Nah I’m just very interested in agricultural history (I work in agriculture ) and I learned this stuff as a byproduct of learning about the origins and spread of farming into Europe. If you are interested there are lots of good long-form history videos about the neolithic on YouTube, just search Neolithic. So far Neolithic youtube has not suffered the same AI slop-ageddon as medieval YouTube has.

There was a time where both modern humans and Neanderthals lived together in Europe and it’s likely they mixed. But this was before the last ice age. After the ice age the Neanderthals were already extinct globally and the first people to repopulate Europe were these WHGs who genetically had little to do with the pre ice age population. Therefore I would assume strictly European Neanderthals have little to no modern genetic impact in Europeans. The Neanderthals genes Europeans carry today would instead derive from middle eastern Neanderthals.

Modern native European genetics can be roughly said to derive from 3 main sources. One is western Hunter gatherer (WHG). These were not the first people in Europe but were the first to populate Europe after the latest ice age ended. By analysing their genome we think they were dark skinned, black haired and had blue eyes. The light skin adaptation didn’t actually develop in Europe but in the middle east. Here is where the second group comes from.

Early European Farmer (EEF) originally came from Anatolia and were the ones spreading farming around Europe. Interestingly the spread of farming was not spread by knowledge transfer but by the migration and expansion of EEFs. The EEFs and the WHGs would coexist for hundreds of years with little admixture, living completely different lifestyles. The early European farmers, whose genetics derive from Neolithic Anatolia, were light skinned, brown eyed and relatively short. Modern groups with the most genetic similarity to EEFs are modern day Sicilians so you can imagine that. Overtime the EEFs and the WHGs would eventually mix however.

The third group are the yamnaya, also called steppe Ancestry. The yamnaya were a people group in modern day Romania and Ukraine who just so happened to invent the concept of riding a horse and after they did so they steamrolled about all of Europe in aggressive conquest. The Indo European languages derived from them and their expansion vastly changed the genetics of the continent. And all Europeans derive at least part of their genetics from them, of course in different amounts depending on the region. They were believed to be quite tall and have blond hair and are the “Aryans” that the Nazis talked about.

All modern Europeans are a mixture of these 3 groups, in different proportions. So returning to the pictures in the OP it makes sense for the cheddar man would be dark skinned as he would be 100% WHG as he lives way before any of these groups moved in. This does not mean however that the guy on the right is not a direct ancestor, he very well may be. But since he is also a result of the later migrants, the EEFs and the Indo European expansion, he will of course look vastly different.

I did not know the history of the term tragedy of the commons. Thanks for educating me on that, I will now reconsider using that specific term in the future. However overgrazing is a real issue historically and still today. Overgrazing in the modern Sahel is a great contributor to the advancing of the sahara for example.

Are those generations really worse than those before it? Yes the environmental destruction is unparalleled but so were also the tools that enable that. In the Stone Age people could not have even come close to doing what we are doing right now to the environment even if they wanted too.

The term the tragedy of the commons originally referred to English cattle herders letting their cows overgraze public land because if they don’t overgraze it some other herders would do it instead. Stories like this are everywhere in history. The Vikings cut down every single tree in Iceland and the Faroe islands when they arrived with no care for the environmental whatsoever.

Whaling, the clubbing of seals, the extinction of the dodo. There are countless examples. And if we are talking pure human to human cruelty, no war in the 20th century comes close to what the mongols did.

The people of the 20th century were not more cruel or selfish than previous ones. They were simply the first ones given the tools and ability to pollute the whole earth.

My goto is explaining how a plant can in certain situations be a weed and sometimes don’t. For example in a farm which farms clover seeds the grass is the weed! In a farm which farms grass seeds the clover is a weed! Same in agriculture, stray plants from the previous years crop often appear as a weed in the current years field.
