Both plants and animals exchange carbon with their environment until they die. A very selective history of life on Earth over the past million years is provided in Figure 8. All rights reserved. This happens at known rates. Measuring carbon in bones or a piece of wood provides an accurate date, but only within a limited range. These methods — some of which are still used today — provide only an approximate spot within a previously established sequence: Although the half-life of some of them are more consistent with the evolutionary worldview of millions to billions of years, the assumptions used in radiometric dating put the results of all radiometric dating methods in doubt.

  1. Although the recognition of fossils goes back hundreds of years, the systematic cataloguing and assignment of relative ages to different organisms from the distant past — paleontology — only dates back to the earliest part of the 19th century.

  2. When scientists first began to compare carbon dating data to data from tree rings, they found carbon dating provided "too-young" estimates of artifact age. Sometimes, only a small part of a fossil is showing.

  3. Over time, the unstable potassium isotope 40K from the rocks decay into a stable isotope of argon 40Ar. In , Danish naturalist Nichlaus Steno put forth the idea that horizontal layers of sedimentary rock represent a time sequence of Earth's geologic history. When the quantities of the parent and daughter isotopes are equal, one half-life has occurred.
