How do the law of superposition and geologic timescale support the theory of evolution?

The law of superposition clearly states that in any uninterrupted concatenation of rocks, the bottom-most layer is the oldest. By observing the ascending layers of fossils, the archaeologists can determine how the evolution took place. The geological timescale works on the same principle.

Explanation:

The law of superposition helps the archaeologists in determining the order in which the evolutionary events may have occurred. The geological timescale is a method applied to determine when in the history of time must have an event occurred. Thus both, the law of superposition and geological timescale support the theory of evolution in a similar way.
