The environments that organisms live have unique features and qualities that shape the development of the genetic and phenotypic characteristics of resident organisms to allow them to become suited for life in those regions better. The environment in which species live can be considered a biological and physical environment. These environments vary around the world, and may be hot, cold, arid or moist.Continue Reading
The specific conditions of organisms’ environments leads to the development of certain traits to increase the organisms’ chances of surviving during short and long periods of time in those habitats. Natural selection helps organisms prepare for life in certain area by propagating genes that enhance species’ chances of survival in certain climates.
Natural selection is a biological process that takes place when three specific conditions are met. The first condition required for natural selection is that there is genetic variation among individual species in a population. Additionally, there must be some degree of heredity in those traits, which ensures that specific qualities can be passed down through successive generations.
Variation in traits ultimately affects factors, such as fitness, fecundity, and the ability to mate and survive. Some traits, such as fur coats and thick blubber, help animals survive in cold climates while the ability to conserve water allows species to survive in dry desert regions.Learn more about Environmental Science
