Assumption 401: Long-term effects from inbreeding are only expected from a physiological and genetic base. Therefore, inbreeding cultures must be based on an enduring instinct. We further assume dilution of the inbreeding instinct by mixing with outbreeding cultures.

Assumption 397: Inbreeding has genetic properties in the first place, from which culture is just a consequence. Inbreeding must be seen as a bipedal primate religious instinct. The problem from Western society is to see Muslim inbreeding as an existential choice rather than a natural lust leading to perpetual orgasm.

Assumption 398Homo naledi theoretically can have been an extremely inbred population without much contact with modern hominins. But still, they can have developed human characteristics by convergent evolution.



Why Homo naledi had an inbreeding culture

Homo naledi had an inbreeding culture what is clear from how they treated their dead in Dinaledi Chamber. In my opinion they believed in 'rebirth without soul', what means that ancestors cannot choose the womb of rebirth:


Assumption 383:
Muslim males think it is their own choice to reincarnate into their tribe or family, into their inbred descendants created by cousin marriages. This, because Muslims believe in the soul. But Homo naledi was wiser and wondered if ancestors really would return to their tribe, or that they could be reborn anywhere. Maybe hybrids from Homo erectus would start a new life in the Homo naledi tribe. That would be disastrous, for Homo naledi males hated the handsome Homo erectus males because of sexual competition around naledi females.

Assumption 386: The difference between rebirth and reincarnation is that in rebirth the own body of flesh and blood revives.



Believing in the soul means that the body is not that important and that the grave is closed with a stone, through which the soul can escape into another person.
So the crucial difference is if the grave is open or closed. Not always as with Jesus, who - by the way - had a soul while reborn.



The burial of Dinaledi Chamber was open. Not the soul but the body had to be able to leave the cave. Also, Naledi Chamber and Lesedi Chamber had the entrance as exit. So, Homo naledi knew where reborn left the cave for conception. With the exit under control they prevented their ancestors from getting lost and reborn into Homo erectus tribes:


Assumption 382: Rebirth without soul.
All life comes from the soil, all plants, all fruits come from the ground. 




So, also human life must enter the womb of women through the soil. Well, of course, Australopiths knew about sexual cause and effect, but did not understand how everything came to growth and to life. They concluded, it must be the Underworld which is life giving. Bipedal primates saw this happening every day. And deep in the ground - in the Underworld - lived their God of Darkness, the guardian of all life. It is Him who puts the reborn into the womb of women. That's why Homo naledi sought the deepest places for 'rebirth without soul'.



Homo naledi created a completely controlled rebirth room for ancestors in Dinaledi Chamber. He did not believe in the soul and reborn ancestors were guided to the only exit of the cave, where the wombs of Homo naledi females were waiting for conception:




Assumption 384Homo naledi rejected the soul as a joke, only to get a grip on the afterlife after death. Now, it is possible that Homo erectus (2.12 Ma; 900cc) evolved to 'reincarnation with the soul' already two million years ago, while Homo naledi continued to believe in 'rebirth without soul' until 335 ka ago. Since, today, there are still a lot of people not believing in the soul. 



Homo erectus believed in 'reincarnation with the soul'. Then, ancestors can determine where to be reborn. And if such Homo erectus tribe was also an outbreeding culture, it would not be bothered at all about reborn hybrids from other tribes.

Assumption 390Homo naledi's faith was based on inbreeding, because he enforced ancestors to be reborn into Homo naledi wombs. The religion of Homo erectus probably was based on outbreeding, because he chased the females from Homo naledi. (Circular reasoning).



The other reason that Homo naledi probably was an inbreeding culture is that they did not mix effectively with other hominin subspecies for two million years. Corresponding characteristics with modern humans may be caused by convergent evolution:

Assumption 398Homo naledi theoretically can have been an extremely inbred population without much contact with modern hominins. But still, they can have developed human characteristics by convergent evolution.

Homo Floresiensis had no contact with other hominins either, but was geographically isolated and unable to mix with other hominins:



But Homo naledi had plenty of choice to crossbreeding. Without oubreeding cultures the human race would still be half-Australopithecus.

Assumption 391Homo Floresiensis did not interbred with other hominin species for millions of years because he was geographically isolated. But Homo naledi remained partly Australopithecus out of free will and was not hindered by geographical barriers. This behavior can only be explained by his inbreeding culture.


Assumption 396: Inbred populations are not equal to outbred populations. Inbred populations are missing some characteristics by defective evolution, by insufficient crossing with other populations. Only reasonably mixed outbred populations are directly comparable. This implies no a priori moral judgment. All humans can be morally equivalent, in principle.

Long-term effects from inbreeding are only expected from a physiological and genetic base. Therefore, inbreeding cultures must be based on an enduring instinct.  We further assume dilution of the inbreeding instinct by mixing with outbreeding cultures.

Assumption 392Homo naledi survived for millions of years in an inbreeding culture, apparently sustained by a varied genome. It is proven they were all alike, and probably without autosomal recessive disorders.

The inbreeding instinct has genetic properties in the first place, from which culture is just a consequence. The problem in Western society is to see Muslim inbreeding as an existential choice in stead of a naturally lust.

Assumption 397: Inbreeding has genetic properties in the first place, from which culture is just a consequence. Inbreeding must be seen as a bipedal primate religious instinct. The problem from Western society is to see Muslim inbreeding as an existential choice rather than a natural lust leading to perpetual orgasm.

Assumption 338The inbreeding instinct is no joke, since we also have the outcrossing instinct as primal sexual law of nature. So, if Muslims want to compete outbreeding, they should replace it with the stronger instinct of inbreeding.

Assumption 193: The primal law of animal religion is the commandment: thou shalt reproduce in genetic diversity.


Assumption 336The inbreeding instinct is a human instinct developed somewhere between Homo erectus (2 Ma; 900cc) and the Arabian Peninsula (Homo sapiens, 60-50 ka; 1400cc). It is a typical male instinct which aims at earthly reincarnation into tribal inbred bodies enforced by cousin marriages. It is still vividly present in the Muslim culture. But there must have been an earlier inbreeding instinct aiming at 'rebirth without soul' in relation to Homo naledi.




Assumption 383:
Muslim males think it is their own choice to reincarnate into their tribe or family, into their inbred descendants created by cousin marriages. This, because Muslims believe in the soul. But Homo naledi was wiser and wondered if ancestors really would return to their tribe, or that they could be reborn anywhere. Maybe hybrids from Homo erectus would start a new life in the Homo naledi tribe. That would be disastrous, for Homo naledi males hated the handsome Homo erectus males because of sexual competition around naledi females.



Assumption 330: Haplo-groups N from L3N and M from L3M, both groups from mtDNA, are sibling-groups what means both might be connected with the inbreeding instinct in nuDNA.




Assumption 393Inbreeding was the primal religion of bipedal primates. Protection of tribal identity caused unwillingness to mix with other hominins and inbreeding became a stabilizer within the evolution tree. Inbreeding has slowed down and obstructed human evolution. On the other hand, outbreeding cultures have accelerated the evolution by combining randomly with whatever hominin on the road.








The mixing of species





Matching Homo erectus (reincarnation)
with Homo naledi (rebirth)

To understand the dangers threatening an inbreeding culture one must know the female outbreeding instinct which makes them looking for outstanding males from other tribes. Homo naledi females might have been interested in other bipedal hominins like 'handsome' Homo erectus, what could have triggered a panic reaction from Homo naledi males:



So, Homo naledi feared sexual encounters between handsome Homo erectus males and adulterous Homo naledi females. Well, we can estimate the extent to which their bodies would match. Homo naledi females were 140cm long and Homo erectus males varied from 170 - 180 cm:


Although the pelvis of Homo naledi females still had strong Australopithecine characteristics, the lower part of their bodies was not that ape-like and probably fitted Homo erectus' lower part reasonably:





Bipedal primate evolution never created an ape-like lower body with a human-like upper body:



Bipedality essentially developed the lower body, not the upper body. Hominin legs were developed by Australopithecus for long distance running in the first place. But it also became a sexual characteristic for all kinds of hominids and hominins later in the evolution.

It enabled the mixing of bipedal primate species in the twilight zone between hominids and hominins, starting about 2 million years ago. For the sexual intercourse between Homo erectus (as an actor), the upper body from Homo naledi females (as victims) was not that important. 

We do not suggest that forced sexual intercourse between Homo erectus and Homo naledi females had genetic influence on naledi's lower body. Simply, because we do not need that assumption, since we think Homo naledi had already longer legs in the evolution. 

On the other hand our scenario stretches over 100.000 years, from which several generations used Dinaledi Chamber as a burial. And a few encounters between Neanderthal males and Homo sapiens females already left traces in the human genome. So, the postulated fear from Homo naledi males about damage to their gene pool is not illogical. But as said, this assumption is not needed and we have no genetic indication.

Assumption 394:

1) Australopithecus probably developed hominin legs for long-distance running, from which evolved Homo erectus. Then, Homo naledi already had hominin legs from the beginning and did not change much from 2.3 Ma to 335 ka ago.

2) But because there is no standard evolution tree, retarded Homo naledi with ape-like legs might have got their hominin legs later in the evolution by mixing with Homo erectus. But Homo erectus might not have been sexually attracted to ape-like lower bodies. Also for other reasons this alternative is rejected.

3) The best hypothesis is that both Homo naledi and Homo erectus had already long legs around 335 ka ago and that Homo erectus was sexually attracted to Homo naledi females. Then our scenario could be successful, because then Homo naledi males had reason to protect their inbreeding culture against Homo erectus, who raped their females, and by preventing ancestors to be reborn into Homo erectus tribes.



For our scenario it is not important how Homo naledi and Homo erectus have developed earlier in the evolution. We are only interested in their hypothesized sexual relationship at 335 ka ago. We accept their morphology as facts from their skeletal remains.

But there are a number of modern hominin characteristics in Homo naledi, what even for an inbreeding culture is no wonder after two million years. Total inbreeding is impossible, so we can postulate some forced mingling with other species. 



Convergent evolution or homological structures


Convergent evolution - Wikipedia

    Convergent evolution is the independent evolution of similar features in species of different lineages. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups.The cladistic term for the same phenomenon is homoplasy

    Then, Homo naledi and Homo sapiens developed independently from each other similar features, which were not present in the last common ancestor, some Australopithecus. So, Australopiths can have developed human characteristics as well as Homo sapiens, without crossbreeding.



    homology is a character shared between species that was also present in their common ancestor. This can be contrasted with an homoplasy, which is a convergent character shared between species but not present in their common ancestor.




    So, belong modern human features exclusively to modern homo or they were in the pen of evolution? 

    With convergent evolution Homo naledi theoretically can have been a totally inbred population without any contact with Homo erectus. And striking differences with modern humans must be done by inbreeding:

    Assumption 398Homo naledi theoretically can have been an extreme inbred population without much contact with modern hominins. But still, they can have developed human characteristics by convergent evolution.



    Homo naledi evolution stagnated by inbreeding culture

    But then, the cardinal question is why the evolution of Homo naledi is stagnated for two million years? From 2.3 Ma to 236 ka. We expect further brain development but their brain remained small (550cc), and their Australopithecine body did not change much.

    So, the question is why did Homo naledi not evolve further? It is very simple: they did not mix with other tribes, other hominin species because of their extreme inbreeding religion:

    Assumption 391Homo Floresiensis did not interbred with other hominin species for millions of years because he was geographically isolated. But Homo naledi remained partly Australopithecus out of free will and was not hindered by geographical barriers. This behavior can only be explained by his inbreeding culture.


    Our Dinaledi scenario

    This is our scenario: A Homo erectus tribe settled in the neighbourhood of Homo naledi - 335 ka ago - and formed a threat for attractive Homo naledi females. This triggered an extreme reaction in the inbreeding culture from Homo naledi, who took far-reaching measures. They developed the Dinaledi protocol. 

    Assumption 395: The Dinaledi scenario:
    A Homo erectus tribe settled near the inbreeding culture of Homo naledi - 335 ka ago - and formed a threat for attractive Homo naledi females. This triggered an extreme reaction in which Homo naledi developed the Dinaledi protocol to preserve the species.



    Believing in the soul means that the body is not that important and that the grave is closed with a stone, through which the soul can escape into another person. So, the crucial difference is if the grave is open or closed. Not always as with Jesus, who - by the way - had a soul while reborn.

    The burial of Dinaledi Chamber was open. Not the soul but the body had to be able to leave the cave. Also, Naledi Chamber and Lesedi Chamber had the entrance as exit. So, Homo naledi knew where reborn left the cave for conception. With the exit under control they prevented their ancestors from getting lost and reborn into Homo erectus tribes:

    Assumption 399:
    Believing in the soul (reincarnation) means that the body is not that important and that the grave is closed with a stone, through which the soul can escape into another person. So, the crucial difference is whether the grave is open or closed. The burial chamber of Dinaledi Chamber was open. Not the soul but the body had to be able to leave the cave. Also, Naledi Chamber and Lesedi Chamber had the entrance as exit. So, Homo naledi knew where reborn left the cave for conception. With the exit under control they prevented their ancestors from getting lost and reborn into Homo erectus tribes.



    Assumption 402: Rebirth or reincarnation caves.
    In rebirth caves nothing was given to the dead. In the first place they never saw a baby newborn with a stone axe in his hand. Also, precious gifts would attract thieves, where the chambers were open and not protected. After all, reborn ancestors had to be able to leave the cave. So, rebirth and valuable gifts do not go together. Of course Homo naledi had stone tools, of course they had grass cables but they never left anything of value in the caves. Nobody was allowed to track their rebirth graves.

    Assumption 400The most brilliant contribution of Homo naledi to the evolution theory is that even if Homo erectus raped his females, the God of Darkness nevertheless would put Homo naledi ancestors into their wombs. The problem with this theory is that it can be checked and later on led to the downfall of Homo naledi as a culture.
