This seeming paradox is resolved by theoretical models suggesting that cultural evolution is exceedingly slow in its initial stages..In contrast, all humans (barring pathologies) can learn to speak, read, and write.

Humans have genetically based unique abilities making complex culture possible; an assemblage of traits which we term “cultural capacity”.

It is therefore proposed that a large study be undertaken to provide a calibration scale against which bones uncovered can be dated.

We investigated the radiocarbon ages and carbon and nitrogen isotope ratios of human skeletal remains from burials at the Yuigahama-minami and Chusei-Shudan-Bochi sites in the Yuigahama area (Kamakura, Japan), which we believe are associated with the great attack on Kamakura by Nitta Yoshisada in AD 1333. We thus estimated the marine reservoir effect on human skeletons to determine their true ages.

We show that cultural capacity is older than the first split in the modern human lineage, and at least 170,000 years old, based on data on hyoid bone morphology, FOXP2 alleles, agreement between genetic and language trees, fire use, burials, and the early appearance of tools comparable to those of modern hunter-gatherers.

We cannot exclude that Neanderthals had cultural capacity some 500,000 years ago.
