Guest article by DP Rangan
(The prolific guest writer DP Rangan now writes on the twins in Hindi films, some generic tropes of these films, and gives a selection of songs from some twin films. The highlight of this post is some great songs of the vintage era. This post too has been with me for quite some time. Mr Rangan has been quite understanding of the unavoidable delay in scheduling it. Thank you Mr Rangan for yet another nice post from your pen. – AK)
Four billion years after the formation of the Solar System, the first elementary form of life emerged. Over the next five billion years, life underwent steady transformation and became more and more complex and advanced. Survival of the fittest was the key element in ensuring continuation of species. Apotheosis was emergence of Human beings (Phylum Vertebrata, class Mammalia) as the last to arrive at the scene. There was no longer any need to have large broods of young ones for species continuation among human beings. Single birth was the norm and over a number of years, a human couple, male and female, brought forth several children, and despite partial infant mortality perpetuation of the race was ensured. Still there were odd instances of giving birth to twins, identical or fraternal. Identical were either male or female, while fraternal could be a male and female child. For this post we are concerned only with identical twins.
