I would say true. I say this because there have been times where scientists find out that there are better ways of performing experiments, or found that certain materials work better for certain tasks. (Especially true in medicinal fields!)
Resistor

Hope this helps!
I would say that the most likely environment for these two rock types to be ridge formers would be an arid climate like a desert where there was little water to dissolve. Also, even in a normal temperate environment, dolomite can form a very resistant ridge or cliff former as is the case with the Palliser Formation in Banff Park which forms a pronounced cliff which is very extensive.
Evolution can be defined as the process of the change occurring in a population over a period of time through genetic variation. This genetic variation and the process of natural selection help a species to evolve by selecting the traits that helps it to better adapt to the environment. These genetic variations are inherited over time as the species continue to evolve.
Hence, the correct answer is 'change in population through genetic variation over time'.
