Ancient Tools May Shed Light On the Mysterious 'Hobbit' (sciencemag.org)

sciencehabit writes: The "hobbit" had neighbors. Back in 2004, researchers announced the discovery of this tiny, ancient human, which apparently hunted dwarf elephants with stone tools on the Indonesian island of Flores 18,000 years ago. Its discoverers called the 1-meter-tall creature Homo floresiensis, but skeptics wondered whether it was just a stunted modern human. In the years since, researchers have debunked many of the "sick hobbit" hypotheses. Yet scientists have continued to wonder where the species came from.

Now, an international team originally led by the hobbit discoverer reports stone tools, dated to 118,000 to 194,000 years ago, from another Indonesian island, Sulawesi, likely made by another archaic human—or possibly by other hobbits. "It shows that on another island we have evidence of a second archaic early human," says paleoanthropologist Russell Ciochon of the University of Iowa in Iowa City, who was not involved with the work. The discovery makes the original hobbit claim appear more plausible, he says, by suggesting that human ancestors may have island-hopped more often than had been thought.

      There was an ice age from about 200,000 BCE to 135,000 BCE so the sea distances were probably not as great. Borneo was apparently connected to mainland Asia and Sulawesi is just east of Borneo, with mountains along the adjoining coast that would be visible at some distance.

    It just always seemed more likely, given the multitudes of places that hominids evolved before mass transportation was a thing, that our species would vary more widely in size.

    We have the pygmy tribes in which the average male is 1.5m tall and upward human extremes of 2.3m, but the variation in size really only becomes extraordinarily diverse at the Super Family level.

      Yes, I'm an overweight white guy who grew up in the northern USA. I'm currently living in Southeast Asia and if I'm outdoors during the day (i.e. without air-conditioning) for more than a few hours then I start to get heat stroke.

      During the day the temperature typically gets up to a degree or two above 30C (high 80s Fahrenheit) - which doesn't sounds too bad. But the humidity is almost always well above 80% - which puts it into the "Danger" zone of the heat index. The Danger zone means "heat cramps or heat exhaustion likely, and heat stroke possible with prolonged exposure and/or physical activity".

      I assume that the researchers have already been thinking along those lines. But it would definitely be worth exploring whether there was particularly high heat and humidity in that part of the world at that time.
