Species are more the result of tinkering than perfection
Summary
Quotes
« François Jacob once described evolution as "bricolage", and he was right. When we contemplate the living world, we get the impression that everything works perfectly, that "all is for the best in the best of worlds", to quote Voltaire once again. Closer observation shows us just how right Jacob was. Animal anatomy is not so "well done". The famous aortic arch that sometimes causes us so much trouble is a heresy. The path of the aorta is indeed a heresy for any sensible engineer. »
