Fossils tell us when organisms lived, as well as provide evidence for the progression and evolution of life on earth over millions of years.
LEARNING OBJECTIVES
Synthesize the contributions of the fossil record to our understanding of evolution
KEY TAKEAWAYS
Key Points
Fossils are the preserved remains or traces of animals, plants, and other organisms from the past.
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
Usually only a portion of an organism is preserved as a fossil, such as body fossils (bones and exoskeletons ), trace fossils (feces and footprints), and chemofossils (biochemical signals).
Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.

fossils are the preserved traces of living organisms.we find the age of the fossil by two ways by isotope and by the layer of soil .If it is in the top near the soil we come to known that they are only few years before and its under then it would be older than that.It is the evidence for evolution.
