Superposition in archaeology and especially in stratification use during excavation is slightly different as the processes involved in laying down archaeological strata are somewhat different from geological processes.Man made intrusions and activity in the archaeological record need not form chronologically from top to bottom or be deformed from the horizontal as natural strata are by equivalent processes.The law of superposition is an axiom that forms one of the bases of the sciences of geology, archaeology, and other fields dealing with geological stratigraphy.In its plainest form, it states that in undeformed stratigraphic sequences, the oldest strata will be at the bottom of the sequence.Part of an organism's DNA is "non-coding DNA" sequences. Some noncoding DNA is transcribed into non-coding RNA molecules, such as transfer RNA, ribosomal RNA, and regulatory RNAs.Other sequences are not transcribed at all, or give rise to RNA of unknown function.

The law was first proposed in the 17th century by the Danish scientist Nicolas Steno.The designation "Transformer" stems from the species' generally-shared ability to transform, to change their bodies at will, rearranging their component parts from a robotic primary mode (usually, but not always, humanoid) into an alternate form; generally vehicles, weapons, machinery, or animals.In some continuities this ability to transform is innate to all members of the species, in others it was a wartime innovation that was adopted by most, but not all, of the populace.This includes animals, plants, protists, archaea and bacteria. This is why children share traits with their parents, such as skin, hair and eye color.DNA is in each cell in the organism and tells cells what proteins to make. The DNA in a person is a combination of the DNA from each of their parents.
