Modelling and hydrodynamics. If locomotion drove evolution in the same way as it seemed to drive the industrial revolution, ignoring the efficiency of an animal's metabolism, these models of marine animals could almost be the real thing.

In the history of science, sperm chemoattraction has long been recorded in a large variety of species, including plants. When a sperm can find an unfertilised egg more easily, sexual selection and a host of other efficient systems improve.

In extreme conditions or even in normal situations, an animal has to get itself back into the groove quickly after any disorientation. Survival normally depends on it. Your sense of place is dependent on either panorama-matching processes or by matching the actual 3D geometry of a place.
