According to experimental studies in Europe, these handprints were created by spreading fingers apart and blowing paint from the mouth through a tube over the hands and fingers and onto the rock surface.

During archaeological works on Sulawesi, researchers collected and dated 19 samples taken from 12 handprints and 2 animal images from 7 caves near the town of Maros (South Sulawesi).

Fixing that issue -- often nothing more than weak back and core muscles -- is critical.

Their new technique involved first polishing a slice of bone and then shooting a laser beam onto its surface.But radiodating cannot proceed without some primary assumptions: the starting conditions of a given sample (e.g., how much of each isotope was present in the beginning), a steady rate of decay of certain radioactive isotopes of elements called radioisotopes, and a lack of tampering with the system (e.g., elements added or subtracted since the radioisotope "clock" first began counting time).Then, the current amount of radioisotope is compared to the amount of stable element into which it is slowly changing. However, evidence has mounted that radioisotopes underwent a period of radical acceleration of decay in the past.This evidence has indicated that radioisotopes have not decayed at a constant rate, and therefore the radiodating "clocks" in general are all broken.Advances in direct radiocarbon dating of Neanderthal and anatomically modern human (AMH) fossils and the development of archaeostratigraphic chronologies now allow refined regional models for Neanderthal–AMH coexistence.
