The DNA can then be analyzed to learn more about the organism.

Any living organism can become fossilized, including bacteria, plants, and animals.

Absolute dating uses chemical and physical processes to provide a date range for an object, fossil, or site.

Absolute methods include radiometric and non-radiometric methods.

Non-radiometric methods utilize other processes to assess a date.

Non-radiometric methods include dendrochronology, or tree-ring dating, amino acid dating, fission track, paleomagnetic dating, electron spin resonance, and luminescence.

These specific required conditions explain why fossils are so rare. : The Making of the Biological Past Response: Since fossilization requires very unique circumstances, fossils are very rare.

This law states that the youngest objects or layers are on the top, while the older objects and layers are deeper.

This law is the important for stratigraphic dating, because fossils, bones, or other objects incorporated into these layers can be compared to each other to determine relative ages.

Those materials in the lowest layers are the oldest, while those that are in the highest levels are the youngest.

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.

Other relative methods include chemical dating, biostratigraphic or faunal dating, and cultural dating.
