So how did the homo sapiens neanderthalensis nterbreed with homo sapiens?Neanderthals were also Homo sapiens. All humans today are Homo sapiens sapiens whereas Neaderthals were Homo sapiens neanderthalensis.

The usual way.So how did the homo sapiens neanderthalensis nterbreed with homo sapiens?
But they’re not homo sapien sapiens.
Unless they had “In vitro fertilisation” back then![]()
How would we ever know for certain one way or the other?Did Neanderthals have souls?
But they could have buried their dead to keep from drawing predators too; we don’t know.There is ample evidence for deliberate burials with grave goods - also artwork and objects which could have had spiritual/religious significance - which might reflect a moral conscience as well as recognition of a higher power. Based on all that, I see no reason to say that Neanderthals didn’t have rational souls.
Ed, even in your article is says “humans and neanderthals” interbred, meaning neanderthals werent human.
It is possible for two different species to interbreed. For example, a male donkey and a female horse can interbreed and produce an offspring which is called a mule even though donkeys and horses have a different number of chromosomes. But mules are usually infertile as a result.But they’re not homo sapien sapiens.
No evidence of Neanderthal mitochondrial DNA has been found in modern humans.[11][12][13] This would suggest that successful admixture with Neanderthals happened paternally rather than maternally on the side of Neanderthals.[14][15] Possible hypotheses are that Neanderthal mtDNA had detrimental mutations that led to the extinction of carriers, that the hybrid offspring of Neanderthal mothers were raised in Neanderthal groups and became extinct with them, or that female Neanderthals and male Sapiens did not produce fertile offspring.[14]
Recent studies found the presence of large genomic regions with strongly reduced Neanderthal contribution in modern humans due to negative selection,[4][9] partly caused by hybrid male infertility.[9] These large regions of low Neanderthal contribution were most-pronounced on the X chromosome—with fivefold lower Neanderthal ancestry compared to autosomes—and contained relatively high numbers of genes specific to testes, meaning that modern humans have relatively few Neanderthal genes that are located on the X chromosome or expressed in the testes, consistent with the known fact that male infertility is affected by a disproportional large amount of genes on X chromosomes.[9] It has also been shown that Neanderthal ancestry has been selected against in conserved biological pathways, such as RNA processing.[9]
Genes affecting keratin were found to have been introgressed from Neanderthals into modern humans (shown in East Asians and Europeans), suggesting that these genes gave a morphological adaptation in skin and hair to modern humans to cope with non-African environments.[4][9] This is likewise for several genes involved in medical-relevant phenotypes, such as those affecting systemic lupus erythematosus, primary biliary cirrhosis, Crohn’s disease, optic disk size, smoking behavior, interleukin 18 levels, and diabetes mellitus type 2.[9]
en.wikipedia.org/wiki/Archaic_human_admixture_with_modern_humansIn a 2013 study, researchers found Neanderthal introgression of 18 genes—several of which are related to UV-light adaptation—within the chromosome 3p21.31 region (HYAL region) of East Asians.[16] The introgressive haplotypes were positively selected in only East Asian populations, rising steadily from 45,000 years BP until a sudden increase of growth rate around 5,000 to 3,500 years BP.[16] They occur at very high frequencies among East Asian populations in contrast to other Eurasian populations (e.g. European and South Asian populations).[16] The findings also suggests that this Neanderthal introgression occurred within the ancestral population shared by East Asians and Native Americans.[16]
The argument I’m making is (a) different species cannot interbreed, and (b) the fact the some modern humans have Neanderthal DNA means they could interbreed with homo sapiens sapiens. That’s it.Ed, even in your article is says “humans and neanderthals” interbred, meaning neanderthals werent human.

But the neanderthals werent human. Your article even more or less says so.
So horses and donkeys which can interbreed and produce mules are not a different species even though they have a different number of chromosomes?The argument I’m making is (a) different species cannot interbreed
There really isn’t a consistent, universal, no-exceptions-possible way to define a “species”. Yes, horses and donkeys can produce mules, but mules are generally infertile. Lions and tigers can interbreed, but there are still good odds that the offspring won’t be fertile. But grizzlies and polar bears - as well as coyotes and wolves - can interbreed, and their offspring are almost universally fertile and breed true with each other.So horses and donkeys which can interbreed and produce mules are not a different species even though they have a different number of chromosomes?
Based on the above, then shouldnt the neanderhal/human coupling resulted in infertility?There really isn’t a consistent, universal, no-exceptions-possible way to define a “species”.

A “species” is simply a bucket into which biologists can put groups of animals with similar traits.
Obviously not.hen

They werent human, though.Obviously not.
Ed
what does homo sapien mean?They werent human, though.
Yes, they in fact were. Just as we have different racial types today with the most noticeable differences being facial angle and facial construction, Neanderthals fit the profile of a racial group. Pygmies aren’t human?They werent human, though.
In your link the writer said humans and neanderthals.Yes, they in fact were. Just as we have different racial types today with the most noticeable differences being facial angle and facial construction, Neanderthals fit the profile of a racial group. Pygmies aren’t human?

I would love to know why.I don’t find Ken Miller credible.
