Diversity of life on Earth from "summary" of Biology by Neil A. Campbell
The incredible variety of living organisms that inhabit our planet is a testament to the diversity of life on Earth. From the tiniest microorganisms to the largest animals, the range of forms and functions found in nature is truly astounding. This diversity is not just limited to the differences in size or shape, but also extends to the ways in which organisms interact with their environment and each other. One of the key principles of biology is that all living things share a common ancestry, despite their vast differences in appearance and behavior. This concept, known as evolution, explains how the diversity of life on Earth has arisen over billions of years through a process of natural selection. Through this mechanism, organisms that are best adapted to their environment are more likely to survive and reproduce, pass...
