Sex...part two

Post  Admin on Mon Nov 09, 2009 10:40 pm

Sex is a short word, but an immense concept, and many of us spend a lot of time thinking about it. Sex is the engine that drives creation, ensuring propagation of the race and ultimate survival of the species. The imperfection of biological machines means that after a certain period of time they become dysfunctional and obsolescent, and it becomes more economic and energy-efficient to replace them completely than to continue to renew the old ones.

So how can selfish organisms, intent only on their own survival, be persuaded to reproduce and hand on their heritage and their living space to an utterly new individual?

There are a number of instruments, such as the selfish gene theory and the maternal instinct but the chief contrivance is sex, and Mother Nature has been capriciously kind in allowing us this delightful inducement to procreation.

Apart from being great fun, sex allows the mixing of genetic material with its consequent crucial increase in adaptability; no two progeny are exactly alike, as the cocktail of genes will never mix in exactly the same way. This genetic diversity permits adjustment to any environmental changes, as any advantageous characteristics will promote survival and increase their chances of being further propagated. For example, if the weather gets colder, people with a tendency to wear warm pyjamas will be more likely to survive and pass on their cuddly proclivities; thus the human race will tend to become more huggable, and I say go for it
