Flores on the News
today:
Shall a
theory about HUMAN EVOLUTION needs to change??
My name Peter Paka
(originally from Flores island of Indonesia) received so many
emails questioning me with the new found ancient human species on
my beloved homeland "Flores Island". Msn.com opens my
mind and brain to start reading the hot news about this articles.
It kept me first minutes spent to think and not to believe since I
was at the school learned that the most ancient human fossils are
only found in Java and other part of the world. But today, Henry
Gee of Nature magazine and Professor Chris Stringer of London's
Natural History Museum have strongly recommend scientists to
analyze and rewrite the history of human evolution. My friend Paul
Boleng who was a guide conducting the several scientist into Liang
Bua have been told that the information he gave me before now
become the world's new.
With this new human species found not far from our Flores houses, It may
raise a question SHALL A THEORY ABOUT HUMAN EVOLUTION needs to change????
3FT TALL (90 CENTIMETER-TALL)
Scientist on their press conference said the ancient adult female skeleton
measures 3ft tall or 90cm tall found in a cave is believed 18,000 years old.
It smashes the long-cherished scientific belief that our species, Homo
sapiens, systematically crowded out other upright-walking human cousins
beginning 160,000 years ago and that we've had Earth to ourselves for tens
of thousands of years. It wakes up our mind that AFRICA, the acknowledged
cradle of humanity, does not hold right answer on question of how - where -
we came to be.
"This finding really does rewrite our knowledge of human
evolution," said Chris Stringer, who directs human origins studies at
the Natural History Museum in London. "And to have them present less
than 20,000 years ago is frankly astonishing."
Shortest member of human family
Scientists called the dwarf skeleton "the most extreme" figure to
be included in the extended human family. Certainly, she is the shortest.
She is the best example of a trove of fragmented bones that account for as
many as seven of these primitive individuals that lived on the equatorial
island of Flores, located east of Java and northwest of Australia. The
mostly intact female skeleton was found in September 2003.
Scientists have named the extinct species Homo Floresiensis, or Flores Man,
and details appear in Thursday's issue of the journal.
The specimens' ages range from 95,000 to 12,000 years old, meaning they
lived until the threshold of recorded human history and perhaps crossed
paths with the ancestors of today's islanders.
Flores Man was hardly formidable. His grapefruit-sized brain was two-thirds
smaller than ours, and closer to the brains of today's chimpanzees and
transitional pre human species in Africa than vanished 2 million years ago.
Yet Flores Man made stone tools, lit fires and organized group hunts for
meat. Bones of fish, birds and rodents found near the skeleton were charred,
suggesting they were cooked.
All this suggests Flores Man lived communally and communicated effectively,
perhaps even verbally.
"It is arguably the most significant discovery concerning our own genus
in my lifetime," said anthropologist Bernard Wood of George Washington
University, who reviewed the research independently.
Discoveries simply "don't get any better than that," proclaimed
Robert Foley and Marta Mirazon Lahr of Cambridge University in a written
analysis.
Questions over classification
To others, the species' baffling combination of slight dimensions and coarse
features bears almost no meaningful comparison either to modern humans or to
our larger, archaic cousins.
They suggest that Flores Man doesn't belong in the genus Homo at all, even
if it was a recent contemporary. But they are unsure where to classify it.
"I don't think anybody can pigeonhole this into the very simple-minded
theories of what is human," anthropologist Jeffrey Schwartz of the
University of Pittsburgh. "There is no biological reason to call it
Homo. We have to rethink what it is."
For now, most researchers have been limited to examining digital photographs
of the specimens. The female partial skeleton and other fragments are stored
in a laboratory in Jakarta, Indonesia.
Researchers from Australia and Indonesia found the partial skeleton 13
months ago in a shallow limestone cave known as Liang Bua. The cave, which
extends into a hillside for about 130 feet (40 meters), has been the subject
of scientific analysis since 1964. Fenced off and patrolled by guards, it is
surrounded by coffee farms.
Older stone tools and other artifacts previously found on the island suggest
that Flores Man is part of a substantial archaic human lineage.
"So the 18,000-year-old skeleton cannot be some kind of 'freak' that we
just happened to stumble across," said one of the discoverers,
radiocarbon dating expert Richard G. Roberts of the University of Wollongong
in Australia.
Peculiar environment
But the environment in which Flores Man lived was indeed peculiar, and
scientists say it probably contributed to the specimen's unusually small
dimensions.

Peculiar environment
But the environment in which Flores Man lived was indeed peculiar, and
scientists say it probably contributed to the specimen's unusually small
dimensions.
Millennia ago, Flores was a kind of a looking-glass world, a real-life
Middle-earth inhabited by a menagerie of fantastical creatures like giant
tortoises, elephants as small as ponies and rats as big as hunting dogs.
It even had a dragon, although they were giant lizards like today's
carnivorous Komodo dragons rather than the treasure-hoarding Smaug described
by novelist J.R.R. Tolkien in his "Lord of the Rings" trilogy.
Artifacts suggest that a big-boned human cousin, Homo erectus, migrated from
Java to Flores and other islands, perhaps by bamboo raft, nearly 1 million
years ago.
Researchers suspect that Flores Man probably is a descendant of Homo erectus
that was squeezed by the pressures of natural selection.
Dwarfism in nature
Nature is full of mammals - deer, squirrels and pigs, for example - living
in marginal, isolated environments that gradually dwarf when food isn't
plentiful and predators aren't threatening.
This is the first time that the evolution of dwarfism has been recorded in a
human relative, said the study's lead author, Peter Brown of the University
of New England in Australia.
Just how this primitive, remnant species managed to hang on is uncertain.
Inbreeding certainly would have been a danger. Geologic evidence suggests a
massive volcanic eruption sealed its fate 12,000 years ago, along with other
unusual island species like the dwarf elephant species, stegodon.
Now, scientists are more puzzled by the specimen's jumble of features that
appear to be borrowed from different human ancestors.
Clues from the skeleton
This much is clear: Its worn teeth and fused skull show it was an adult. The
shape of the pelvis is female. The skull is wide like that of Homo erectus.
But the sides are rounder and the crown traces an arc from ear to ear. The
skull of Homo erectus has straight sides and a pointed crown, they said.
The lower jaw contains large, blunt teeth and roots like Australopithecus, a
prehuman ancestor in Africa more than 3 million years ago. The front teeth
are smaller and more like modern human teeth.
The eye sockets are big and round, but unlike other members of the Homo
genus, it has hardly any chin or browline.
The rest of the skeleton looks as if it walked upright, but the pelvis and
the shinbone have primitive, even apelike features.
Bones from the species' feet and hands have not yet been found. Delicate
artifacts found in the cave were described as "toy-sized" versions
of stone tools made by Homo erectus. They suggest that Flores Man retained
intelligence and dexterity to flake small weapons with sharp edges, even if
its body shrunk over time.
"I've spent a sleepless night trying to figure out what to do with this
thing," said Schwartz. "It's a mind-blower. It makes me think of
nothing else in this world."
Even more speculative is whether Flores Man met with modern humans, and what
might have happened.
Folklore experts have reported persistent legends of little people living on
Flores and nearby islands. Islanders called the creature "Ebu Gogo"
and say it was about 3 feet tall.
