Perhaps the most widely used evidence for the Theory of Evolution through Natural Selection is the fossil record.
The fossil record may be incomplete and may never fully completed, but there are still many clues to evolution and how it happens within the fossil record.
This technique relies on the property of half-life.
Half-life is defined as the time it takes for one half of a radioactive element to decay into a daughter isotope.
As radioactive isotopes of elements decay, they lose their radio activity and become a brand new element known as a daughter isotope.
Understanding the ages of related fossil species helps scientists piece together the evolutionary history of a group of organisms.These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing.As these changes have occurred, organisms have evolved, and remnants of some have been preserved as fossils.One way that helps scientists place fossils into the correct era on the Geologic Time Scale is by using radiometric dating.Also called absolute dating, scientists use the decay of radioactive elements within the fossils or the rocks around the fossils to determine the age of the organism that was preserved.A fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved.
