You may be right about the Bio minor. The reason I did is because I was only recently listening to an hour long discussion of this on NPR. The guest, an expert in this field, is the one who recommended chemistry because it gets down to the more elemental interactions from which life developed in its earliest forms. He also made the point that life in another location could well be radically different than anything we recognize, hence our knowledge of biology might have little or no relevance.
My opinion? I have none. I know nothing about this field.
