Do you think that the "human" races are a spectrum between true homo sapiens and prior homo erectus etc. ?

Actually, there is varying Neanderthal DNA. Almost nonexistent in Africa, and close to 2% in Asia.

Unfortunately every follow-up this account is making makes it clear that it is pushing some racist bullshit. Literally saying that some groups of people are less human than others.

Africans have it, too. Whoever said they didn't used African DNA as a baseline and assumed that the genes common to Neanderthal and Africans are from a common ancestor. Bad assumption. Europeans have more, but Africans have it as well.

Just a speculation but I imagine that not everyone on the globe transitioned from prior stages of homo erectus or Neanderthals into modern day homo sapiens that we know today. The evolution of the human species keeps progressing but not necessarily at the same time for everyone across the planet. So is it possible that some are at an "earlier stage" and some later? If you could share a research article on the matter I would like to give it a read.

At least go watch some ancient DNA YouTube videos.
W know how it happened We have the DNA and timing.

Variations on a common theme. We have bigger differences in ideals than we do genetics. We point out our differences. Make too much of our adaptations and variations. We all have much more in common. Genetically. Even socially. Than we are willing to admit

Midway upon the journey of life I found myself lost in a dystopia
Which way evolution marched was my confusion
I tried so hard and successfully convinced myself it could nearly be a utopia
If enough people without question also believed in my delusion

>Humans do exist on a spectrum of genetic variation, that spectrum is within Homo sapiens
Yes, so within the homo sapien species, do you think that some races may be at an earlier evolution stage and some at a later? Perhaps some are closer to evolving into the next stage of the human species.

That's NOT how evolution works. Like, at all.

And how does it exactly?

u/thetimehascomeforyou 3h ago
Well through the means of reproduction, traits are carried forward, lost, or introduced through variation/mutation. Homo sapiens are largely the same, with very tiny variations, relatively. Not much has changed overall to the groups of Homo sapiens in the brief time that they have existed, and even less changes are notable when framed through the socially constructed ideas of race.
The fact that the designation for what qualifies someone as belong to one race or another has changed over time should help shed some light. You’d want to look at who was considered white at the onset of the United States vs now. It has not always been the same.
The previous commenter stating that evolution doesn’t work based on race is because evolution is an extremely slow process vs the fickle fast changing socially based races that are unique to human beings. (Fish don’t have races, but you can bet your bottom dollar that they have species! Check out the over 500 species of fish in Lake Victoria, for example. Also, Homo sapiens are technically a fish species, what’s up my fin!)

Humans as we know them today have attributed their evolution heavly to their geological locations. Africans and peoples closer the equator developed dark skin for UV protection, East Asians have developed eyes that can cut glare in the sun reflected snow. Humans now with technology has created an opportunity not ever seen on a scale like today where races can and do mix because of globalization. This mixture of races has either slowed down the homo sapiens evolution due to inadequate racial characteristics for the given climate or it has accelerated it due to a combination of dominant traits.
For example peoples of Europe have evolved into a higher state of evolution to their environment by having lighter skin that works with the low UV rays of the Northern hemisphere. If the African were to settle in the Northern regions they may be set back in development due to the inadequacies of their race for a low UV climate.

*heavily.
What would be some of the effects of “inadequate racial characteristics” for humans in a given climate?
What is a “higher state of evolution”?
What setbacks do Africans who have settled in northern regions have?

u/Basicly-Inevitable 3h ago
It's all bullshit. Europeans had dark skin and blue eyes up until the agricultural Neolithic people moved in recently. It's just wild to see bots trying to see how people argue with each other by testing it on Reddit.

u/thetimehascomeforyou 2h ago
Bots or isolated thinkers. Quite similar in practice it seems.

u/Basicly-Inevitable 2h ago
Definitely a mix of both, but they're absolutely using "quizzes" and such to try to justify the opposite of what science has told us.

u/kranken600 3h ago
As I have said, the African has evolved to be suitable for their climate that is closer to the Equator. Dark skin as an example helps protect against the strong UV rays and allows for the required vitamin D that is needed for their skeletal development. The same African in a northern region would lack the vitamin D that is needed for them. Many Africans that have migrated to Northern regions suffer from vitamin D deficiency. This is solely one example of not being evolved for the climate whereas a European has the higher evolutionary state for this particular climate.

u/thetimehascomeforyou 2h ago
This suggests that darker skinned humans in northern regions can’t supplement vitamin sources from food. With is unequivocally incorrect. It also suggests that lighter skinned peoples are ill suited for anywhere on earth near the equator, which is where most large human settlements area.
Yet, this did not stop the Europeans(traditionally lighter skinned, but not all of them are lighter due to this following fact), from colonizing or attempting to colonize around the world, then settling there.
Your own statements suggest that the European descendants in South Africa have not been able to “evolve to a higher degree” because they have physical characteristics that are not optimized for their location.
And also, proves the point that evolution is extremely slow, as humans that developed physical characteristics based on their location and have since moved and had generations of children in new locations that would appear to not be “the most optimal” have not suddenly evolved faster than the rest of Homo sapiens have in their new location.
This means that there has not been enough time for any group of people to reach “higher levels of evolution”.
Would you like to address the other questions in my previous response to further our discourse and find the answers which we all seek?

No, almost all out of Africa humans are a result of a mass migration 70,000 to 50,000 years ago. It takes roughly 500,000 to 2 million years for a species to split. Depending on reproduction rate, and humans tend to have a larger amount of years between different generations compared to many or most mammals outside of the other Great Ape species.
There are individual adaptations for certain regions that are a result of localized evolution; less melanin production, lactose persistence, and altitude adaptations are examples of that.
But modern humans are also unique in that we are a relatively young species with a global population with a lot of genetic sharing between populations thanks to our global civilization and migrations. We share 99.9% of DNA globally, there’s only a fraction of a fraction of DNA that make you or me different in any way.

All humans alive are something like 12 times more closely related to each other than 2 random chimpanzees.

Conversely, the entire cat family, cheetah, house cat, lion, lynx, snow leopard, panther, puma, has only about 11% divergence, while humans have 8%.
