Proximate vs. ultimate: proximate vs ultimate causation lobsters: navigation via magnetoreceptors (function) allows effective searching (functional) arose by natural selection (ultimate) (posfai et al. Genetics of behaviour rovers vs sitters: for gene (sokolowski 1980) cgmp-dependent kinase rover wins at high population density, sitter wins at low density adult as well as larval behaviour (edelsparre et al.
