i was noticing this morning that there are certain insects on a car that never seem to be disturbed by a motor running, wind convections or any other agitations that an automobile would produce. and add to that the abundance of heat(year round) and food(look at the grill and windscreen) and you have the perfect environment for an insect to thrive. now, these insects aren't big ones. the one i observed was very tiny...like a white gnat, or even smaller than that. i know cars have only been in use for less than a century and that's hardly enough time for something to adapt and evolve...but in a longer period of time, could bugs evolve into what lamprey's are to sharks? co-evolutionary existance with a moveable environment?
