Remains of new human species found

[Anomalocaris]

According to CNN they apparently buried their dead.

That might suggest they had some conception of life after death. Previously no hint of such conceptual ability have been found amongst any creature with a brain smaller than that of homosapien. This creature has the brain the size of a chimp.

But, from what I read, the dead were shoved through a crack into a cave chamber. There were no word of evidence that efforts were made to make the dead comfortable. So IMHO the circumstances of these remains are not quite the equivalent of a burial with grave goods, so it is not conclusive this was a true burial that demand a conception of afterlife.
