Preserved in post-Flood sediments older than any Neanderthals and Hobbits are Homo erectus fossils.3 Aside from the skull, Homo erectus skeletons are virtually indistinguishable from modern humans, so the evidence indicates they are human.

From an "evolutionist" point of view, we see Wise attempting to squeeze hundreds of thousands of years of our evolutionary history, from erectus to sapiens, into a few hundred years
It doesn't appear to me that Wise is attempting anything on the subject of hominids. He says quite clearly that Homo erectus skeletons are virtually indistinguishable from modern humans meaning that they are our human ancestors, not our apeman evolutionary relatives.
If humans scattered from a central postion and became isolated populations, they would have had subsets of the original genetic variation and thus would have had anatomical differences though they would have been entirely human nonetheless.
Kurt Wise, a YEC guru, is embracing them as our ancestors, and the implications are that Adam, Eve and Noah were all small brained Homo Erectus, the original "kind" from which Homo Sapiens, Neanderthal, and Homo Floresiensis all evolved.
Nonetheless and despite any localized population variations, they were all human, so they are our ancestors after all since all humans are related.
