucasus Neolithic southern end in Neolithic Armenia, and a steppe northern end in Berezhnovka in the Lower Volga. Bidirectional gene flow across the CLV cline created admixed intermediate populations in both the north Caucasus, such as the Maikop people, and on the steppe, such as those at the site of Remontnoye north of the Manych depression. CLV people also helped form two major riverine clines by admixing with distinct groups of European hunter-gatherers.
A "Volga Cline" was formed as Lower Volga people mixed with upriver populations that had more Eastern hunter-gatherer (EHG) ancestry, creating genetically hyper-variable populations as at Khvalynsk in the Middle Volga.
A "Dnipro Cline" was formed as CLV people bearing both Caucasus Neolithic and Lower Volga ancestry moved west and acquired Ukraine Neolithic hunter-gatherer (UNHG) ancestry to establish the population of the Serednii Stih culture from which the direct ancestors of the Yamnaya themselves were formed around 4000BCE.
This population grew rapidly after 3750-3350BCE, precipitating the expansion of people of the Yamnaya culture who totally displaced previous groups on the Volga and further east, while admixing with more sedentary groups in the west. CLV cline people with Lower Volga ancestry contributed four fifths of the ancestry of the Yamnaya, but also, entering Anatolia from the east, contributed at least a tenth of the ancestry of Bronze Age Central Anatolians, where the Hittite language, related to the Indo-European languages spread by the Yamnaya, was spoken.

**We thus propose that the final unity of the speakers of the "Proto-Indo-Anatolian" ancestral language of both Anatolian and Indo-European languages can be traced to CLV cline people sometime between 4400-4000 BCE. **

A lot of the larger abandoned magazines are just spam pools now. I don't see their posts in my feed, but I don't like that the two sidesbars of random posts and threads are now just spam advertising sidebars. I triedblocking the magazines, but doesn't that prevent the posts from showing in those sidebars.

Now don't get me wrong, I love it when m/infosec advertises voodoo curses and revenge spells, but after the first time the joke wears thin, you know?

I love all the ritualized behaviour, secret meanings and unexpected taboos - standing up when someone of higher status stands, elaborate rules for serving and eating, tapping the table to thank the server, never refuse a toast from a superior, stuff like that.

Whether it's about meals or anything else, I'd love to hear about any uncommon politeness standard or similar social behaviour that goes on in your location, culture or restaurant!

An undercover police officer arranged to buy 2 magic mushroom chocolate bars over Instagram then opened fire within seconds, killing the driver and injuring the passenger for selling $100 worth of antidepressants. Perfectly justified.

Interpret improvements as you like. For me it's any large scale reforms or legislative packages designed to improve the country for all or see to the material interests of the majority without overly benefiting the elite.

Any big consumer protection, environmental, infrastructure, or other legislation from Clinton onwards that materially improved the lives of all?

Obamacare and the medicaid expansion comes to my mind. It has obviously improved people's lives but considering how broken the healthcare system remains, and that it was written by the insurance industry to undermine single-payer, it seems to me a mitigated win at best.

Gay marriage and marijuana legalisation but that was the courts and the states although i'm sure the federal government could've stood in the way had they chosen to.

I've only live here since the 2010s so that's all I can think of.
