Deduce the approximate age of materials based on a simple decay curve for a radioisotope. Describe the major anatomical Dating rocks and fossils using radioisotopes that define humans as primates. Outline the trends illustrated by the fossils of Ardipithecus ramidus, Australopithecus including A.

State that, at various stages in hominid evolution, several species may have coexisted. Discuss the incompleteness of the fossil record and the resulting uncertainties about human evolution. Discuss the correlation between the change in diet and increase in brain size during hominid evolution. Distinguish between genetic and cultural evolution. Discuss the relative importance of genetic and cultural evolution in the recent evolution of humans.

Version of an element with a different number of neutrons from the usual version of the same element. Isotopes that release some of their subatomic particles to reach stability. Radiation is not harmful to us but can be measured in the lab. What is the approximate age? Half-life is the amount of time it takes for half of the radioactive isotopes in a substance Dating rocks and fossils using radioisotopes decay. Grasp objects very important for climbing.

These radioactive isotopes are unstable, decaying over time.
