The great similarity between the skeletal and cranial structures of australopithecines and chimpanzees, and the refutation of the claim that these creatures walked upright, have caused great difficulty for evolutionary paleoanthropologists. The reason is that, according to the imaginary evolution scheme, Homo erectus comes after Australopithecus. As the genus name Homo (meaning "man") implies, Homo erectus is a human species, and its skeleton is straight. Its cranial capacity is twice as large as that of Australopithecus. A direct transition from Australopithecus, which is a chimpanzee-like ape, to Homo erectus, which has a skeleton no different from modern man's, is out of the question, even according to evolutionist theory. Therefore, "links"- that is, transitional forms-are needed. The concept of Homo habilis arose from this necessity.

Femur KNM-ER 1472. This femur is no different from that of modern man. The finding of this fossil in the same layer as Homo habilis fossils, although a few kilometers away, gave rise to incorrect opinions, such as that Homo habilis was bipedal. Fossil OH 62, found in 1987, showed that Homo habilis was not bipedal, as had been believed. Many scientists today accept that Homo habilis was a species of ape very similar to Australopithecus.

The classification of Homo habilis was put forward in the 1960s by the Leakeys, a family of "fossil hunters." According to the Leakeys, this new species, which they classified as Homo habilis, had a relatively large cranial capacity, the ability to walk upright and to use stone and wooden tools. Therefore, it could have been the ancestor of man.

New fossils of the same species unearthed in the late 1980s were to completely change this view. Some researchers, such as Bernard Wood and C. Loring Brace, who relied on those newly-found fossils, stated that Homo habilis (which means "skillful man," that is, man capable of using tools), should be classified as Australopithecus habilis, or "skillful southern ape," because Homo habilis had a lot of characteristics in common with the austalopithecine apes. It had long arms, short legs and an ape-like skeletal structure just like Australopithecus. Its fingers and toes were suitable for climbing. Their jaw was very similar to that of today's apes. Their 600 cc average cranial capacity is also an indication of the fact that they were apes. In short, Homo habilis, which was presented as a different species by some evolutionists, was in reality an ape species just like all the other Australopithecines.

Research carried out in the years since Wood and Brace's work has demonstrated that Homo habilis was indeed no different from Australopithecus. The skull and skeletal fossil OH62 found by Tim White showed that this species had a small cranial capacity, as well as long arms and short legs, which enabled them to climb trees just like modern apes do.

The detailed analyses conducted by American anthropologist Holly Smith in 1994 indicated that Homo habilis was not Homo, in other words, human, at all, but rather unequivocally an ape. Speaking of the analyses she made on the teeth of Australopithecus, Homo habilis, Homo erectus and Homo neanderthalensis, Smith stated the following;

Restricting analysis of fossils to specimens satisfying these criteria, patterns of dental development of gracile australopithecines and Homo Habilis remain classified with African apes. Those of Homo erectus and Neanderthals are classified with humans.189

Within the same year, Fred Spoor, Bernard Wood and Frans Zonneveld, all specialists on anatomy, reached a similar conclusion through a totally different method. This method was based on the comparative analysis of the semicircular canals in the inner ear of humans and apes, which allow them to maintain their balance. Spoor, Wood and Zonneveld concluded that:

Among the fossil hominids the earliest species to demonstrate the modern human morphology is Homo erectus. In contrast, the semi-circular canal dimensions in crania from southern Africa attributed to Australopithecus and Paranthropus resemble those of the extant great apes.190

Spoor, Wood and Zonneveld also studied a Homo habilis specimen, namely Stw 53, and found out that "Stw 53 relied less on bipedal behavior than the australopithecines." This meant that the H. habilis specimen was even more ape-like than the Australopithecus species. Thus they concluded that "Stw 53 represents an unlikely intermediate between the morphologies seen in the australopithecines and H. erectus."191

This finding yielded two important results:

1. Fossils referred to as Homo habilis did not actually belong to the genus Homo, i.e., humans, but to that of Australopithecus, i.e., apes.

2. Both Homo habilis and Australopithecus were creatures that walked stooped forward-that is to say, they had the skeleton of an ape. They have no relation whatsoever to man.

The claim that Australopithecus and Homo habilis walked upright was disproved by inner ear analyses carried out by Fred Spoor. He and his team compared the centers of balances in the inner ears, and showed that both moved in a similar way to apes of our own time.
