Question

What is Darwin's theory of evolution?

Answer 1

Darwin's theory of evolution:

1. The survival of the fittest is Darwin's theory of evolution.
2. The process through which organisms evolve over time as a result of changes in heritable physical or behavioral qualities was first formulated in Darwin's book “On the Origin of Species” in 1859.
3. Natural evolution is described as "survival of the fittest".
4. Darwin studied several species of finches on Galapagos island. He noted that the beak shapes of the birds on each island were different.
5. Though these birds shared a similar ancestor, Darwin reasoned that they had moved to separate islands and hence their beaks had gradually evolved to meet the needs of their respective surroundings.
6. The modification was not caused by the environment directly altering features.
7. Different types of food were accessible to birds migrating to different islands.
8. Those birds with the best beaks for eating the food might survive, reproduce, and pass on these beneficial qualities to the next generation, resulting in a population with comparable peaks.
9. After studying the finches on the Galapagos islands, he formulated the theory of evolution that explains the origin of species.
