A brief communication, published last November in the American Journal of Biological Anthropology may, if creationists never read past the title (as usual), have produced a frisson of excitement in those circles. It questioned the taxonomic status of one of the most complete fossil skeletons of an early ancestral hominin, Australopithecus prometheus, popularly known as “Little Foot”.
However, reading even a little further would have turned that excitement into disappointment — assuming, of course, that they understood what they were reading. The authors were not questioning whether the fossil was ancestral at all, but whether it had been assigned to the correct position in the hominin family tree, or whether it should instead be recognised as a distinct ancestral hominin species. In other words, this was a discussion about how many transitional species there are, not whether transitional species exist at all.
The only crumb of comfort available to creationists is the familiar claim that this demonstrates how science “keeps changing its mind”, something they take as evidence that science is fundamentally unreliable—presumably including even those parts they routinely misrepresent as supporting their beliefs.
For anyone who understands the scientific method, and the importance of treating all knowledge as provisional and contingent on the best available evidence, this paper represents the principle functioning exactly as it should. Far from being a weakness, this willingness to revise conclusions in the light of new information is what makes science self-correcting and progressively more accurate over time.
The authors of the paper — a team led by La Trobe University adjunct Dr Jesse Martin—carried out a new analysis of the “Little Foot” fossils and concluded that the specimen was probably placed in the wrong taxon when first described on the basis that it does not share the same “unique suite of primitive and derived features” as Australopithecus africanus. Since that initial assessment, additional fossils of A. prometheus have been discovered, and it has become clear that “Little Foot” also differs from those specimens. At the same time, it remains sufficiently distinct from A. africanus that reassignment to that species is not justified. In short, it possesses its own unique combination of primitive and derived traits and should therefore be recognised as a separate species.
Naturally, there is no real comfort here for creationists. The phrase “suite of primitive and derived features” is simply palaeontological shorthand for evidence of descent with modification—what Darwin referred to as transitional forms. It follows that the researchers involved have no doubt whatsoever that the species under discussion evolved from earlier ancestors, and there is no hint that they believe it was spontaneously created, without ancestry, by magic.
