Keels occur in some species like H. erectus, and occasionally in H. heidelbergensis, but are very rare in modern humans, probably due to the trend of overall thinning of cranial bones.The cranial bones are thicker than those of modern humans, and some Homo erectus skulls have a slight thickening along the sagittal suture called a sagittal keel. Large, shelf-like brow ridges hang over the eyes. The face is less prognathic, and the back teeth are smaller than those of Homo habilis.
