What has three hypothesis
To explain the source of all the biodiversity on earth and the amount of biodiversity found on earth overtime
First hypothesis
All life appeared at the same time in Earth’s history. As a result, biodiversity has remained the same throughout earths history
Second hypothesis
Present day forms of life arose from other forms of life over a considerable amount of time. As a result, low biodiversity has increased throughout earths history
Third hypothesis
All life on Earth appeared at the same time in earths history. However, current life forms are survivors of one or more catastrophic events that wiped out many of the other lifeforms that once inhabited earth. As a result, biodiversity has decreased throughout earths history
Guiding question
