Often times we take the word "species" for granted; that it is somehow easy to place animals into certain categories and never look back. But this article entitled Christening the Earliest Members of Our Genus, recently published in the New York Times reminds us just how difficult it is to categorize different animals -- even the earliest members of our own genus! While our earliest ancestors, clustered in Africa with an ape-like fossil structure, the fossils of hominids from 1.5-1.8 million years ago were different from those earliest ancestors. What's more, their geography changed too! Newer fossils were found not only in Africa, but across Asia as well! But what species did these newer fossils belong to? This article indicates that this question is not so easily answered because it seems 5 "gorgeously preserved" 1.8 million year old skulls from ONE site in Dmanisi (Republic of Georgia) all had slightly different characteristics! And yet G. Philip Rightmire of Harvard University, indicated that, "They don't represent distinct species. They're just one group." Another biological anthropologist from New York University, Todd R. Disotell, indicates a similar issue in categorizing baboons ... "What we need, practically, is labels for them. We will never solve the species problem for fossils if we can't for living, breathing animals." It's interesting to remember how scientific labeling is, in fact, quite fluid and ever-evolving; constantly being adapted and refined as we use geography, archaeology, anthropology to keep learning more about animals, both those long-deceased and those living in the present-day.
