The increase in dark-colored individuals in a population is often attributed to natural selection, particularly in response to environmental changes. For example, during the Industrial Revolution, darker moths became more prevalent in polluted areas because they were better camouflaged against predators than their lighter counterparts. This selective pressure favored the survival and reproduction of dark-colored individuals, leading to an increase in their frequency in the population.

What has caused the theory of natural selection to change over time?
Better evidence, especially from genetics. When Charles Darwin first proposed the theory of evolution by natural selection his mechanism of heredity was dead wrong. He posited a blending type of heredity. When Gregor Mendel's work was rediscovered in about 1900 particulate inheritance was brought to the forefront of evolutionary thinking and the synthesis of the 1930's and '40's cooperated this thinking with Darwinian though to give us modern evolutionary theory.
Which process in the water cycle is caused by an increase in temperature?
Evaporation is the process in the water cycle that is caused by an increase in temperature. When water temperatures rise, water molecules gain energy and turn into water vapor, which then rises into the atmosphere forming clouds.
What skin disease is caused by increase mitotic division of epidermal cells?
Psoriasis
An increase in evaporation is caused by?
An increase in evaporation is caused by higher temperatures, increased surface area of water bodies, and higher wind speeds. These factors provide more energy for water molecules to overcome attractive forces and transition from liquid to vapor state.
Which planet is next to Earth but is rust colored?
The planet next to Earth that is rust-colored is Mars. Mars gets its reddish appearance from iron oxide (rust) on its surface.
