the first large bodied hominin. 2mya.
when did h. ergaster first appear and where did they establish?
2 million years ago. Africa
when did H. erectus appear and where did they establish?
1.7-16 mya. Africa and some long term populations in Europe and Asia
how long was H. erectus in Africa? Asia? Europe?
Africa until 600,000 years ago, Asia until 100,000 years ago and Europe until 500,000 years ago.
what are lumpers?
people who group fossils together in the same genesis despite small or large differences.
what are splitters?
people who split fossils into many different genesis despite similarities.
differences between us and H. Erectus? (skull)
heavy browridge, low receding forehead, lack a chin, sagittal ridge (top of the head) and a pentagonal shape.
how old is the Nariokotome boy
1.65mya.
what are the names of the three homo erectus sites in china
Nihewan basin, Yunxian and Zoukoudien
what did early researchers use to determine the age of the oldest Javanese hominin fossils?
Biochronology
Causes of global reduction in forests
Loss of habitat provided a greater reason for bipedalism, thermoregulation, and a larger vein.
Dmanisi (Hominin)
Dmanisi hominin’s had very small brains but are tall
Nihewan Basin (Site)
Site with animal bones and stone tools but no hominin bones.
Zhoukoudien
Hominin site in Asia.
Davidson Black
Identified hominin fossils.
Java
an island where the first homo erectus fossil was found.
Eugene Dubois
Credited for the Java man
Daka (skull)
Homo erectus fossil found in Ethiopia. 1mya.
Bodo cranium
Skull found in Ethiopia with cut marks on the bone.
Kabwe/Broken hill (skull)
Homo erectus skull found with an approx. 1300cc.
Acheulian Industry
The use of hand axes 1.5mya. Shows an advance of brain size. First “formal tool”.
Mental template
The idea that someone already has an idea of what they are making before they make it.
How did the hominins get to java.
The ice age caused the water levels to drop allowing shallower parts of the oceans to become bare. This is called the Sunda Shelf.
What was the Wallace line
The line that separated the the Sunda (Africa) and Sahul (Australia).
Homo floresiensis
Very short with very small brain probably caused by Island dwarfism. Found in Flores
What is island dwarfism
When people/animals shrinks based of one another.
How did hominins get to Flores
Jump dispersal.
What is insular gigantism
When people/animals grow based on one another.
