Researchers say 'Hobbit' shrank over generations

Japanese scientists say that a diminutive species of early human whose remains were found on the Indonesian Island of Flores may have shrunk as a result of the way it adapted to its environment.

The creature - known as homo floresiensis - was discovered in 2003.

The new study (published in the Journal of the Royal Society) says it was an early human species which shrank over many generations by a process known as island dwarfism, in which species become smaller when they are isolated and resources are limited.

But other scientists say the creature's ancestor is a small-brained ape-like creature.

Another theory is that homo floresiensis were modern humans whose growth was restricted by disease.

Peneliti sebut 'Hobbit' menyusut dari generasi ke generasi

Peneliti dari Jepang mengatakan bahwa spesies kecil manusia awal yang fosilnya ditemukan di Flores mungkin menyusut karena mereka berusaha beradaptasi dengan lingkungan.

Makhluk yang dikenal dengan nama homo floresiensis itu ditemukan pada tahun 2003.

Penemuan baru (yang diterbitkan oleh Journal of the Royal Society) menyebutkan bahwa spesies manusia awal menyusut dari generasi ke generasi melalui proses yang disebut pengerdilan

pulau, di mana spesies tersebut mengecil saat mereka terisolasi dan sumber daya terbatas.

Namun sejumlah ilmuwan lain mengatakan bahwa nenek moyang spesies itu adalah makhluk dengan otak berukuran kecil dan menyerupai kera.

Teori lain menyebutkan bahwa homo floriensis adalah manusia modern dengan pertumbuhan terbatas karena suatu penyakit.
