Biology is the study of complicated things that have the appearance of having been designed with a purpose.

In biology, nothing is clear, everything is too complicated, everything is a mess, and just when you think you understand something, you peel off a layer and find deeper complications beneath. Nature is anything but simple.

Evolution is cleverer than you are.

Nothing in Biology makes sense, except in the light of evolution.

Biology is the most powerful technology ever created. DNA is software, protein are hardware, cells are factories.
