@Ceili,
60 Minutes is a CBS production. I gather CBS is not very conservative, or at least not in the apprehension of those who are in the habit of allowing a few well chosen words to over-ride obvious outward signifiers to the contrary.
As such it is not surprising that it should produce programmes of such a nature which do, of course, reinforce the Darwinian position which I assume it supports for reasons which have been explained earlier in these threads pertaining to this subject.
It might be worth bearing in mind that the Darwinian position is ultra conservative as befits that of a gentleman of leisure, as Mr Darwin was, and who showed ample evidence of being obsessed by repetitive elaborations of easily observed minutiae which I think most psychologists would say was a distraction from the contemplation of his own mental states and the conditions of the workers in the factories from which his life of ease derived.
Your post Ceili betrays a remarkable acceptance of the information seemingly imparted in the programme and which some might say represents the dogma of the scientific priesthood. I presume the usual reverential tones were deployed as is to be expected in such cases as well as the insignias of office of those whose task it was to do so for the entertainment slotted into the gaps between the ads.
