The previous value of the half-life of Carbon-14 (¹⁴C) was 5,568 years before it was revised to the currently accepted value of 5,730 years. This radiometric dating tool is crucial for determining the age of organic materials up to about 50,000 years old. The adjustment in the half-life value reflects improvements in radiocarbon dating technology and calibration, which have enhanced the accuracy of archaeological and geological age determinations. This refinement helps provide a more accurate timeline of historical and prehistoric events, influencing not just archaeological but also geological and environmental research.

Potassium-Argon dating is the suitable technique for dating early hominin fossils in East Africa. This radiometric method is used to date volcanic rock layers above and below archaeological sites, which can indirectly date the fossils embedded within those layers.
Potassium-Argon dating is especially useful for dating ancient sites because it can be applied to rocks and minerals that are millions of years old, which is often the case in East African hominin archaeological sites.
This technique has been crucial in establishing the timeline of human evolution in regions rich with hominin fossils like the Great Rift Valley.
