The Great Rift Valley is where tectonic plates started pulling apart. It provides evidence because the zones have fossil sites that document the evolution of early human ancestors and mammals during the Paleogene periods. This happened about 20 million years ago.

Antarctica shows evidence of climatic shifts and glaciers during the Cenozoic Era. Fossils from this era show that Antarctica was once warm and had forests. This is a good and prime example of global climate change over millions of years.

The cave paintings were created about 17,000 years ago. This shows evidence of early human culture and the development of modern mammals during the Holocene times. They show the early environments of mammals during the Ice age.
