When an organism dies it ceases to replenish carbon in its tissues and the decay of carbon 14 to nitrogen 14 changes the ratio of carbon 12 to carbon 14.

Experts can compare the ratio of carbon 12 to carbon 14 in dead material to the ratio when the organism was alive to estimate the date of its death.

The observation that certain fossils were associated with certain rock strata led early geologists to recognize a geological timescale in the 19th century.

The development of radiometric dating techniques in the early 20th century allowed geologists to determine the numerical or "absolute" age of the various strata and thereby the included fossils.

The study of fossils across geological time, how they were formed, and the evolutionary relationships between taxa (phylogeny) are some of the most important functions of the science of paleontology.

The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay.Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material.The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles.Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.

He's not one to bring girls home to meet his family, but no girl has actually stuck around long enough either. The other issue is we haven't gone on a small weekend getaway together, and I understand that he's busy with getting his master's and also wants to save his money (he just bought a house), but he seems to have no problem going on trips with his male friends. But there’s a whole lot of room between “getting upset” and wondering if you should just call it off.
