1) How can something as complex as the human shoulder evolve over an enormous expanse of time and allow survival of a species whose survival is predicated upon the use of a fully functioning shoulder? i.e. How does a species that needs a functioning shoulder in order to use arms and hands (taking out of the equation the necessarily chance evolution of arms, hands, fingers, blood, vessels to transport blood, heart, organs, cartilage, bone, marrow, muscles, joints, cells, and all the things that make up the human body that I have no knowledge of) to build, plow, plant, gather, hunt, hold, nurture, mold, shape, feed and eat survive?
2) Where are the intermediary forms (missing links) in the fossil record? Doesn't it stand to reason that evolving biological life on this planet would leave at least one proven fossil example of partially evolved creatures?
3) Can anyone explain the mind boggling complexity of a single cell and where that cell came from?
These are only a few of my "naive" questions.
