Stone Age artists were painting red disks, handprints, clublike symbols and geometric patterns on European cave walls long before previously thought, in some cases more than 40,000 years ago, scientists reported on Thursday, after completing more reliable dating tests that raised a possibility that Neanderthals were the artists.
Genetic dates are based on a mixture of statistics and best guesses, but the split times calculated by the Danish team are compatible with the more reliable archaeological dates, which record the earliest known human presence in Australia at 44,000 years ago.
More reliable paleomagnetic dating, limited to rocks dating from after Kīlauea's emergence from the sea, has suggested ages of around 50,000 years.
It was years in the making — the result of a complex algorithm for pairing gorillas that may be more reliable than dating Web sites for humans.

Including regular sound changes yielded an approximately 4-fold improvement in the characterization of linguistic change over a simpler model of sporadic change, improved phylogenetic inference, and returned more reliable and plausible dates for events on the phylogenies.
The ultrasonographic measurements of the fetal BPD is a more reliable method, predicting date of spontaneous delivery with greater certainty than even a certain LMP [ 4- 7].
The research is "most important," Dr. Delson said, because it introduces a significant advance in techniques for more reliable, precise and older dating of antiquities, especially cave art that in most cases does not lend itself to reliable dating by radiocarbon methods.
Scientists using a "more reliable" form of radiocarbon dating have re-assessed fossils from the region and found them to be far older than anyone thought.
