This method compares the amount of genetic difference between living organisms and computes an age based on well-tested rates of genetic mutation over time. Older dates may change by a few million years up and down, but younger dates are stable.

Many natural history museums and universities worldwide offer public participation programs in dinosaur events, such as fossil hunting or fossil cataloguing. Fossils can irkutsk dating show us how major crises, such as mass extinctions, happened, and how life recovered after them.

Phylogenetic trees are drawn up mathematically, using lists of morphological external form or molecular gene sequence characters. Since then, geologists have made many tens of thousands of radiometric age determinations, and they have refined the earlier estimates.

Biologists actually have at their disposal several independent ways of looking at the history of life - not only from the order of fossils in the rocks, but also through phylogenetic trees.

This is consistent with the young-earth view that the entire macrofossil record up to the upper Cenozoic is the product of the Genesis Flood and therefore such fossils should share a common 14 C age.
