Australopithecus afarensis (Lucy) is widely cited as a pivotal fossil specimen illustrating a transitional form in the hominin lineage, representing an evolutionary link between ancestral apes and humans. Despite popular belief, the evidence we have shows Lucy is simply an extinct ape whose significance has been exaggerated to fit an evolutionary narrative.

The critique centers on the following points:

The Flaw in the Narrative

• Ideology Over Data: Much paleoanthropology is "data poor, imagination rich" and its theories are driven more by an ideology—the need to establish an ape ancestry for man—than by the evidence itself.
• The "Ape-Man" Fabrication: The supposed "ape-men" examples are created in three ways: upscaling apes (exaggerating human-like features), downscaling humans (minimizing human features), or fabricating a creature by combining separate ape and human bones (like the Piltdown Man hoax).

Critique of Lucy's Anatomy

Models of Lucy are misrepresentations that ignore her ape-like features:

• Tree-Dwelling Adaptations: Unlike human-like models in museums (like the one at the St. Louis Zoo), the actual fossil evidence from Lucy's species shows highly curved finger and toe bones (phalanges) and locking wrist bones. These features are strong indicators of a suspensory adapted (hanging) and knuckle-walking primate, not an efficient ground walker.
• The Knee Angle: While Lucy has a "carrying angle" in her knee (femurs converge inward) that is shared with humans, this is not proof of evolution. Other modern, non-human primates (like the orangutan and spider monkey) also possess this angle, likely as an adaptation for walking on narrow tree limbs.
• The Pelvis (Hip Bones): Lucy's iliac blades flare laterally (out to the side), a feature of apes, which is poorly suited for the human walking gait. Previously an anthropologist had to physically cut and reshape a plaster copy of Lucy's crushed pelvis to make it appear human-like and thus consistent with upright walking.

The Laetoli Footprints Conflict

The 3.7-million-year-old Laetoli footprints are described as being the crucial piece of evidence that the evolutionary community attempts to force onto Lucy.

• Footprints are Human: The footprints are "indistinguishable" from those of a habitually unshod modern human, showing a clear arch, a straight (non-grasping) big toe, and the distinctive left-right heel-to-toe stride.
• Circular Reasoning: The footprints are used to prove Lucy walked upright, but Lucy's existence is used to date the prints to a time before humans are supposed to have existed. The attribution is based solely on the preconception that no humans were "around three million years ago."

Conclusion on Morality

The debate over origins is fundamentally a moral one: if man descended from Adam (Creation), our morals are absolute; if we descended from an ape (Evolution), morality is relative.
