, nicknamed the “hobbit” for its small size, became extinct around 50,000 years ago – tens of thousands of years earlier than originally thought.
The new study dated layers of volcanic ash and calcite directly above and below the fossils. Flores is one of many Wallacean islands, which lie east of Wallace's Line and west of Lydekker's Line.
Wallacean islands are interesting because they have rarely, if ever, been connected via land bridges to either the Asian continent to the west or the Greater Australian continent to the east.
This longstanding separation from the surrounding continents has severely limited the ability of animal species to disperse either into or away from the Wallacean islands.
Remains of individuals who died over 2 million years ago would be expected to have undergone a high degree of fossilization (i.e., mineralization).
Now, one of three articles on reports that radiometric dating of the cave sediments within which the bones were found as well as of three teeth indicates that this species existed much more recently, up to at least between 236,000 and 335,000 years ago.
Dating based on anatomical characteristics alone can only provide a very broad approximation of a specimen’s age, especially when considering a relatively poorly understood taxon (an evolutionary group of related species), such as hominins.
Another discordant note was the condition of the bones, which were barely fossilized.
The ancient city of Gezer is mentioned in the biblical account of King Solomon’s fortifications, as well as in several ancient Egyptian and Assyrian texts.
is a high altitude glacial lake in the Uttarakhand state of India.
It lies in the lap of Trishul massif and is famous for the hundreds of human skeletons found at the edge of the lake.
While living on Flores, he identified dozens of archeological sites and conducted excavations at many of these, including the now famous site of Liang Bua where the "hobbits" of human evolution were discovered ( from Java was likely behind making the stone tools found on Flores and may have reached the island around 750,000 years ago.
At the time, paleoanthropologists took little notice of Verhoeven's claims or if they did, they discounted them outright.
