THE EVOLUTION OF EARLY HOMO: A REPLY TO SCOTT

Scott presents a welcome reply to our article, “A single lineage in early Pleistocene Homo” (Van Arsdale and Wolpoff 2012 ). However, Scott's reply mischaracterizes and fails to directly address the hypothesis of a single lineage that we test. Additionally, the approach taken by Scott fails to replicate the methods used in our analysis. As Scott himself suggests, our null hypothesis of a single evolving lineage in early Homo remains without refutation. Although many evolutionary scenarios might explain the complex pattern of variation present in the early Homo fossil record, the most parsimonious remains that of a single lineage displaying evolutionary change over time.
