 This first wave appears to have left dark-skinned people along its path, including isolated groups of dark-skinned people in south east Asia such as the aboriginal population of the Andaman Islands (around 400 km off the west coast of Thailand), the Semang of Malaysia, and the Aeta of the Philippines.The second wave of migration took a more northerly course, splitting somewhere in the area around what is now called Syria to sweep to interior Asia, where it split several more times in Central Asia, north of Afghanistan.The lineages that flowed into Central Asia carry M9 (Haplogroup K (Y-DNA)).
