Why did the Neanderthals go extinct?

This is a question that won’t stop popping up. And right now I am going to take 10 different points one can make as potential answers. Let’s remember also that there is a chance that the rh negative blood factor could potentially come from a group of Neanderthals. This of course has never been proven and at this time we can only look at the Neanderthals and find certain attributes that might inspire us to look into their direction, but cannot claim we know anything. For the sake of argument and for future reference however, I will in this article go as far as drawing potential relations between Neanderthal DNA and rh negative blood and however research turns out in the future, this will be limited to what we know and all further notions are going to be indicated as such.

1) Neanderthals hated the cold.

I am assuming that Neanderthals understood that going in certain directions meant headed for either warmer or colder weather. Of course, confusion had to kick in when reaching higher elevations down south.

According to Live Science:

Many of their fossils have been found in caves, leading to the popular idea of them as “cave men.” Like humans, Neanderthals originated in Africa but migrated to Eurasia long before humans did. Neanderthals lived across Eurasia, as far north and west as the Britain, through part of the Middle East, to Uzbekistan.

This sounds strange because one would think if indeed Neanderthals originated in Africa, some would have survived there. Aside from the Yoruba, Africans have no traces of Neanderthal DNA.

The earth has gotten colder and many believe that Neanderthals were unable to handle the colder climate. In terms of relating this to rh negative people, I can speak about me and a few people I know of who have a very tough time handling the cold.

This is something that I have been discouraged from referencing, but as I am not claiming anything in relation between Neanderthals and rh negative blood as fact, let this be something that stands as is until being further examined.

2) Neanderthals have never gotten extinct.

Imagine our world in 200 years with borders opening. Do you think ethnic groups will exist then? No. The world will not be so different in looks according to location but rather people will look similar all over the globe.

Currently, 743.1 million people live in Europe.
1.216 billion in Africa.
An unbelievable 4.436 billion in Asia and 1.002 billion in the Americas.

Let’s assume that the European look as we know it will disappear. Do you think a few thousand years from now people will find our remains and wonder what happened to us?
The answer is nothing happened.
The people of the earth came together more and more to form one group.

Members of our species had sex with Neanderthals much earlier and more often than previously believed, according to a new study of ancient DNA. As some of the first bands of modern humans moved out of Africa, they met and mated with Neanderthals about 100,000 years ago perhaps in the fertile Nile Valley, along the coastal hills of the Middle East, or in the once-verdant Arabian Peninsula. This pushes back the earliest encounter between the two groups by tens of thousands of years and suggests that our ancestors were shaped in significant ways by swapping genes with other types of humans.

Reference: Humans mated with Neandertals much earlier and more frequently than thought

Europeans make up less than 10 percent of the world’s population.
About 2 percent of Europeans’ DNA is said to be from Neanderthals, even though it seems that amongst the community of rh negative people, the percentage is quite a bit higher.

If the gene pool of the world melted into one pot with less than 10 percent identical to that of Europeans today, would it be accurate to consider Europeans going extinct?
Where is the evidence of Neanderthals dying en masse?

The question now remaining is how many Neanderthals lived in Europe and Asia during the end of the Neanderthal era and how many other hominoids did as well, including today’s homo sapiens.

Then and only then can we get an accurate idea over whether or not Neanderthals died in a process of extinction with few mixes surviving vs. simply their gene pool being outnumbered in the long process of the world coming together in terms of mating and reproducing.

As I have highlighted in a previous post, it is possible that there are certain physical characteristics in Neanderthals frequent today in rh negative people.

So IF the rh negative blood factor came from a group of Neanderthals, could it be possible that those traits were passed on alongside the rh negative gene?

This is speculation in terms of how scientists are used to approaching these matters. And it would be accurate to call it no more than that hadn’t I seen what I have seen. But let’s end the speculations why Neanderthals have gone extinct.

3) Cultural superiority of humans.

Archaeologists argue that the replacement of Neanderthals by modern humans was driven by interspecific competition due to a difference in culture level. To assess the cogency of this argument, we construct and analyze an interspecific cultural competition model based on the Lotka−Volterra model, which is widely used in ecology, but which incorporates the culture level of a species as a variable interacting with population size. We investigate the conditions under which a difference in culture level between cognitively equivalent species, or alternatively a difference in underlying learning ability, may produce competitive exclusion of a comparatively (although not absolutely) large local Neanderthal population by an initially smaller modern human population. We find, in particular, that this competitive exclusion is more likely to occur when population growth occurs on a shorter timescale than cultural change, or when the competition coefficients of the Lotka−Volterra model depend on the difference in the culture levels of the interacting species.
