New Human Fossils found

From the articles it looks like they found more fossils matching KNM-ER-1470.Interesting that there were three different types of Homo around at the same time.Wish they would find those fossils quicker! This is getting interesting.

One of the tools they are now using is multivariate statistics.Discriminant function analysis is quite useful for determining whether new specimens are similar to or different from a particular body of data.

One method of using multivariate statistics would involve measuring the teeth of all known fossil specimens in these various species, going back to the apes. Discriminant analysis would then be able to organize those teeth into groups according to their overall similarities.Here is a link to an article that used this type of statistics for a related purpose:Patterns of dental development in Homo, Australopithecus, Pan, and Gorilla - PubMed

To make things more interesting, a new study is out:

We still have a lot to learn!

You are correct, that particular study doesn't deal with these most recent finds.I posted it to try to illustrate one of the methods used.
