Eli and the Angler Fish.

My grandson, Eli, is now eleven years old and has progressed from "Why?", "When?' and "Where?" to "Who?" and "How does it work?"

He tuned into  a debate on evolution last week and was able to follow with keen attention the contrasting arguments of "Creationism" and "Gradualism by natural selection."
What was of great interest to Eli was the case of the angler fish.
I have enclosed a picture of the little beauty.
The discrepancy that Eli pointed out, was to do with the rod and the worm on the fish's nose. Just how did that fish survive while it was growing a worm on the end of the rod? Basically it would be fishing  without bait for a million or so years until the worm evolved.
Well, if an eleven year old can ask questions like that, why can't a seventy year old  biology professor?
I guess the answer to that question is not about the worm on the end of a fish's nose but about the brain in a man's head!

Jubilate.
