What to do 'till Evolution arrives If the force behind change is the need of some new feature for survival, how did great, great grandpa survive while waiting on the eons of the time to pass so evolution could cause change? Intermediary Survival Sea spider builds her home under water but has to have air. It carries air down to the nest on specialized abdomen and traps air in its nest. Food is from ocean floor. How did the spider make the transition from land to sea? At what point did she become able to live under water - half way? the need of some new feature for survival This is one of the great misconceptions of evolutionary theory. The great-grandpa cannot know what characteristic to look for or pass on to ensure the grandchild's survival (Especially before there were self-aware creatures). The grandpa merely survives and has children. If those children happen to have a characteristic that becomes essential later, then they will survive while all those grandchildren who didn't have the characteristic will not. It's not a matter of anticipation, the creature is either already able to survive or it will die. If none in the species are able to survive it then the species will become exctinct. One reason life on earth seems so perfectly adapted if because it is made up of the survivers. There are billions and billions of creatures who left no offspring and they represent the great group who was less than well adapted. Sea Spider? I don't know this particular case history. It does not seem hard for an insect (or arachnid) to carry a ball of air clinging to it when going under water. If this saved them from being eaten by birds while other spiders were eaten, then the practice would become more common. It may have started with spiders who "ducked and hid" when birds were around with air trapped to their hairy bellies. (The spider story is an example of a Just So story (after the Rudyard Kipling books i.e. how the leapord got it's spots). As I said I'm don't know much about that spider so I really shouldn't be making up stories about how it evolved with no evidence. TP
