Answer:
separation of populations has led to the evolution of new species
Explanation:
- When the populations evolve to become distinct species, then this process is termed as speciation.
- Speciation can occur due to various reasons and one of these reasons is geographic isolation that leads to separation fo the populations which then faces different evolutionary pressure and thus evolve into new species.
- In the Hawaiin islands, there are different species of honeycreepers because of the unique geology of Hawaii due to which new volcanic islands are constantly being formed and eroded which leads to the separation of population and their evolution into new species.
It was proposed by a scientist named Charles Darwin.

Answer:
It forms from sandstone that has come into contact with deeply buried magmas. Quartzite looks similar to its parent rock. The best way to tell quartzite from sandstone is to break the rocks. Sandstone will shatter into many individual grains of sand while quartzite will break across the grains.
