• “Mythological” human creatures

of the Island of Flores Indonesia

• Ebu means “grandmother”

• Gogo means “he who eats

everything”

• Small hairy creatures

• Ate everything raw

• Had their own language but

learned the human language as

well

Page 6: Homo Floresiensis presentation

• 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

Page 7: Homo Floresiensis presentation

• 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

Page 8: Homo Floresiensis presentation

• 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

Page 12: Homo Floresiensis presentation

• 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

Page 13: Homo Floresiensis presentation

• 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

Page 14: Homo Floresiensis presentation

• 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

Page 16: Homo Floresiensis presentation

Island dwarfism- process that results from long-term

isolation on a small island with limited food resources and

lack of predators.

Page 17: Homo Floresiensis presentation

• 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.
