Which group of skulls is noted for showing the greatest similarity to Homo sapiens?

The group of skulls that shows the greatest similarity to Homo sapiens is Neanderthals. Neanderthals are often considered to be the closest relatives to modern humans, sharing a common ancestor and exhibiting a range of anatomical features that are notably similar to those found in Homo sapiens. For instance, while Neanderthals had some distinct characteristics such as a robust build and specific cranial features, overall, their skull structure—including certain aspects of the forehead, brow ridge, and dental arrangement—align more closely with that of modern humans compared to other hominin groups.

In contrast, Australopithecines display significant differences in skull shape and size that reflect their earlier evolutionary status, leading to a more ape-like appearance. Homo habilis, being one of the first members of the genus Homo, presents a more primitive form with pronounced features that diverge more from modern human anatomy. Early Homo erectus shows advancements over earlier hominins but still retains several traits that make it distinct from Homo sapiens. Thus, when comparing these various groups, Neanderthals stand out for their closer evolutionary link and similarity to contemporary humans.
