Purdue researchers determine age of fossilized human ancestor Far from being data, these dates are actually interpretations of the data. Their measurement que, generally used to estimate the age of. "By dating the sediments surrounding the fossil skeleton, we have. was using radioactive isotopes in sediment to determine the age of rivers and caves.
Dating Methods Answers in Genesis As discussed before, the assumptions influence the interpretation of the data. Fossils and rocks do not come with dates stamped on them. Radiometric dating uses ratios of isotopes in rocks to infer the age of the rock.
Accuracy of Fossils and Dating Methods - ActionBioscience. There are three main assumptions that must be made to accept radiometric dating methods. Some skeptics believe that all fossils are the same age. Modern phylogenetic trees have no input from stratraphy, so they can be used in a broad way to make comparisons. Radiometric dating involves the use of isotope series, such as.
