The chances of fossilization are very slim, because it requires that the remains be quickly buried and be kept in an oxygen-free environment.
Scavenger and bacterial activity must be prevented so that decomposition is limited.
They do not provide “exact” dates for the materials.
The DNA can then be analyzed to learn more about the organism.Any living organism can become fossilized, including bacteria, plants, and animals.Radiometric methods, such as radiocarbon dating and radiopotassium dating utilize the regular radioactive decay of isotopes from one form to another.Measuring the ratio of the two forms provides date information.Response: The two major types of dating include relative methods and absolute methods.
Relative methods focus on comparison of fossils, strata, or other artifacts to determine which is older and which is younger.It is founded on unprovable assumptions such as 1) there has been no contamination and 2) the decay rate has remained constant.By dating rocks of known ages which give highly inflated ages, geologists have shown this method can’t give reliable absolute ages.Response: Niels Stensen created the Law of Superposition, which is the foundation for relative dating methods.This law states that the youngest objects or layers are on the top, while the older objects and layers are deeper.In addition, local climatic and environmental conditions determine whether fossilization will occur, so that there is differential preservation among different locations.
