Evolution applies integration of science and related studies.
To you, perhaps. To the faculty where I attended grad school, where part of my study was evolution, fossil man, human osteology, etc., it was not the case. They did not include cosmology and astronomy and the abiogenesis parts of biology in my studies.
Now, this may be a disappointment to you and other creationists, because you seem so sure that evolutions are all trained in these fields, but that we are just lying to you and covering up when we claim otherwise.
You know, one of the problems we have in discussing these matters with you is that so few of you have studied these fields of science. Many of you, perhaps, are in computer related fields. mathematics, or engineering, but so few of you are in the biological, paleontological, and related sciences which deal directly with evolution. As a result, many of you are unaware of the actual course of study which is currently taught.
Try searching online for some college catalogues. I would be very surprised to see astronomy or cosmology in many of the biological or evolutionary science curricula.
