Morphology and interpretations

Both H. antecessor and H. heidelbergensis are likely to be descended from the morphologically very similar Homo ergaster

from Africa. But because H. heidelbergensis had a larger brain-case — with a typical cranial volume of 1100–1400 cm³ overlapping the 1350 cm³ average of modern humans — and had more advanced tools and behavior, it has been given a separate species classification. The species was tall, 1.8 m (6 ft) on average, and more muscular than modern humans. Large males may have weighed around 100 kg (220 lb). According to Professor Lee R. Berger of the University of Witwatersrand, numerous fossil bones indicate some populations of Heidelbergensis were "giants" routinely over 2.13 m (7 ft) tall and inhabited South Africa between 0.5 million and 300,000 years ago.

Some experts believe that H. heidelbergensis, like its descendant H. neanderthalensis, acquired a primitive form of language. No forms of art or sophisticated artifacts other than stone tools have been uncovered, although red ochre, a mineral that can be used to create a red pigment which is useful as a paint, has been found at Terra Amata

or H. heidelbergensis. Generally, projectile weapons are more commonly associated with H. sapiens. The lack of projectile weaponry is an indication of different sustenance methods, rather than inferior technology or abilities. The situation is identical to that of native New Zealand Māori, modern H. sapiens, who also rarely threw objects, but used spears and clubs instead.

Divergent evolution

Because of the radiation of H. heidelbergensis out of Africa and into Europe, the two populations were mostly isolated during the Wolstonian Stage and Ipswichian Stage, the last of the prolonged Quaternary

s. Neanderthals diverged from H. heidelbergensis probably some 300,000 years ago in Europe, during the Wolstonian Stage; H. sapiens probably diverged between 200,000 and 100,000 years ago in Africa. Such fossils as the Atapuerca skull and the Kabwe skull bear witness to the two branches of the H. heidelbergensis tree.

Homo neanderthalensis retained most of the features of H. heidelbergensis after its divergent evolution. Though shorter, Neanderthals were more robust, had large brow-ridges, a slightly protruding face and lack of prominent chin. With the possible exception of Cro-Magnon Man, they also had a larger brain than all other hominins. Homo sapiens, on the other hand, have the smallest brows of any known hominin, are tall and lanky, and have a flat face with a protruding chin. H. sapiens have a larger brain than H. heidelbergensis, and a smaller brain than H. neanderthalensis, on average. To date, H. sapiens is the only known hominin with a high forehead, flat face, and thin, flat brows.

Some believe that H. heidelbergensis is a distinct species, and some that it is a cladistic ancestor to other Homo forms sometimes improperly linked to distinct species in terms of populational genetics.

Some scenarios of survival include
  • H. heidelbergensis > H. neanderthalensis
  • H. heidelbergensis > H. rhodesiensis
