Radiometric dating hoax
Potassium-argon dating, for instance, can provide the age of a specimen by clocking the rate at which radioactive isotopes of these elements have decayed.When radiometric methods cannot be applied, investigators may still ascribe a relative age to a fossil by relating it to the other contents of the deposit in which it was found.For example, similar fossils were found during the early 20th century at several different locations in Java: Kedung Brubus, Mojokerto (Modjokerto), Sangiran, Ngandong (Solo), Sambungmacan (Sambungmachan), and Ngawi.Another series of finds was made in China beginning in the 1920s, especially in the caves and fissures of Peking man; virtually all of these remains were subsequently lost by 1941 during the Sino-Japanese War (1937–45), though casts of them still exist.One of the oldest European hominin fossils is an isolated mandible (lower jawbone) with teeth, found in 1907 in a sandpit just north of Mauer, Germany, near Heidelberg.Dating to about 500,000 years ago, it has been given a variety of names over the years (Heidelberg jaw), but its exact relationship to other fossils remains uncertain, partly because no associated cranium was found.More convincing evidence for the presence of in Europe has come from Ceprano in central Italy, where a skull lacking its face was found in 1994.
Several years later, near where the skull was discovered, he found a remarkably complete and modern-looking femur (thighbone).
Some investigators have come to regard the Mauer mandible as representing ) that is slightly more advanced in its anatomy than the African and Asian populations.
Another fossil that may tentatively be grouped with the Mauer mandible is a lower leg bone (tibia) found in 1993 during excavations at Boxgrove, West Sussex, England.
Since 1970 a number of important fossils have been unearthed at localities on the eastern shore of Lake Turkana (Lake Rudolf) in northwestern Kenya, now commonly referred to as the Turkana Boy” (KNM-WT 15000) was found nearby at Nariokotome, a site on the northwestern shore of Lake Turkana.
The remains of this juvenile male have provided much information about growth, development, and body proportions of an early member of the species., the situation in Europe is less clear.
