Further evidence comes from the complete agreement between radiometric dates and other dating methods such as counting tree rings or glacier ice core layers.Homo rhodesiensis "Broken Hill Cranium": dated to either 130,000 years ago (using amino acid racemization determination) or 800,000 to 600,000 years ago (within the same time as Homo erectus), depending on which dating method is used.This category is contrasted with anatomically modern humans, which include the subspecies Homo sapiens sapiens and Homo sapiens idaltu.Please note that any compilation of Stone Age art is bound to be both selective and subject to revision as new archeological discoveries are made.Furthermore, despite the widening range of archeological dating techniques - such as radiometric carbon dating, Uranium/Thorium and thermo-luminescence dating - not every work of art can be dated with great accuracy if the geological environment lacks important measurable elements.Thus sometimes, dating is dependent on paleontologist scholarship to provide the historical context against which an artifact's relevance and age can be assessed, through stylistic comparison with cave paintings and engravings at other archeological sites.

At present, a large variety of fossils, tools and artifacts are being studied by paleoanthropologists and other Stone Age scholars, in order to fix their date of origin.

Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.

Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.

Modern humans are theorized to have evolved from archaic humans, who in turn evolved from Homo erectus.
