Creationists refuse to recognise early hominins such as the australopithecines because they stubbornly refuse to conform to the creationist dogma that says there are no fossils showing the transition from a common ancestor with chimpanzees. Therefore, in the arrogant way creationists often deal with reality, because their stated dogma says otherwise, these fossils can't exist, and ad hoc explanations for their existence have to be invented — the dates are wrong; the scientists lied; Satan planted them to mislead us, etc., etc.

However, they do exist, and now scientists at the Centre national de recherche scientifique (CNRS), France, have succeeded in reconstructing the face of the australopithecine known as 'Little Foot', which was badly crushed and fragmented by the pressure and movement of the sediment in which it was buried. 'Little Foot', discovered at Sterkfontein, South Africa, is the most intact skeleton of an Australopithecus so far found, and this reconstruction helps place it in the evolutionary tree of the hominins as they diverged from the other African great apes. Their findings are published, open access, in the journal Comptes Rendus Palevol.

This reconstruction reveals a number of transitional features, just as one would expect of an early hominin roughly halfway in time between the split from the common ancestor with chimpanzees some 6 million years ago and the emergence of anatomically modern humans. But it also raises an intriguing question, because it appears to be closer to the East African australopithecines than to the South African australopithecines, raising questions about the evolutionary relationship between these two groups and the chronology of the evolution of the modern human face.

'Little Foot' was originally assigned to the species Australopithecus prometheus and later to Au. africanus, but is a school of thought that argues it is sufficiently different to other Australopiths to justify assigning it to a new species altogether.

Australopithecus and the Sterkfontein Fossils. Australopithecus – Early Human Ancestors

The genus Australopithecus includes several species of early hominins that lived in Africa roughly 4.2 to 2 million years ago. These species are widely regarded as close relatives of the ancestors of modern humans and represent important transitional forms between the last common ancestor shared with chimpanzees and the later genus Homo.

Australopithecines show a mixture of ape-like and human-like features. Their brains were relatively small (around 400–500 cm³, comparable to chimpanzees), but their pelvis, legs, and feet indicate habitual upright walking. At the same time, their long arms and curved fingers suggest they still spent considerable time climbing in trees.

The Sterkfontein Caves

The famous fossil site where “Little Foot” was discovered lies at Sterkfontein, part of the Cradle of Humankind World Heritage Site in South Africa. The caves contain deposits spanning several million years and have produced one of the richest collections of early hominin fossils ever found.

These fossils accumulated in cave systems where sediments, rockfalls, and mineral deposits gradually buried the remains of animals and hominins that had fallen into natural openings.

“Little Foot”

“Little Foot” is the nickname given to an exceptionally complete australopithecine skeleton discovered in the Sterkfontein caves by palaeoanthropologist Ronald Clarke in the 1990s. The specimen is thought to be around 3.6–3.7 million years old.

Unlike most early hominin fossils—which are often just fragments—Little Foot preserves almost the entire skeleton, making it one of the most informative specimens for understanding early hominin anatomy.

Key features include:

Long arms and curved fingers suggesting climbing ability
A pelvis and leg bones adapted for upright walking
Feet showing a human-like big toe alignment, unlike the grasping feet of chimpanzees

Because of its completeness, the specimen provides rare insights into how early hominins combined arboreal and terrestrial lifestyles.

The work of the CNRS team is reported in a CNRS press release.

The first digital reconstruction of the face of « Little Foot »
Identified as the most complete Australopithecus fossil discovered to date¹, “Little Foot” was buried in sediments whose movement and weight caused fractures and deformations, making analysis of its skull—and more particularly its face—difficult. This anatomical region, which is essential for understanding the adaptations of our ancestors and relatives to their environment, has now been virtually reconstructed for the first time by a CNRS researcher² and her British and South African colleagues. These results will be published in the open-access journal Comptes Rendus Palevol on March 2.
A comparative analysis of this reconstruction with several extant great apes and three other Australopithecus specimens reveals that the face of “Little Foot” is closer in terms of size and morphology to Australopithecus specimens from eastern Africa than to those from southern Africa. This finding raises questions about the relationships between these different populations and about the chronology of the evolutionary processes that reshaped the faces of these hominins³ , particularly the orbital region, which appears to have been subject to strong selective pressures. The skull was first transported to the Diamond Light Source synchrotron (United Kingdom), where it was carefully digitised. The research team then virtually isolated the bone fragments using semi-automated methods and supercomputers. Their realignment resulted in a 3D reconstruction with a resolution of 21 microns. More than five years were required to complete this reconstruction. Publicly available in open access as of March 2, it will allow the international scientific community to consolidate the established model and to study other areas of the “Little Foot” skull in greater detail, particularly the braincase.

ABSTRACT
Besides being taxonomically and phylogenetically informative, changes in the size and shape of the hominin face through time can reflect important functional adaptations. Recent discoveries of well-preserved Australopithecus crania, particularly StW 573 (“Little Foot”) from Sterkfontein, South Africa, have enriched the fossil record. Although nearly complete, the StW 573 skull has suffered post-depositional damage, leading to the displacement and fragmentation of its facial structures. This study presents a preliminary digital reconstruction and comparative analyses of the StW 573 face. The skull was scanned at the Diamond Light Source (United Kingdom), and semi-automated segmentation was used to digitally separate bones and teeth from the surrounding matrix, and isolate bone fragments. The fragments were then digitally reassembled through visual alignment. The reconstructed StW 573 face was compared to those of Gorilla, Homo, Pan, and Pongo, and to the Australopithecus specimens Sts 5 (Australopithecus africanus from South Africa, 3.4-3.5 Ma) and A.L. 444-2 (Australopithecus afarensis from Ethiopia, 3.8 Ma), using standard linear measurements and a landmark-based geometric morphometric (GM) approach. The dimensions of the StW 573 reconstructed face, as assessed by the linear measurements, fall within the ranges observed in Gorilla and Pongo. Our GM analysis reveals that the shape of the reconstructed face of StW 573 is more similar to A.L. 444-2 than to Sts 5, with both fossils plotting close to extant Pan and Pongo groups in shape space. In addition to documenting close similarities between StW 573 and the eastern African Australopithecus specimen A.L. 444-2, our results provide new insights into the variability of the Australopithecus facial skeleton and raise questions on the adaptations and evolutionary polarity (e.g. ancestral pattern shared between eastern and southern African Pliocene Australopithecus) underlying changes affecting the orbital region within the genus.

What this reconstruction of “Little Foot” demonstrates once again is how steadily the fossil record continues to fill in the details of human evolution. Each new discovery adds another piece to the picture, revealing the gradual accumulation of anatomical changes that eventually produced modern humans. Far from the caricature promoted by creationists, the evidence shows a branching evolutionary history populated by species with mixtures of ancestral and derived traits — exactly what evolutionary theory predicts.

Finds such as Little Foot are particularly important because they show that the transition from ape-like ancestors to modern humans did not happen in a single sudden leap. Instead, it unfolded over millions of years through populations that retained some primitive characteristics while acquiring new adaptations such as habitual bipedalism, changes in facial structure, and eventually larger brains. The combination of features revealed by this reconstruction illustrates that evolutionary transition perfectly.

And, of course, every such discovery further exposes the emptiness of the creationist claim that there are “no transitional fossils”. The australopithecines — including Little Foot — are precisely the kind of intermediate forms that creationists insist do not exist. Yet they continue to be discovered, studied and reconstructed with ever greater precision.

In reality, the growing body of fossil evidence from sites such as Sterkfontein shows that humans did not appear suddenly and fully formed, but emerged from a long evolutionary history shared with the other African apes. Each new discovery simply reinforces what modern biology, genetics and palaeontology have already made abundantly clear: the human lineage is part of the evolutionary tapestry of life on Earth.
