Entities are known to perpetuate asexually. The need to copulate with another is propelled by a much wider drive acting on more evolved living entities : unity, with entities other than oneself. The need is social. It brings in great complexities for the mind to learn and deal with, much compounding of feelings and emotions, will and thought, and reflection. Vertibrates and higher animals have far more complex sensory network along with mind well endowed to sense, feel and carry the will riding on resultant emotion.
Human beings show a wide range of capability of the mind in different individuals, at different age, under different situations or circumstance. But everyone can choose to put himself through well-laid processes to learn and train oneself into emptying the mind and its hunger. The physical evolution ended a long time ago and the mental one seems to be merely iterating in its well known consequences.
It is almost four thousand years since Buddha pointed out the fact. It will never be that entire humanity takes to his Way. But some who have had their fill of individual living may; and few who are ripened enough to renounce it happily will. The mind is the whole universe of every individual entity. It ceases with cessation of ownership of the universe it contains. The ownership is marked in our emotions, in our will that rides on each. There is no individual entity without it and no mind to accompany such entityship.
There is the immanence and life with its stimulii, and feelings that reflect the immanence in thought, not the individual. Our actions then are acts of life pure, flowing, without desire or memory, even when it seems otherwise !
