Pam Eastlick for THE DEEP on line
THE LONG AND THE
SHORT OF IT
Welcome to The Deep science
and technology column where we cover topics from the deep sea
to deep space and beyond. Join us each week on Newstalk K57
on Wednesday night from 7 to 8 p.m. for exciting live science
expeditions or listen live on our web site www.thedeepradioshow.com

Two years ago, it was announced that scientists
had found the fossils of a humanoid species that grew no
larger than a three-year-old modern child. The tiny humans,
who had skulls about the size of grapefruits, lived with
pygmy elephants and Komodo dragons on a remote island in
Indonesia 18,000 years ago. The island is named Flores and
although everyone started calling them ‘hobbits,’
they are really called the Flores people. |
Flores Island is a tropical island, just like
Guam. It’s a little closer to the equator than we are
at 9 degrees south and it’s much larger than Guam, 224
miles long and 37 miles wide. It’s very mountainous with
peaks reaching 7,000 feet, and is covered with dense jungle.
There were a couple of things that raised my
scientific antennae about the initial story. One was that the
popular press kept talking about the ‘fossils’ on
Flores Island. There is a scientific maxim that states that
organisms simply don’t fossilize well in the tropics.
There are several things that must happen if you want to become
a fossil. You must be buried quickly in an environment that
keeps air away from the body. Fossilization can occur when the
remains are buried in a mudslide, covered in a thick layer of
leaves along the edge of a pond or lake, trapped in the ooze
at the bottom of lakes or oceans, or sucked into a tar pit.
Now, all these things can happen in the tropics, but there’s
one other important factor. In order to form fossils, the bone
must be gradually replaced with minerals and in areas with heavy
rainfall, this never happens. The minerals are constantly washed
away. So I did a little further digging. The skeletons on Flores
are not fossils; they’re bones.
The tiny size of these people didn’t bother
me. Animals tend toward small sizes when they are isolated on
islands. But there’s new scientific debate raging about
the one skull that was found on Flores. Some scientists are
now saying that the skull belonged to a person with microcephaly.
Microcephaly is a medical condition in which the circumference
of the head is smaller than normal because the brain has not
developed properly or has stopped growing. The scientists who
examined the skull said that it was too small even for the skeleton
with which it was associated.
But this ignores the fact
that the bones of nine individuals were found beneath
the floor of a cave on Flores and none of them were much
over three feet tall. Were there pygmy people on Flores?
And that raises my other question. Are they still there?
The source where I got the size figures for Flores Island
states, “Most of the interior of the island is unexplored.”
The native Indonesians have legends about tiny people.
The Chamorus, who apparently originated in Indonesia,
tell stories about the duendes. I maintain that if you
have an intelligent group of people who do not use fire,
they could hide for a long time on an island that’s
225 miles long and 35 miles wide. |

Join us this week as we talk about scientific
controversy and tiny people. We’ll also talk about the
possibility that the Endeavour, the ship that Captain Cook commanded
on his first voyage across the Pacific Ocean may be resting
on the seabed off Rhode Island. It’ll be a great show,
don’t miss it!
The Deep is broadcast on Newstalk K57 every Wednesday
night at 7:00 p.m. You can also listen live from our web site
www.thedeepradioshow.com. Join Jim Sullivan, Pam Eastlick, and
Peter Melyan on the deepest radio show on Earth.
