INDONESIA: The first modern humans in Australia may have migrated there from Southeast Asia via the islands of Indonesia. Two new skull fragments from Alor Island, dating to between 17,000 and 12,000 years ago, hint that the Wallacean Islands may have been a stop on this migration route. One peculiar aspect of these skulls is their small size. This may be due to the “island effect.” This theory posits that when humans and other mammals live on islands lacking sufficient nutrition, they gradually become smaller.
