Dating layers with no ages
Pierre-Louis Maupertuis (1698-1759) published a book in 1751 in which he concluded that new species resulted from the recombining of different parts of living animals.
These rocks normally form relatively horizontal, parallel layers, with younger layers forming on top.
Both 10Be and 36Cl are formed as charged ions in the ionosphere.
Thus each annual layer starts 10Be and 36Cl poor, becomes 10Be and 36Cl rich, and then becomes poor again. Although what is said above is true, this is an exceedingly minor effect.
He wrote about there only being a few kinds of creatures to start with and that these multiplied into many kinds over time.
Benoit de Maillet (1656-1738) wrote that fish had become birds, mammals and men.
