The first apparitions of homo erectus in Southeast Asia would have occurred earlier than previously theorized: a new study that places the arrival of the first hominids in the area of Sangiran, island of Java, in a period between 1.3 and 1.5 million years ago comes to this conclusion.
These first humans migrated from Asia to Southeast Asia to reach Java at least 300,000 years later than previously believed. The Sangiran area is in fact rich in human fossils, the oldest in Southeast Asia, and is a well-known site, one of the most important to understand the evolution of the first humans in this area.
However, the chronology of the site has always remained uncertain, especially with regard to homo erectus and its first appearance in the region. Precisely for this reason, the researcher Shuji Matsu’ura, together with colleagues, has carried out a new study analyzing with various dating methods, including Uranium Lead (U/Pb) to calculate the age of various volcanic zircons found in this area.
The results that the scientist and his colleagues have obtained are therefore significantly different from the previous ones and estimate the arrival of homo erectus in this area at 1.3-1.5 million years ago while previous results estimated the arrival at 1.7 million years ago.
