This is a method of "inferring the divergence of time of clades from a common ancestor by means of gene/protein sequencing" and has been termed 'molecular dating'. The process is one in which there is a

If the temperature is taken miles away, or if the insect that was found and studied was not exactly the same as one that had been studied before, only similar perhaps, the defense attorney will also often argue that the entomologist's testimony is only guesswork, and therefore that it is not valid and should not be admitted as evidence (Sachs, 1998).

In Paleontology, however, these wing digits have been considered as digits 1, 2 and 3 based on phylogenetic assessment of the fossil lineage suggesting that birds have evolved from theropod ancestors that had lost the fourth and fifth digits. Critics of this theory have suggested that birds have evolved from some other ancestors that had lost the first and fifth digits. Studies of developing limbs of chicken, including a

Defined so, evolution can refer to any phenomena-- evolution of universe, evolution of human culture etc. -- that change over a period of time. However, in common parlance, evolution refers to
