Southeast Asia was first reached by anatomically modern humans in two distinct waves before 50,000 years ago, possibly firstly before 70,000 years ago.[1] The oldest anatomically modern human fossil from Southeast Asia was found in Callao Cave, near Peñablanca, Cagayan, dated to 67,000 years old in 2010.[2] Anatomically modern humans are suggested to have reached Southeast Asia twice in the course of the Southern Dispersal migrations during and after the formation of a distinct East Asian clade, at around 50,000 years ago.[3][4]
