I know that mathematics has applications in Biology, and in fact in everywhere, I am curious to know is it happened that a Biological concept comes to help math? I don't mean Biological names be chosen for a mathematical concept like Amoeba! I mean we get an idea to solve or do something or the math question be solved by a Biological method.
As I know there are methods in coding theory that are using Genetic Algorithm which has taken a pattern from actions between genes such as mutation, recombination and resamplaing. I will find a reference and will put it here for you.
You can look at my answer at this link.
