The 'Origin of Species' is written by
(a) Linnaeus
(b) Darwin
(c) Haeckel
(d) Whittaker
Correct Answer: (b) Darwin
Explanation: The 'Origin of Species' is written by Charles Darwin.
Darwin's Theory of Evolution by Natural Selection is as follows:
1. The organisms with useful traits and higher adaptability will survive. The fittest organism will be able to survive in the world.
2. Naturally selected over-abundance of offspring can lead to a struggle for existence. Organisms with variations can survive and reproduce in an effective manner, producing a large number of offspring with a longer life span.
3. Offspring of survivors inherit the useful variations to the new generation and this variation becomes an inherited feature. Due to the environmental adaptation, the organism with variation adapts and survives in new living conditions.
