Evolution Theory: Charles Darwin's Natural Selection

Charles Darwin = English naturalist who proposed natural selection Theory of Evolution = Proposed by Charles Darwin On the Origin of Species = Book published by Charles Darwin in 1859 Natural Selection = Process where organisms with beneficial traits survive

Species produce large number of offspring = Part of Darwin's theory of natural selection Limited resources in nature = Factor leading to competition among organisms Survival of organisms with beneficial traits = Result of adaptation to environmental stress Population becoming better adapted over time = Outcome of evolution process

No two individuals are exactly alike = Diversity within a species Traits distributed by chance = Random inheritance of traits Survived organisms inherit beneficial traits = Natural selection principle Gradual adaptation to environment = Evolutionary process
