For example, "Why" and "how" do birds fly? They fly, in part, to escape predators on the ground. They fly to reach different feeding areas as the seasons change. For all we know, they may also fly just for the fun of it. Ever notice the birds that dive in front of your car at times?
Biological evolution can explain the development of feathers, the ancestry of feathered dinosaurs from the Cretaceous era and the development of characteristics needed for flight. It cannot answer and never proposes to answer the question of, "Why do birds and their ground based ancestors even exist at all?"

I like the feather example. It is with faith we accept that DNA changes were made and created the very first feathers.

If so, it would not be at all difficult to imagine how scales could have evolved into feathers by only a small genetic change. However, common sense shows the huge flaw in this ...

Ooops. New structures, new DNA and new proteins. Feathers are very complex structures under a microscope.
Adaption requires a lot of faith.

According to an ABC News article1 reporting on the July 14th issue of Science magazine,2 the beaks of Darwin’s finches in the Galapagos Islands have “evolved” yet again. Peter and Rosemary Grant, who have done extensive research on the birds for many years, have found that the medium ground finch now has a smaller beak. They observed that this occurred in a very short timeframe.

short time frame? 30 minutes?
