continental drift

What did scientist discover about 200 million years ago

All the continents fused

What was the one giant continent known as

Pangaea

What happened to Pangaea

Broke up into 2 supercontinents

What happened about 120 million years ago

The 2 super continents broke up into the continents today

What was a result of continental drift

Climate change, habitats also changed or were destroyed. Large number of life became extinct or had to adapt to changing environment

What does biogeography suggest

Evidence that the continents were once joined. Closely related species occurring of different continents probably shared a common ancestor

What sis biogeography

The study of the distribution of existing or extinct plants and animal species in specific geographical regions on earth

What is biogeography used as

Evidence for evolution. A common population became separated due to continental drift and leads to speciation (formation of new species)

What do scientists claim about flightless birds

Developed from a common ancestor and were separated by continental drift they had to adapt to changes in environment and new species developed

What do fossils show

Supports theory of biogeography. Similar fossils have been found on the continents that make up one of the supercontinents that suggests the geological drift was after these organism where fossilised
