Though I am almost bald now and has not used comb or hairbrush since last decade at least, but yesterday I thought a lot about hair. I was returning to home from another station by train. It was almost three hours journey. A young girl about 8-9 years and her mother were sitting in front of me. The girl was pretty with her innocent face but the thing that most attracted me was her hair.
She had very long hair, little short from her waist. They were jet black, dense and shiny. They were so beautiful I could not help myself from looking at her again and again.
They descended from the train one station prior to me but I kept thinking about that girl and hair in particular, till my station came.
Theory of evolution says that organisms tend to adopt and improve with circumstances. And, in that process, they slowly discard useless things and develop useful ones. I have no reason to disagree with that either. The premise looks reasonable and can explain many things too. But, when I tried to apply it on human hair, I did not get any satisfactory answer.
Almost all parts of human body have some usefulness. Yes, there are some exceptions like appendix, but human bodies are in the process of losing them. I think that applies even to the hair all over the body too. As humans started covering their bodies, body hair lost their relevance and are in the process of extinction. Human female bodies are ahead in this process. Perhaps, their less exposure to hostile conditions over the time is the reason behind that.
Very recently, a study has been done which tells that even the size of human brain had been decreased by 5% in last 5000 years, because, due to development of helping means over the time, now human brain needs to work less than the past.
But, the question that kept me haunting was, why this theory does not apply on head hair and beard? What is their usefulness after all? Why there is absolutely no change in their status in last 10,000 years, at least?
With love,
Sanjay
