Evolution: development of flying not understood (Introduction)

DAVID: Flying is done differently in bats, in birds and in insects indicating it appeared at different times in different ways and represents the concept of 'convergence', which in some minds is another word for design.

dhw: In other minds, convergence simply means that different organisms find similar solutions when faced with similar problems.

DAVID: It should be noted that flying is not a problem unless for some reason it is attempted. The issue is: why attempt it when most animals find enough to eat on land or ocean?

dhw: So what is your answer? Your God preprogrammed/dabbled flight because without it he could not have fulfilled his prime purpose, which was to produce the brain of Homo sapiens? Or could it be that all these organisms found that flight improved their chances of survival?

You keep returning to Darwin and the competition for survival, which is an unproven theory. Balance of nature is a more likely cause.
