Fossils are the remains or traces of ancient organisms that have been preserved in a sedimentary rock. Fossils can be used as evidence to support the theory of evolution. Fossils provide information about how organisms have evolved over time, and how they were adapted to their environment. Fossils also provide evidence of the changes in the physical characteristics of species over geologic time.
Fossils provide direct evidence of the history of life on earth. They provide information about the age, size, and shape of organisms, their evolutionary relationships, and the environments in which they lived. Fossils also provide evidence of the process of evolution and the development of new species. By studying the fossil record, scientists have been able to trace the evolutionary history of many plants and animals. Fossils provide evidence that species have changed over time, and that different species have evolved from common ancestors. This is illustrated by the fossil record, which shows that while some species have remained relatively unchanged over time, others have changed dramatically. For example, the fossil record shows that horses evolved from small, four-toed mammals over millions of years, becoming the large, one-toed animals we are familiar with today. Fossils also provide evidence for the theory of natural selection. By studying fossils, scientists have been able to understand how organisms have adapted to their environments over time. This helps us to understand why some species have become extinct while others have been able to survive and even thrive in changing conditions.
