Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods. Some critics, particularly religious learn more · get involved. Scientists combine several well-tested techniques to find out the ages of fossils. The most important are Relative Dating, in which fossils and layers of rock are. Since genetic material (like DNA) decays rapidly, the molecular clock method can't date very old fossils. It's mainly useful for figuring out how long ago living.

All of these methods measure the amount of electrons that get absorbed and trapped inside a rock or tooth over time. Imagining the Human Future video Public Event: 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. In this way, sites that do not have radioactive or other materials for dating can be given a reliable age estimate. Here of some of the well-tested methods of dating used in the study of early humans: All of these methods measure the amount of radioactive decay of chemical elements; the decay occurs in a consistent manner, like a clock, over long periods of time. Thermo-luminescence , Optically stimulated luminescence , and Electron spin resonance.
Instead, other methods are used to work out a fossil's age. These include radiometric dating of volcanic layers above or below the fossils or by. Dating a Fossil - Carbon dating compares the ratio of carbon to carbon atoms in an organism. Learn about carbon dating and find out what the carbon
