24 Nov : Now that’s called Evolution – From 1859 – till date

It’s a great feeling to see your kid growing day by day. His cute little hands convert into solid palms and his small footsteps lead to long and difficult journeys of life. They even resemble their parents in one or the other way. Sometimes we even relate a child to his/her grandparents or great grandparents and so on. That’s truth for all living organism.
This is called Evolution.
The theory of evolution was given by Charles Darwin.


It is called ‘Theory of Evolution by Natural Selection’. It was first formulated in Darwin’s book “On The Origin of Species” in 1859. It is the process by which organisms change over time as a result of changes in heritable physical or behavioural traits.

The theory is the widely held notion that all life is related and has descended from a common ancestor: the birds and the bananas, the fishes and the flowers – all related.

1859 में आज ही के दिन ब्रिटिश वैज्ञानिक Charles Darwin ने Evolution Theory यानी किसी भी जीव के विकसित होने की पूरी प्रक्रिया के बारे में अपना शोध दुनिया के सामने रखा था। इस शोध को उन्होंने ‘on the Origin of species’ नाम से प्रकाशित किया था। इसे evolutionary biology की आधारशिला माना जाता है। Darwin की इस theory के ज़रिये दुनिया को ये पता चला था कि जीवों के शरीर में वातावरण और परिस्थितियों के आधार पर काम करने के लिए धीरे धीरे परिवर्तन होता है।
