Darwin

So organisms in terms of organs, either use or loose them over time. Which is an interesting prospect, which accounts for the fact that humans no longer have a prominent tale (although some do in the odd case). But I have to pose a couple of questions, or at least reiterate the problems that Darwin himself says "I can never reflect on them without being staggered."
The lack of transitional species, I mean, the missing link between apes and humans, is still missing. Perhaps this can be attribed to the incomplete fossil record, but will the fossil record ever be complete? The fact that different species when interbred produce offspring that are sterile. Like when you mix horses and donkeys, and they make sterile mules. That is a difficult hurdle to over come but if the process of natural selection is over a vast period of time, then this problem would not necessarily be a factor becuase the populations would not be depend on each other enogh where producing sterile offspring would hinder the natural selection process. These issues that Darwin brings are not entirely crippling to the theory, but they are definite issues.

Another question: since we have been taught this theory considerable unquetioned throughout grade school, does our history of knowledge in some regard change our outlook on Darwin's theory of evolution through natural selection and mutation.
