Charles Darwin remembered on International Darwin Day The birth anniversary of renowned naturalist Charles Darwin, born on February 12 in 1809, was celebrated by both historians and scientists across the world. Various institutions arranged special talks on the works and life of Darwin to observe the day. Darwin (1809 - 1882), an English naturalist(प्रकृतिवादी) and geologist(भूविज्ञानी) , is
best known for his contributions to the 'theory of evolution'. According to his theory, all species of life have descended (उतरा) over time from common ancestors(पूर्वजों) and along with another naturalist, Alfred Russel Wallace, he introduced his scientific theory called 'natural selection'.
In his book 'On the Origin of Species', Darwin successfully refuted (का खंडन किया) the earlier concepts of transmutation of species and the scientific community accepted evolution(क्रमागत उन्नति) as a fact and theory of natural selection is regarded as the 'unifying(एकीकृत) theory of the life sciences' which explains the diversity of life. His theory established the principle of evolutionary descent with modification as the most convincing scientific explanation of diversification in nature.
One of Darwin's quotes aptly provides a lesson for human life which goes like this: "It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change."
