For almost two years, I've been trying to explore and understand the social situations which have slowly built up the strict roles assigned to the sexes. From the husband trying to bring home the bacon to the housewife packing lunches for their children, it has somehow always struck me as a social conformity rather than a natural state of affairs. But with every bit of new knowledge I gather, I have come to understand that this is merely a snapshot in the life of mankind (womankind too). With all that in context, I bought yet another book on genetics - Adam's Curse.
'To be born woman is to know Although they do not talk of it at school That we must labour to be beautiful.' I said, "It's certain there is no fine thing Since Adam's fall but needs much labouring. -- Adam's Curse, Yeats
We are all born women. Until the sixth week, a foetus is developing identically for both sexes. But why do we men need to exist in the first place ? As it turns out, there are other genes that exist in our cells than the nuclear DNA that we commonly exchange and intermix during reproduction. The reason men exist is because when two normal haploid cells combine, the two cells' mitochondrial DNA end up fighting to their death. Somewhere in the dark distant past, the cells discovered that they could fix this match by depriving one cell of most of the cytoplasm. Those crippled cells, with a few mitochondria churning out O2 free radicals and literally burning themselves up ended up as representative of the male. And they basically fought the system by making up for that in numbers.
But that can't be the only reason to have all the rampaging testosterone fuelled men ? Well, it turns out that the mutation rate is much higher than in the other gamete and it all explodes into randomness. The Y-Chromosome is the only record of this chaos, since it does not recombine with any other and reduce the mutation damage done to it. It is on a slow but sure path to ending up as completely damaged junk DNA.
With the current population and extrapolating the mutation rate over the next 5000 years, the Y-chromosome would have to be exceptionally lucky to survive that many cell divisions. Unless our non-Junk segments of the gene pattern managed to cross over onto some other chromosome,the Adonis Chromosome according to Bryan Skyes, the future of men is a dead end.
We're merely a passing fad.--
<he> Was it good for you ?
<she> Read my blog.
When the month of may dawned, I had promised myself I'd walk 221 kms before the month was through. But 'twas not to be, when I got called home for more than a week and all that energy got channeled out for a different use. But in the last thirty days I've been in Bangalore, I've walked 261 KM. Approximately that is equivalent to walking in to work every day. Over the period, I have gained 4 1/2 kilograms, reintroduced breakfast into my diet and cut down my coffee consumption to just six cups a day.
Take a walk. It will change your life.--
I love walking in the rain, 'cause then no-one knows I'm crying.
