2. BITS Made Us Do Biology!


I could relate these questions to what is written in prescribed syllabi textbooks of Biology , Maths, Physics and even Economics though I could never use them for fruitful academic purposes (like getting marks), but they did help me with developing an overall understanding of life and its purpose . After all we all living beings are originated from the DNA molecule, the only molecule that can replicate and 'preserve' itself. The property of all livings organisms to reproduce which is also the sole purpose of all living, to preserve its DNA by replication. In the cycle of life- reproduction and death the individual dies but the DNA is preserved by passing it to the offspring, which again does the same thing. Every DNA molecule so produced tries to preserve ‘only’ itself. Over time this caused explosion of new types of DNA molecules (species) but the resources the earth provide are limited  hence competition forced the less ‘survivable’ species to die (natural selection) with every new species trying to survive or in other words every new DNA molecule trying to 'preserve' itself. In such a world where the only rule being Natural Selection a primate was born whose jaw muscles were exceptionally weak due to mutation. This disadvantageous development could not allow it to eat hard nuts but had one more consequence, weak and small jaw muscles occupied less space and it allowed more space for cranium and the brain to grow! That primate was our ancestor who later evolved after a series of other species like Homo erectus (cavemen who discovered fire) into Us!
We Homo sapiens even in this 21st century follow same rule of Natural Selection and compete with each other and try to acquire more wealth. This in our context is not called Natural Selection but Modern Capitalist System.
