Messianism is concerned with genetic engineering, to a degree. If there is ever to be a decisive shift that puts the human condition to an end, manipulation of genes is likely to play a role - indefinitely extending life span, using DNA samples to resurrect the dead and so on.
The question to consider is the boundary, as regards desire, between the absolute and the merely biological. Humans are innately predisposed to yearn for eye contact, facial recognition and affective attunement - and likewise innately predisposed to seek new horizons. Evolution is a possible explanation for these predispositions, but it may not explain all of them (and we are not able to test the theory, so we don't know). It could well be that one of these innate dispositions is genetic - that is, merely genetic - while the other is a sort of logical, cybernetic byproduct of being an information processing machine (a mind).
At the very least, the cosmic low-level randomness that the theory of evolution depends on (needed for the random mutations that take place between generations) cannot itself be explained by evolution. We can either see it as a will to power, driving species to expand and change, with Nietzsche, or - though though the difference might only be rhetorical - we can imagine that this randomness is a sort of purely mathematical excess.
A major task for thought, then - strangely sci-fi, but totally contemporary and urgent - is to find a criterion for preserving or discarding different parts of the genome. This criterion would presumably have something to do with that which turns out to be cosmic (material) in our nature, rather than merely biological - whatever that turns out to be.
If we could erase the biological predisposition for attachment, the very basis for the human condition at the root of psychoanalysis, should we?
