A Homo erectus hyoid bone: possible implications for the origin of the human capability for speech

Unlike the hyoid of the Neanderthal from Kebara, this one is not a fully human and functional one. B U T, it is also certainly not an ape hyoid. I'll cite the abstract of the paper a few times:
The hyoid bone body shows the bar-shaped morphology characteristic of Homo, in contrast to the bulla-shaped body morphology of African apes and Australopithecus.
Creationist conclusion, Homo erectus was human.
The almost total absence of muscular impressions on the body's ventral surface suggests a reduced capability for elevating this hyoid bone and modulating the length of the vocal tract in Homo erectus.
Creationist conclusion, this Homo erectus or Homo erectus in general, had a handicap.
The shield-shaped body, the probable small size of the greater horns and the radiographic image appear to be archaic characteristics; they reveal some similarities to non-humans and pre-human genera, suggesting that the morphological basis for human speech didn't arise in Homo erectus.
Conclusion of this Creationist: Stalin had a pre-Flood, more successful predecessor.

So, Stalin failed, thank God. Someone in pre-Flood times seems to have asked demons to use CRISPR to insert ape genes to create supersoldiers, and a side effect was the speech handicap. Orc breeding. Or, this is what happened naturally, when fallen angels tried to do what human fathers do, as a punishment.
Either way, such things would have been one of the things contributing to violence and injustice on earth, and one of the reasons for the Flood of Noah.

PS, the Hyoid bones in Sima de Huesos were human:

The Atapuerca SH hyoids are humanlike in both their morphology and dimensions, and they clearly differ from the hyoid bones of chimpanzees and Australopithecus afarensis. Their comparison with the Neandertal specimens Kebara 2 and SDR-034 makes it possible to begin to approach the question of temporal variation and sexual dimorphism in this bone in fossil humans. The results presented here show that the degree of metric and anatomical variation in the fossil sample was similar in magnitude and kind to living humans.
