In this method heritable traits that help organisms to survive and reproduce become more common in a population over time.ĭarwin’s theory points out that the life of living organisms is related and has descendants from a common ancestor like birds and bananas, fishes, and flowers all are related. He also suggested a mechanism for evolution and that is natural selection. In it, he told that species evolved and all living things can trace their descent to a common ancestor. ![]() As we know that Darwin wrote the book Origin of Species.

It is explained that organisms change over time as a result of changes in heritable physical or behavioural traits. Let us tell you that the theory of evolution by natural selection was first formulated in Darwin's book "On the Origin of Species" in 1859. He continued his work and the trip led to groundbreaking scientific discoveries. On the trip, he collected several samples of plants, animals, rocks, and fossils. There only he found how life is unique before returning to London. The diversity that is seen in the animal and plant kingdom occurs due to natural selection, migration, extinction, and genetic mutations.Ĭharles Darwin visited the Galapagos Islands and grasped the significance of unique wildlife. His book named "The Origins of Species" was published in 1859, where he argued that all present-day life forms on Earth came from a single ancestor. He revolutionaised the field of natural history from his theory of natural selection. Every year on 12 February Darwin Day is celebrated to mark the birth anniversary of Charles Darwin. ![]()
