More Evidence For Hobbit Sized Species

Posted by Zonk on Tue Oct 11, 2005 04:14 PM
from the frodo-meets-science dept.
GogglesPisano writes "CNN.com reports that scientists digging in a remote Indonesian cave have uncovered a jaw bone that they say adds more evidence that a tiny prehistoric Hobbit-like species once existed." From the article: "The discovery of a jaw bone, to be reported in Thursday's issue of the journal Nature, represents the ninth individual belonging to a group believed to have lived as recently as 12,000 years ago. The bones are in a wet cave on the island of Flores in the eastern limb of the Indonesian archipelago, near Australia."

[+] Scientists Hope To Settle "Hobbit" Debate 164 comments
Several readers wrote in with news of the debate around the identity of an ancient woman whose diminutive skeleton was found on the Indonesian island of Flores in 2004. Fox News reports that Australian scientists have discovered a subterranean chamber that may contain DNA proof that will settle the question of whether "the Hobbit," as the specimen is called, actually is a representative of a new branch of the human family, or not. The find's discoverers named the putative new race Homo floresiensis. Others in the anthropological field question this identification, arguing that the meter-tall Hobbit was a modern human who had something wrong with her. In a paper just published in the Proceedings of the National Academy of Sciences, with one of the original discovery team as co-author, researchers say they have compared the Hobbit's skull to those of modern humans with various ailments such as microcephaly, and that the Hobbit is different.

    From TFA: A vocal scientific minority insists the Hobbit specimens do not represent a new species at all. They believe the specimens are nothing more than the bones of modern humans that suffered from microencephaly, a broadly defined genetic disorder that results in small brain size and other defects.

    And, at least two groups of opponents have submitted their own studies to other leading scientific journals refuting the Flores work.

    "This paper doesn't clinch it. I feel strongly that people are glossing over the problems with this interpretation," said Robert Martin, a biological anthropologist and provost of the Field Museum of Natural History in Chicago.

        So, what do these naysayers think would constitute speciation?

        How about the inability to sexually reproduce with the original species? A human with microencephaly can still sexually reproduce with another human that does not have this disorder.

        However, to call it a new species seems extremely short sighted.

        Traditionally? Speciation occurs when the decendant* line can no longer interbreed with the ancestor* line to produce viable offspring. Sickle cell anemia could be considered an inherited genetic disorder that is possibly a response to Malaria, yet the large populations of Africans that tend to have either full or partial expression of the trait are not a genetically distinct population -- they are still capable of reproducing with other Africans, Europeans, Asians, American Indians, or any other human population.

        Defining species from fossils and bones can be a bit trickier -- can you prove that this population is (a) represented by these bones, (b) genetically distinct, and (c) incapable of creating viable offspring with any other 'human' population.

        I would also like to note that there are a great variety of human populations. In Africa alone, there are groups that tend to be quite short and robust, and groups that tend to be quite tall and gracile. In a fossil record, they might bee seen as distinct species, yet we know that they can have children together. Just one of the hazards of fossils, I suppose.

        * ancestor and decendant, are, of course, relative

    There is a pygmy like species in parts of Asia and Africa. Although they are off the species Homo Sapien, they are much shorter because they do not have a growth spurt. Scientists are really interested in them because they wonder what genes cause growth and if they can be influenced. I went to a bio conference in Atlanta with my AP Biology class to listen to one. Extremely interesting. Linkage here

    Funny, I was just reading about floresiensis last night. I was greatly intrigued by the fact that the islanders' oral history includes stories about monkey-like men that closely fit the description of floresiensis man. They maintain that they were still around after the Dutch arrived in the 16th century, until about 300 years ago when they got fed up with their hijinks and set out to kill them all. Apparently there were still sightings up until the 19th century.

    The most likely explanation seems to be that a population of h. erectus found itself on the island and, through island dwarfing, ended up at their diminutive height. I find the thought of sub-human hominids suriving until that recently both creepy and fascinating. More reading at wikipedia [wikipedia.org]

    The Flying Spaghetti Monster [wikipedia.org] created the universe, starting with a mountain, trees and a midgit. This is clear proof the He was the basis of all intelligence and I demand His teachings be taught in all Kansas public schools.

    I lived in Tonga for a couple of years in the 70's and there was a tale of very small people that were living in Tonga at the time the Polynesians arrived, at least on one island. They said these people were found on 'Ata Island (the southernmost island in the group). The new Tongans apparently gave them food initially, then for whatever reason decided to kill them off and blocked them in a cave. This is quite a similar story to that told on Flores Is. where the current discoveries have been made.

    The interesting bit is that this island is uninhabited as South American slavers came in the mid-1800s and captured all the males off the island. The King then had the women and children rescued and declared the island off limits. When I was there we tried to go to the island for a scientific survey but King Tupou Fa refused. The place is only visited by occasional fishermen.

      Bone structures change over time, especially from child to adult. I think they would have been able to tell easily if it were. The main controversy here that I see from the article is that some people believe that the bones found have been that of a person who suffered from microencephaly or dwarfism.

      It could have just been a young kid? I'm sure the hobbit idea is much more interesting though...

      I am sure that idea never occured to the scientists doing the digging. You should write to them and let them know your brilliant theory. That would save everyone involved a lot of time.

        What's so insightful about this post. This guy isn't even aware that stature isn't the chief fascination with these remains, and then ends the post with some slanted bit against National Geographic. I wasn't aware that ignorance was a rewardable activity. Maybe I'll get modded +50 insightful if I say that God actually has twelve penises and practices fellatio on storm gutters.

      Not knowing the data that well, midgets and dwarfs seem to make up only a very small proportion of the population. If you sampled 100 people, what is the chance that you will get one diminutive person, let alone 20? The more skeletons they find that are similarly proportioned, the less likely it is that they represent statistical outliers, and the more likely it is that they represent the norm. Given the number of skeletons that have been found, I find the argument that they are statistical outliers to be unconvincing (though still possible, I suppose). A more likely explanation is that the small skeletons represent a significantly different population, whether it be an isolated group of Homo erectus, or an offshoot of the Home erectus line.
      • If you sampled 100 people, what is the chance that you will get one diminutive person, let alone 20?

        Depends on where you do the sampling. In Finland or an Amish country and it could be higher (Cartilage-hair hypoplasia) because these groups don't date outside of their groups enough (genetic shift) to make these "rare" exceptions rare anymore.

        If you had a group that lived alone you could get a "tribe" of little people, but they would still be human.
