Rambling thoughts on Darwin’s birthday


I live in Saskatoon (somewhere in Canada) where I have experienced temperatures as low as -450C and I am convinced that this is not the place where nature wanted humans to live: we are invaders from tropics. I am also convinced, from the stories that my parents tell me of my sickness as a child, that I am also not the nature’s favoured one to have seen last 29 winters. A lot of us are surviving today not because of our physical or genetic fitness, but because of mental capabilities of millions of scientists who have been developing medicine, heating/cooling systems, water filters and what not. Clearly, “survival of the fittest” does not apply only to an individual, but to a population that is ready to fight, physically and mentally, the challenges thrown by nature. I am stretching my thoughts and after enough elasticity I ask myself if mental advancement is the real means to long term survival of a race of biological species? Cockroaches have survived more than 300 million years with just about 1,000,000 brain cells in comparison to humans with about 1,000,000,000,000 cells who have been inhabiting this planet for only a fraction of that time.1 (Not to mention Katsaridaphobiafear of cockroaches in humans).

A normal population curve of naturally fit people (fig. 1) would tell us that the proportion of a population that is naturally fit to survive is very small. A large proportion of population falls under the mediocre category; such individuals may survive but are not the favoured ones as they may lack some characteristics that would eventually be their Achilles heel on the day of judgment. The same curve would also tell us that only a very small proportion of our population is smart enough to contribute to our collective wisdom that helps us to develop technologies for human survival. Therefore, we can say that while a very small proportion of population is fit enough to survive on its own, the rest of the humanity is simply riding on the wisdom of very few geniuses. In other harsher words, our human population primarily consists of weaker people like me who would have not survived had it not been for those very few smart guys.

While I was waiting to join my current lab as a PhD student I tried my hand with growing vegetables. What I figured out was that to make Earth produce food is a tough job and my arms were too weak for that. This simply translates to the fact that some of us would have died of hunger had it not been for some unknown farmers who are sweating it out for people like me. Now, I am not a believer of those apocalypse prophesies but I do believe that there will be a time when the fitness of our population will be tested. On that day humans will be pitched against many other species. Competition will be severe. But, I believe that human race will clip_image002survive because of those few fit people. I am already proud of them.
