The interdiction has been lifted for the article, 'Neandertal Demise: An Archaeological Analysis of the Modern Human Superiority Complex.'.

In this study, scientists systematically tested the strength of some of the archaeologically derived explanations for Neandertal extinction, such as the Neandertals' supposed lack of complex language, inferior capacity for innovation, inferior hunting ability, and smaller social networks, as well as other environmental explanations, including harsh climate or volcanic eruptions that occurred at the time of their decline.
If the Neandertal record is compared to that of African Middle Stone Age human contemporaries, instead of the modern humans that succeeded them, the differences between them and humans in their capacities, like weaponry, subsistence, and use of symbols are too small to explain their demise in terms of cognitive or behavioral inferiority. Instead, the authors argue, genetic data recently obtained from Neandertal skeletal remains suggest that complex and drawn-out processes of interbreeding and assimilation may have been responsible for the disappearance of the specific Neandertal morphology from the fossil record.
