Detailed explanation-1: -Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
Detailed explanation-2: -Fossils provide important evidence for evolution and the adaptation of plants and animals to their environments. Fossil evidence provides a record of how creatures evolved and how this process can be represented by a ‘tree of life’, showing that all species are related to each other.
Detailed explanation-3: -Fossils. Fossils provide solid evidence that organisms from the past are not the same as those found today, and fossils show a progression of evolution. Scientists determine the age of fossils and categorize them from all over the world to determine when the organisms lived relative to each other.
Detailed explanation-4: -These fossils are different from body fossils that preserve the actual remains of a body such as shells or bones. Trace fossils are classified based on an organism’s shape and behaviors rather than on its physical form.
Detailed explanation-5: -Cross dating is a method of using fossils to determine the relative age of a rock. Fossil remains have been found in rocks of all ages with the simplest of organisms being found in the oldest of rocks. The more basic the organism the older the rock is.
