time scale and determine if a certain specie
evolved from another specie. Radioactive dating is the best method for
determining the age of rocks and fossils on a scale of absolute time. All fossils
contain isotopes of elements that accumulated in the organisms when they were
alive. By determining an isotope's half-life which is the number of years it takes
for 50% of the original sample to decay, it is possible to determine the fossil's
age.
