Radiometric dating sediments
It is fine to hypothesize that similarities between different creatures are the result of common ancestry, but since such similarities have been and are often conflicting when compared with other features, it might be prudent to hold back a little when making conclusions about any sort of definite taxonomic classification model or even relationship.The conclusions that are drawn from the evidence are often and have often been very much exaggerated to fit personal beliefs and biases.
No one, not even a scientist, likes to see a theory that has cost a great deal of money and much of one's personal time and effort, go up in smoke.
The importance of the Moon in studying the principles of geology is that it provides an insight into the basic mechanics of planetary evolution and events that occurred early in the solar system.
Much of the knowledge we have of how planets are born and of the events that transpired during the early part of their histories has been gained from studies of the Moon.
Geochronology is the science of determining the age of rocks, fossils, and sediments using signatures inherent in the rocks themselves.
Absolute geochronology can be accomplished through radioactive isotopes, whereas relative geochronology is provided by tools such as palaeomagnetism and stable isotope ratios.

and is now the principal source of information about the absolute age of rocks and other geological features, including the age of fossilized life forms or the age of the Earth itself, and can also be used to date a wide range of natural and man-made materials.
