Dr. John Harris, of Rutgers University and one of the authors of the study, stated, “The Ileret footprints add to evidence that early Homo erectus had a body adapted to traveling long distances, at a time when food sources were patchily distributed across the landscape.” [Science News: “Modern feet step back 1.5 million years]
However, the Science News article states that a controversy still exists as to whether these footprints are from Homo erectus or Homo ergaster, or an earlier ancestor that had a more ape/human-like appearance as that found in unearthed evidence from the species Australopithecus afarensis.
Please read the Science News article for more information on this scientific discussion.
