THE identity of the tiny human-like creature discovered on the Indonesian island of Flores in 2004 has become clearer -- and more astonishing -- thanks to a new analysis by Australian and Indonesian scientists.
According to a team led by Australian National University doctoral student Debbie Argue, not only is Homo floresiensis, nicknamed the hobbit, not a deformed modern human, as a handful of critics claim, but the small-brained, long-armed biped was the first human-like creature to walk out of Africa.
And it did so nearly two million years ago, roughly 100,000 years before a species m
Hobbit-Like Human Ancestor Found in Asia
The original skeleton, a female, stood at just 1 meter (3.3 feet) tall, weighed about 25 kilograms (55 pounds), and was around 30 years old at the time of her death 18,000 years ago. The skeleton was found in the same sediment deposits on Flores that have also been found to contain stone tools and the bones of dwarf elephants, giant rodents, and Komodo dragons, lizards that can grow to 10 feet (3 meters) and that still live today.
The findings, recently reported in the Journal of Human Evolution, back a similar argument made in the journal Science in 2007 that the hobbit's unique wrist anatomy suggested the 1m-tall creature came from a lineage that lived long before the common ancestor of people and Neanderthals.

Because the island is so isolated, creatures morphed into either dwarf or giant forms, including a little elephant called a pygmy Stegodon, and Komodo dragons, giant lizards and turtles that were almost as large as the elephants. But this is the first such incident noted in a human species, showing that humans are subject to the same evolutionary processes as all other mammals.
"On small islands it is common for animals larger than a rabbit to shrink, while very small mammals get bigger," Brown said.
The amount of food available and the absence of predators causes these odd size changes, the advantage being that you need less food to survive when you're small. For example, the elephants likely became very small because they had limited food, but no animals threatening to eat them.

All humor aside, that is pretty curious. Thanks for pointing that out.

– suggest that Homo floresiensis diverged from the Homo sapiens evolutionary line in the Early Pleistocene, or even the Pliocene, nearly 2 million years ago, meaning that Homo floresiensis did not share an immediate ancestor with modern humans.

Wait i'm confused
the article says the hobbits came from homo erectus but then shrunk because they were isolated on an island?????
what?

what's the logic here?

Negritos
Main article: Negrito
Negritos in Southeast Asia (including the Batak and Aeta of the Philippines, the Andamanese of the Andaman Islands, and the Semang of the Malay Peninsula), and occasionally Papuans and Melanesians in adjacent Oceania, are sometimes called pygmies (especially in older literature).[citation needed]
Negritos share some common physical features with African pygmy populations, including short stature and dark skin. The name "Negrito", from the Spanish adjective meaning "small and black", was given by early explorers.
The explorers who named the Negritos assumed the Andamanese they encountered were from Africa. This belief was, however, discarded by anthropologists who noted that apart from dark skin and curly hair, the Andamanese had little in common with any African population, including the African pygmies.[23] Their resemblance to some Africans, it is generally believed, is due to adaptation to a similar environment, rather than shared origins.[24]
Their origin and the route of their migration to Asia is still a matter of great speculation. They are genetically distant from Africans,[24] and have been shown to have separated early from Asians, suggesting that they are either surviving descendants of settlers from an early out-of-Africa migration, or that they are descendants of one of the founder populations of modern humans.[25]
T'rung
Frank Kingdon-Ward in the early 20th century, Alan Rabinowitz in the 1990s, P. Christiaan Klieger in 2003, and others have reported a tribe of pygmy Tibeto-Burman speakers known as the T'rung inhabiting the remote region of Mt. Hkakabo Razi in Southeast Asia on the border of China (Yunnan and Tibet), Burma, and India. A Burmese survey done in the 1960s reported a mean height of an adult male T'rung at 1.43 m (4'6") and that of females at 1.40 m (4'5"). These are the only "pygmies" noted of clearly East Asian origin. The cause of their diminutive size is unknown, but diet and endogamous marriage practices have been cited. The population of T'rung pygmies has been steadily shrinking, and is now down to only a few individuals.[26][27]
Australia Barrineans
Short statured aboriginal tribes inhabited the rainforests of North Queensland, Australia, of which the best known group is probably the Tjapukai of the Cairns area.[28] These rainforest people, collectively referred to as Barrineans, were once considered to be a relict of the earliest wave of migration to the Australian continent, but this theory no longer finds much favour.[29] The Rainforest People tended to live in the first variety of Jykabita, a wood and mud structure renowned for incubation of plants.[30]
From the 1940s until the 1960s, it was fairly widely known there were pygmies in Australia. They lived in North Queensland and had come in from the wild of the tropical rainforests to live on missions in the region. This was a fact recorded at the time not only in anthropological textbooks and articles but also in popular books about the Australian Aborigines. There was even an award-winning children's book tracing their origins. The more famous photographs of the Australian pygmies were reproduced in both the academic and the popular literature.
At the time, there was controversy about their origins but not over the fact of their existence. In 1962, the first volume of Manning Clark's History of Australia recorded their presence on its first two pages and repeated the then influential anthropological theory about their origins and their place in the waves of migration of hunter-gatherer peoples from Asia who populated the Australian continent in the millennia before the British arrived in 1788.
