Theory of origin of species by natural selection was given by

Concept -

• Charles Darwin made a sea voyage around the world on a ship named H.M.S. Beagle.
• Charles Robert Darwin gave the theory of evolution by natural selection.
• The theory was known as the theory of natural selection.
• He explained the process by which organisms change over time as a result of changes in behavioural traits.
• He proposed this theory in his book “The Origin of Species”.
• He gave an explanation of the formation of new species i.e. various species evolve from single species through adaptation to the environment.
• He is also known as the father of evolution.

Explanation-

• Darwin explained that variations appearing due to environmental changes are transmitted to the next generation.
• So offspring become different from ancestors.
• In the next-generation process of Natural selection repeats so after many generations, a new species is formed.

Therefore the theory of the origin of species by natural selection was given by Charles Darwin.
