Question
Define the term ‘Natural Selection’ given by Charles Darwin.
✓
Answer
Charles Darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. He defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
Natural selection is a nature’s phenomenon in which the species which inherits variations and has better chances of survival are allowed to reproduce and produce a large number of off springs.
