Detailed explanation-1: -The theory of evolution is based on the idea that all species? are related and gradually change over time. Evolution relies on there being genetic variation? in a population which affects the physical characteristics (phenotype) of an organism.
Detailed explanation-2: -Gradualism in biology and geology refers most broadly to a theory that changes of organic life and of the Earth itself occur through gradual increments, and often that transitions between different states are more or less continual and slow rather than periodic and rapid.
