Dating earliest life
Article Abstract:
Geologists are attempting to search the oldest-known sedimentary rocks on Earth for traces of primitive life, either in the form of cellular microfossils, or as chemical and isotropic tracers characteristic of biological processes. Although a small outcrop of supposedly sedimentary rocks, claimed to be more than 3.85 billion years old, are examined for the purpose, on a tiny island of Akilia, Greenland, geologists cannot substantiate claims for presence of graphite in any of the crucial Akilia apatite grains.

Surprisingly rapid growth in neanderthals
Article Abstract:
The astonishingly rapid growth in neanderthals is examined by testing the dental growth. This autapomorphy in growth is a revolutionary reversal, and points strongly to a specific distinction between H. sapiens and H. neanderthals.
