Some believers in evolution argue that humanity has declined or devolved by not maintaining the precepts of “survival of the fittest” and actually nurturing the sick. So it appears that uncomfortable data is either dismissed or creates new hypotheses in such people but they never question their basis which is “does God therefore exist?”
Yes … there are some die hard believers of evolution who hold that “fitness” determines who will survive and who will not. They present examples of weak animals being allowed to die off and elderly being neglected and so on.
However, humans demonstrates abilities that oppose this and additionally we consider these things the height of humanity which is to protect the weak and nurture the elder. This attitude of the evolutionary atiests are hell bent for selfishness and pseudo-promote the ethos of ‘uncaring’ … when it is in their favour they use the arguments of mothers caring for the young, but at other times the rules are not always followed.
Some people however, argue that it could still be survival of the fittest through preservation of wisdom and experience can make us better … but this is the philosophical endeavours and today we believe that we are more intelligent than people of yesteryear so one of these positions must be an evolutionary regression rather than a progression. They get themselves in a twist when they hold too fast to the “survival of the fittest” rule especially when applied to humans.
