The single fossil site Dmanisi, Republic of Georgia, rivals numerous sites in Tanzania and East Africa not only in geological age, 1.85-
1.78 million years ago, but also and especially in morphological diversity of human fossils. Recent research has demonstrated that although brief, the geological history of the site was not, as might be expected, relatively uniform, but rather very complex. This interesting and unique situation impacts interpretation of the human remains and, more broadly, raises important questions about the interpretation of human evolution during this period.
