Different phenotypes must exist in equal proportions is NOT one of the conditions that must be met for evolution by natural selection to take place. It depends on the genetic variation in the population.
<h3>Selection, evolution and genetic variation</h3>
Genetic variation is a prerequisite for evolution (and consequently natural selection) to occur.
Genetic variation represents the primary matter for which phenotypes are differentially adapted to the environmental conditions in which individuals live.
This process (natural selection) leads to the differential reproduction and survival of the fittest phenotypes.

Answer:
Biology is the study of life.
Explanation:
Biology is the study of life and living organisms, whether it is plants, animals, or bacteria. It helps you understand you living things function and interact. Advances in biology have helped scientists do things such as develop better medicines and treatments for diseases, understand how a changing environment might affect plants and animals, produce enough food for a growing human population and predict how eating new food or sticking to an exercise regimen might affect our bodies.
It typically slopes down from the base of a steeper retreating desert cliff, or escarpment, but may continue to exist after the mountain has eroded away. it is caused be erosion
