Actually, lots of circuits can be built with components specified to within 20%, perhaps with some key components specified more tightly. Good designs are robust against component variation.

And one of the mechanisms for making robust designs is feedback (think 98% of op-amp circuits), which happens to be a favorite in biological systems.

Agreed, got my degree in BME and it was probably evenly split between Bio, EE and Mech E. Went on to work in industrial automation, which a lot of people look at me with a questionable stare, but actually makes perfect sense.

I remember going to a career fair senior year right after doing a physio lab where we directly studied feedback systems. The company I ended up working for was demoing their software, which was control graphics. Looked a lot like the diagrams we were using in labs.
