Your question smacks of on of those
“Because there is hydrogen in the universe, there must be water on earth” statements.
Without extensively reading Queller & Strassmann, and being able to discern their claims in context, I have no answer for you, because the statement, as a question, makes no sense.
You criticized the idea that “purpose” is what defines an organism. It was two evolutionary biologists who made the statement. I think you missed that, and was just wondering if you had.
Nothing more.
Think you need to get out more.
