These new data point to diversity of patterns of facial growth in fossil Homo. KNM-WT 15000 is similar to Australopithecus and the extant African apes in this localized area of bone deposition. This pattern contrasts with that seen in KNM-WT 15000 where evidence of bone deposition, not resorption, was identified.

antecessor, and on the 1.5 My cranium KNM-WT 15000, part of an associated skeleton assigned to African H.
We mapped the distribution of facial growth remodeling activities on the 900–800 ky maxilla ATD6-69 assigned to H. For humans, surface resorption commonly dominates on anteriorly-facing areas of the subnasal region of the maxilla and mandible during development. This change in facial profile is associated with a characteristic spatial distribution of bone deposition and resorption: growth remodeling. The modern human face differs from that of our early ancestors in that the facial profile is relatively retracted (orthognathic).
