Explain the method of radio-carbon dating to determine the age of plant and animal fossils
When we speak of the element Carbon, we most often refer to the most naturally abundant stable isotope 12 C. Although 12 C is definitely essential to life, its unstable sister isotope 14 C has become of extreme importance to the science world. Radiocarbon dating is the process of determining the age of a sample by examining the amount of 14 C remaining against its known half-life, 5, years. The reason this process works is because when organisms are alive, they are constantly replenishing their 14 C supply through respiration, providing them with a constant amount of the isotope.
Lake Turkana has a geologic history that favored the preservation of fossils. Scientists suggest that the lake as it appears today has only been around for the past , years. The current environment around Lake Turkana is very dry.
