The way I see it is DNA is much like a very long running program meant to run for millions to billions of years. Our current life is an instance of some code in the DNA. Due to the longevity of the purpose of DNA, and our short span in an instance, it is very, very difficult to ascertain what some parts may be about, or what it's for. Not to mention the high compressibility of information in DNA, some aspects might never really reveal themselves unless met with an instance in an environment it is "meant to run in".
