Who observed that plants and animals change over time in order to survive

Charles Darwin observed that plants and animals change over time to survive.

Explanation:

His full name is Charles Robert Darwin. He went on a Voyage in H.M.S Beagle, a Royal Navy Ship for 5 years. He published that the distribution of animals and adaptation are the result of geographical location. He published his findings in a book named ‘Origin of Species’.

He gave the principle of natural selection as the driving force of evolution. The survival of the fittest is the principle in which animals that have beneficial modified structures have a greater chance of survivability. Charles Darwin was fascinated by Galapagos Island.
