There’s no major math involved.

There's no math involved in the creation of receptors that receive and interpret electromagnetic waves based on their frequencies? Do you have any idea how absurd that assertion is?

There's no major math involved.

When a stone is dropped from a height, and in doing so, seeks the ground, is any major math inherently involved, other than natural physics? Is there any inherent intelligence within the stone, to guide its mass to the ground?

Same way, with electromagnetic radiation falling on structures on the organism, that causes electrical signals to arise from the energy interactions. The "math" acceptable is determined by repeated testing of survivability and utility.

How much "math" and complex calculus did you study at age 4 when you learned to catch that ball you used to play with?
