Even a site such as Bilzingsleben is not generally accepted as a base camp of early hominines. The claims and believes of Prof. Ziegert are not new. Until there is no solid publication available I recommend to remain very sceptic.

I agree indeed, if this theory is confirmed by subsequent publications it will indeed be quite a change in the understanding of the evolution of human settlements.
However, I find journalists statements like " Our earliest ancestors gave up hunter-gathering and took to a settled life up to 400,000 years earlier than previously thought, according to controversial research." detrimental to a proper understanding of such information.
It would be more correct in my opinion to use statements like "Some Homo Erectus managed to organise settlements as far ago as 400K years". This in itself is challenging enough previous theories. There is no need to generalise to all Homo Erectus this settlement capability.
Note that this is a common practice among journalists and even some palaeoantropologists. We often read statements like "Homo Erectus was able to do this and that, but not those other things.", Like wise Neanderthals had developed such and such hunting methods. This is a gross misrepresentation of the probable reality which was most likely made out of a broad diversity of subgroups with various modes of adaptation to their environments, like it is still the case nowadays.
