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

According to Charles Darwin, the Theory of Evolution is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. These changes were brought about to allow organisms to adapt to its environment and survive and produce offspring.

The law of superposition supports the theory because it is a basic law that states that in any undisturbed sequence of rock deposits, the oldest strata is always at the bottom. And as the layer goes up, the younger the age of any discovered fossil is. 

The geologic timescale supports the theory because it is a chronological dating system wherein the timing and the relationship of events that occurred in a specific place is described and connected to Earth's history.

Fossils are proofs that there are organisms that lived before us. The conditions where fossils are found are also linked to their conditions at the time they were still alive. Changes in the area can be studied and observed to predict why and how fossils lived and died.
