OK, I will keep my eyes open for that shark - if it is the case, then I find it a little unsettling - as if a natural law has been proven false.

Regarding the natural selection of genes which result in greater longevity, then I would say that there is another factor at play, as well. If grandparents have this longevity gene, and are active and caring in their old age, then in a situation in which this could give their grandchildren an advantage, this gene will be selected for (as their DNA will have been passed on to their offspring and their offspring's offspring).
