Homo Floresiensis Hunter

Way out in the South Pacific, near no place in particular, lies the tiny island of Flores. It has about as much land area as the Willamette Valley and has been covered with tropical rainforest for as long as anybody can tell. Insofar as the place is known at all, it’s mainly as a jumping-off point for tourists who want to visit the island of Komodo and watch big lizards eat goats.

In 2003, a discovery was made in a cave on Flores that sent a shockwave through the field of human origins. There, the remains of a previously unknown species of human were discovered that, on examination, proved to be unlike anything researchers had ever come across. What’s more, this clearly non-sapiens hominid was recent enough to have shared the island with the ancestors of the people who live there now.

The Find

Once the new species was recognized, it was given the name Homo floresiensis, “human from Flores,” and described in the literature in early 2004. The type specimen (the first of 12 to be discovered) was an adult female (nicknamed Flo, because of course she was) who stood 1.1 meters tall. That’s 3 feet, 6 inches if you live in the United States, Liberia, or Burma.

Not only is this exceptionally short for a human, she and the others that were later discovered had absurdly tiny brains. Flo’s braincase had a capacity of only 400 cc, which is maybe a quarter of what modern humans have. She also had a number of peculiar skeletal features that just don’t exist among recent human ancestors. Add to that the fact that all of the H. floresiensis remains found so far date to between 94,000 and 12,000 years ago. For comparison, our own species reached its more-or-less modern form between 100,000 and 250,000 years ago. Whatever Flo was, she wasn’t an ancestor of ours, and her race damn-near lived until Jericho was founded.

The Legends

For as long as anyone has been around to write down accounts, the people of Flores have been telling a story about the ebu gogo, or “ravenous grandmother.” This mythical creature is a 3-foot-tall hairy forest dweller who steals food, and sometimes children, from villages at night. Most of the stories are of the Hansel and Gretel type, where smart children are put in danger and eventually outwit their captors.

Because the people telling these stories have an irritating habit of not being white Christians, the stories have always been dismissed as mere folklore without any basis in reality. The discovery of Flo’s remains, dating to a time when modern humans also lived on the island, has gotten the outside world thinking that maybe there’s something to the stories after all. Indeed, while it’s tempting to turn pennies into pence for the dates, the fact that Flo lived around 10,000 BC gives some hope that her descendants might still have been present even more recently, though no younger remains have been identified.

Creation Science Weighs In

Let’s take a break from all this science and find out what idiots think is going on:

Our analyses show that the brain size of LB1 is in the range predicted for an individual with Down syndrome (DS) in a normal small-bodied population from the geographic region that includes Flores. Among additional diagnostic signs of DS and other skeletal dysplasiae are abnormally short femora combined with disproportionate flat feet. (Henneberg, et. al., 2004)

For readers who don’t speak pseudoscience, the above passage is from a paper by the Polish-American-Australian-Martian-Land of Delicious Irony biologist Maciej Henneberg, published in 2004, which tries to argue that H. floresiensis isn’t any kind of new species, but rather was a very unfortunate pygmy who had Down Syndrome. Scientific journals are in the incredibly short-sighted practice of hiding papers behind a paywall, so it isn’t feasible to link to this particular pissing match directly. Here’s a summary:

Henneberg thinks Flo was a pygmy with DS because she had a small brain, unusually short thigh bones, and flat feet, all of which are associated with DS. If this is the case, it would certainly have been nice of Henneberg to submit his paper to normal peer review, rather than publishing through the back door of sponsorship at the National Academy of Sciences by a member, 89-year-old hydrologist (and climate-change denier, and creationist, and all-around jerk) Kenneth Hsu, and not running it past any, you know, specialists in Down Syndrome along the way.
