However, human beings love to see factual precision, and we want to know how old something is.
Please remember that all dating methods, even those termed "absolute," are subject to margins of error. That is a very small amount of possible error range. Modern studies almost always use two or more methods to confirm dating work and to build confidence in the results obtained.
The earliest hominin, of presumably primitive bipedalism, is considered to be either Sahelanthropus or Orrorin, both of which arose some 6 to 7 million years ago.
The non-bipedal knuckle-walkers, the gorilla and chimpanzee, diverged from the hominin line over a period covering the same time, so either of Sahelanthropus or Orrorin may be our last shared ancestor. The early bipeds eventually evolved into the australopithecines and still later into the genus Homo.
Basis of Radiocarbon Dating Problems with Radiocarbon Dating The Earth's Magnetic Field Table 1 Effect of Increasing Earth's Magnetic Field Removal of Carbon From the Biosphere Water Vapour Canopy Effect on Radiocarbon Dating Figure 1 Apparent Radiocarbon Dates Heartwood and Frozen Time Early Post-Flood Trees Appendix Radiocarbon Date Table HOW ACCURATE IS RADIOCARBON DATING? The normal carbon atom has six protons and six neutrons in its nucleus, giving a total atomic mass of 12.
Radiocarbon dating is frequently used to date ancient human settlements or tools. It is a stable atom that will not change its atomic mass under normal circumstances.
This collision is less destructive than the initial collision that produced them.
The radioactive carbon has six protons and eight neutrons in its nucleus, giving it a total atomic mass of 14.
This atom is not stable, and will break down, releasing nuclear energy in the process.
Dating is not necessary to demonstrate that evolution is a fact.
Chronological sequence is all that is really required.
