Why are we the Only Humans Left?


How come all our upright-walking relatives are extinct?

Because we killed & ate most of them, keeping only a few young females.

Can we be sure they are?

The has been the discovery of a "pre homo sapiens" y chromosome in an African American ,
his family wanted the test , he died soon after
the first results were deemed impossible , the lab requested an exhumation for taking more samples
double and triple checked but had to concede , his male ancestry was older than homo sapiens sapiens , older than Neanderthal

further research in Africa discovered in Cameroon a very small male population having this very archaic gene
their ancestors survived by hitching a genetic ride with the Homo sapiens women
I pray on my knees for a Neanderthal having survived by the same way ,
there was interbreeding , but so far it seems that the Neanderthal are gone ,
we didn't really killed them we just pushed them over a cliff

there is a great number of tribes who got exterminated by their neighbors , down to recent history
maybe we should call ourselves homo sapiens genocidicus

Could you link some sources on this?

because we're better. and that's not being puerile, but a fact.

I presume the nature of the Neanderthals' extinction was complex. it may have been like the extermination of Native Americans in the Reconstruction period. Some whites tolerated them, most killed them out, whilst the rest were placed on reservations that their descendants still live on. I don't think all homo sapiens killed all Neanderthals, and since Europeans have Neanderthal DNA there must have been some inter-mating.

We were/are better due to having better technology, and thus pushing others out due to utilising better/more resources. That said, I presume homo erectus killed off australopithecus, or homo habilis. There is a film called Missing Link which shows this, and it's pretty plausible.

In a way, this is normal in evolutionary standards. Those who don't adapt, die. New species who better exploit niches kill out those who cannot.

@ Ridiculous name ....sure ! An African American Paternal Lineage Adds an Extremely Ancient Root to the Human Y Chromosome Phylogenetic Tree - ScienceDirect

notgiveaway , you are probably right on the disappearance having multiple causes
the major one being the Cro Magnon arrival and the competition conflicts ensuing

Neanderthal were a weird bunch , in spite of living next to salmon stream it seems that they didn't fish
we know from interlacing deposit of their grotto floors that when bears lived there there was fish bones , when the Neanderthal were there , there is none
they had bigger brain than us , the cross section of their bones indicate an astounding muscular strength
those guys could have thrown a small sized bison on their back and brought it home
they had no throwing weapons ,bows or animal companion
an analysis of the type of their their injuries is equivalent to rodeo riders
it would seems that their hunting technique was to get close and personal

Never numerous , the classic western type was very evolved and could have suffered from genetic dead-end syndrome
there was some interbreeding with cro magnons but it seems that was only for women
bands of young hunters would have sex with anything , kill the men ..shag the women
repeat again and again , soon the populations would have merged

I would say that our immune system was better than theirs. While we may have killed some off, it is more likely that we could adapt to viruses and bacteria that they could not, which made us carriers of their extinction.

I think you should specify that the concept of "better" is relative purely to the concept of survival or we risk to end up in a minefield.
