Genetic sex is an evolutionary stratagem whereby innovation is distributed. It is an accelerated and flexible method of maximizing evolutionary potential. Modifications of gene structures are trialled in the so-called 'phenotypes' where the physical biological entity benefits or not from the changes. If the modification makes the individual more 'intelligent', in the sense of being able to avoid being predated before itself participating in sex, then the innovation enhances its prospects of survival in the gene pool. The distribution of detrimental changes is restricted by the lack of survival success of the individuals receiving the changes. The distribution of advantageous changes is enhanced by the increased success of the individuals receiving them. In a relatively few generations, advantageous multiple changes are quickly made available to the whole gene pool in those species which utilize sexual reproduction. Their survival intelligence is accelerated in the predator-prey arms-race, and with barely an exception, the alternative asexual strategies for reproduction have resulted in the species becoming extinct.

From a cultural perspective, the sexual equipment that individuals inherit, and the inclinations and instructions that come with it, are both often ill-defined. Many individuals are entirely unconcerned that the evolutionary function of the device is that of procreation. Diverse inputs into the development of the sexual polarity of an individual are not always coordinated enough to achieve the heterosexual behaviour which is facilitating the evolutionary process. Hormones which influence the foetus during and after birth, acquired learned concepts and imposed cultural imperatives, are all frequently biologically incongruent.

The biological purpose of a phenotype is to be a procreation facilitator. The perspective that humans are educated to appreciate, is that a particular living creature is an entity which consists of an intricate interrelationship of functioning organs and structures, of which one or more of them happens to be organs for reproduction. Biologically however, the entire organism is merely an intricate device for species continuity, and whilst this is reasonably obvious of course, in the case of humans it is usually entirely ignored. Much human behaviour is readily explicable if one adopts the perspective that a human individual is a purpose built sexual facilitator, and that its entire biological purpose is that of seeking and finding other sexual entities. Many advanced chromosome seed banks have evolved biological forms with arms and legs to foster locomotion, nervous systems to develop environmental awareness, and digestive systems to extend longevity, so that the sexual reproductive mechanisms will have their operational program opportunities considerably enhanced.

In order to facilitate its various designs, sex was obliged to invent advertising. The reciprocal duality aspect of most sexuality systems is the evolutionary basis of the phenomenon whereby one of the participants demands an increasingly bizarre range of advertising forms and behaviours from a prospective mate, before any copulation-type performance is attempted. Thus it is that tail feathers must be perfectly irresistible, the scars of successful herd dominance must be prominent, the shape of the body must conform to contemporary standards of fashion, and the physical size of the apparatus being presented should err on the impressive side of adequate. Chemical advertising in particular has proved exceedingly successful in facilitating the opportunities for available sexual aspirants. Female moth pheromones are virtually homoeopathic in their potency. Mantidae sense out the potential for making little mantes. Heterosexual humans mutually respond to one anothers scent envelope, and discharge their hormonal imperative to make more scented taxpayers, while fancifully talking of love at first sight. In certain locations, a bedizened display of costumery, lotions and decorations... advertising any proportion of bisexuality whatever... will successfully attract an astounding variety of night-life.

As an observable physical activity, sex is the operational deployment of any biological structure or system, which has functionally evolved for the intention of delivering gametes to a suitable development site. In the garden, such activity is on-going and essential for success of the curator. Humans in general however, don't normally indulge in sexually motivated behaviour as a means of ensuring that their garden flourishes, but rather to ensure their equipment doesn't become rusty. They have developed a resourceful and ingenious support system for any possible maintainance and servicing that their creativity can possibly devise. No matter what particular individuals are inclined to do with their apparatus, consultants are readily available to monitor and oversee all aspects of the procedure.
