Good question. And why, therefore, do evolutionists insist that one cannot possibly understand biology UNLESS one subscribes to evolutionism? No course of study in biological sciences in my personal experience, including at the post-graduate level, depended for its understanding or utilization on an evolutionary framework of interpretation.
So you're claming, for example, you can comparatively analyze gene sequences without an evolutionary framework? Wow. Where did you do you post-graduate work?
What post-graduate level courses did you take? At which Universities?
