The answer is a process that selects variation that help survival and that spreads the variation to more offsprings.

The idea is that there is a higher chance of survival if the organisms has certain characteristics and it is more likely to pass on their genes of this characteristic to the next generations.

For example, there's dark colored fish and white fish. In the deep ocean, dark colored fish can camouflage themselves. However, white fish can be seen easily by predators. Therefore, eventually more dark colored fish survives and more offsprings are dark ones.

Construction of a solar power tower in the California Desert will threaten the existence of Desert torties, mountain yellow legged frog and and Joshua tree.

Explanation: The construction of solar power towers in Mojave desert in California poses a threat to the existence of quite a number of plants.The Mojave desert houses the largest solar power plant in the world,creating the solar power tower will create job opportunities for people but at the same time endangering the existence of about 12 rare plants that are found in the region of which Desert torties, mountain yellow legged frog and Joshua tree are greatly included,these plants cannot co-exist with solar thermal mirror arrays,this brings a controversy between energy/electricity generation and wildlife/ecosystem conservation.
