A series of radiometric determinations done subsequently has yielded a date of 1.88 mya.
Radiocarbon samples from these excavations yielded a date of 12,000 years.
They include traces of kilns on the south side of Room 47 in the Burnt Palace, together with red glass ingots and slag, which after a radiocarbon analysis yielded a date of 425 +/- 50 BC.
This yielded a date of 440 (SD 138) ky ago for the divergence of the human and Neandertal mtDNA lineages.
When all estimates yield a date of birth within a 3-year range, the average was used unless one or two estimates were judged to be superior to the others.
The caption accompanying the print explains the meaning of a picture that would otherwise be incomprehensible and yields a date, to the delight of scholars.
Tracing back its expansion (assuming a constant decrease of expansion speed due to the nebula's mass) yielded a date for the creation of the nebula several decades after 1054, implying that its outward velocity has decelerated less than assumed since the supernova explosion.
The former yields an average date of 3520 (±540) BC and the latter an average date of 3400 (±200) years BC, both of which, within overlapping errors, suggest the main settlement occurred during the Final Neolithic.
Assuming that this substitution rate has been constant since the Salicoid duplication yields an estimated date of the genome duplication some 150 mya.
At the site of Palli Aike, on the Strait of Magellan, the earliest cultural horizon has yielded a radiocarbon date of about 8000 bc, indicating that man reached the southern extremity of the New World well before 10,000 years ago.
