Interpreting the past radiocarbon dating
There is so much in this world that only makes sense in the light of Evolutionary Theory. Some of these layers are from the decomposition of sediment, others come from chemical precipitation, others from decaying organic matter, and others from volcanic lava.The reason we can see the layers is because they were formed in different ways.
Benjamin Franklin saw that there were fossilized sea shells on top of the mountains of Appalachia, some of them imprinted into solid rock, and concluded, “Tis certainly the Wreck of a World we live on!When a species gets split into two groups by a river, mountain range, island, lake, or ocean via earthquakes, floods, droughts, climate change, or continental drift, the two populations will begin to drift genetically.Mutations that reduce an organism’s ability to survive and reproduce will be less likely to end up in offspring.Take a quantity of uranium-238 and in 4.5 billion years half of it will have turned into lead-206.When molten rock hardens into a solid, the uranium-238 within it begins to decay.In 1952 Stanley Miller and Harold Urey synthesized organic compounds from inorganic precursors found in the Earth’s original atmosphere, producing more than 20 different amino acids using electrical sparks to simulate lightning.
Speciation is the process by which new species are formed.

These reasons will work from the general to the specific.
Cynognathus, a Triassic land reptile, fossils are found in South America and Africa.
The Triassic era was between 250,000,000 and 200,000,000 years ago.
By measuring the ratio of carbon-14 in a younger fossil, scientists can estimate its age.
