The major evolutionary episode corresponding most closely in time with the formation of Pangaea was the Permian Extinctions.
The Permian Extinctions happened around 300 million years ago and lasted for around 15 million years. It eliminated over 95 percent of water life and 70 percent of species on land. It was one of the largest extinctions in the history of Earth.

The scientific design in which has limitations
due to oversimplification is the statement “in a study of the effect of lawn
fertilizer on the health of a backyard pond, biologists grow two colonies of
duckweed in a large flask to represent pond ecosystems”. Oversimplification is
an overview and generalization of a statement to miscomprehension,
misperception or even error. It overlaps the true statement.
