What Can You Say About The Origin Of Life? The origin of life is a result of a supernatural event—that is, one irretrievably beyond the descriptive powers of physics, chemistry, and other science. Life, particularly simple forms, spontaneously and readily arises from nonliving matter in short periods of time, today as in the past. Why
What Cannot Become A Fossil? For an organism to become a fossil, it must not decompose or be eaten. This can happen if the organism either lives within or is moved to a place where it can be buried and kept from decaying. When an organism is buried quickly, there is less decay and the

What Cannot Be Determined From The Fossil Record? The fossil record cannot accurately determine when one species becomes another species. However, two hypotheses regarding speciation also exist. Phyletic speciation suggests that abrupt mutations in a few regulatory genes occur after a species has existed for a long period of time. What are the limitations of

Index fossils are the basis for defining boundaries in the geologic time scale Which fossil could be a good index fossil? Trilobites are
What Can Fossils Tell Us About Past Environments? By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. How
What Can Fossils Not Tell Us? Fossils also show how animals changed over time and how they are related to one another. Fossils can’t tell us everything. While fossils reveal what ancient living things looked like, they keep us guessing about their color, sounds, and most of their behavior. What if there were no fossils?
What Can Fossils Tell You? Fossils are the remains or traces of ancient life that are usually buried in rocks. Examples include bones, teeth, shells, leaf impressions, nests, and footprints. This evidence reveals what our planet was like long ago. Fossils also show how animals changed over time and how they are related to one
