Mass extinctions have occurred five times throughout Earth's history, resulting in a significant rise in extinction rates above the background level. They are known as mass extinctions and have attracted a lot of research. The causes of these extinctions are still controversial.
Mass extinctions have occurred five times throughout Earth's history, resulting in a significant rise in extinction rates above the background level. During these events, a large group of the world's species (50% to 95%) was wiped out.
These extinctions are reflected in the fossil record and are known as mass extinctions. They have attracted a lot of research and are considered the most extreme events in a series of large extinction events.
The causes of these mass extinctions are still controversial, but in some cases, such as the most recent one about 65 million years ago, the causes are clearer.
The probable question may be:
What is the historical pattern of mass extinctions on Earth, and how many times have they occurred?
