• Ebu Gogo would raid crops, ad
crossed the line when a baby was
stolen and was eaten
• For this action they chased them
away
• They offered them bales of dry grass
as fodder
• They came back a few days later
with a burning bale of grass
• Ran the Ebu Gogo’s out of the cave
• Last seen heading west in the
direction of Liang Bua, where the
hobbit was found

• Father Theodor Verhoeven
• Years ago Vergoeven was brought to Flores to teach religion
• First used the cave as an elementary school
• Verhoeven then decided that the floor was a great excavation
project in 1950
• In 1960 large amounts of stone artifacts and pottery was found

• The first excavation lead by Raden Panji Soejono
• Director of ARKENAS
• National Research Centre for Archaeology
• Was planning to dig through the last 100,000 years
• It was believe this was the point in time there were humans,
although there were little evidence about the arrival of modern
humans and extinction of earlier human populations.

• Small body
• arm bone to leg bone ratio, baboon like
• was likely to adapt in trees than modern humans
• stout long-bone shafts and arm-bone to thigh bone ratio
• are more in accord with a four legged walker
• orients the long axes of its limbs bone oblique to the force of gravity

• Skull
• Very small with a very small vertically face
• Forehead is relatively high
• The cast of LB1 skull shows a very small brain
• Brain volume of 380cc comparable to living chimpanzees and below to
gorillas

• Tooth suggest wide range of foods like vertebrates, fruits, seeds,
tubers, and herbs
• Lower premolars
• Elongated and have double roots
• Upper premolars
• Correspondingly unique shape
• Both upper and lower rows are relatively narrow and the front teeth small
• Given its small body size insects may have provided a greater
percentage of the diet that large extinct hominids

• Homo floresiensis species isn’t a separate species at all,
but instead belonged to a group of modern humans
whose size was restricted because they had a disease
• Microcephaly
• An abnormally small head due to failure of brain growth

Island dwarfism- process that results from long-term
isolation on a small island with limited food resources and
lack of predators.

• Remains found were not
that of a new species at
all.
• Ancestors of modern human
pygmies who live on island
currently
• The features in LB1’s
cranium previously said to
be diagnostic of a new
species are still found in
the Rampasasa pygmies
on the island today.
