That isn't fair at all. All adaptations are ways of dealing with
problems. A seagull has the problem of getting enough fresh water to
drink, which it solves by drinking sea water and excreting the salt. A
mammal or bird has the problem of keeping thier metabolically produced
heat in thier body, which they solved by evolving hair and integument
feathers. Elephants are big animals that like in hot environments and
build up metabolically and solar produced heat, which they dump (in
part) through thier big ears. A sauropods were huge animals that
built up metabolically and solarly produced heat, and got rid of it by....we
don't know. That was the question. Yes, obviously they dealt with the
problemsomehow, but HOW? Just saying they existed doesn't make the
problems magically go away. Your response did not address the question, or
the problems involved.
Modern animals have adaptations that allow them to get around the
problems and dangers of thier day to day existence. All this discussion
was about was HOW sauropods dealt with the problem of heat buildup.
Your attitude is similar to the one that cropped up with the T.rex
debate. I think there is a common tendancy to forget that dinosaurs were
animals with the same difficulties as modern animals in maintaining
homeostasis and coping with annoying biological, thermodynamic, and mechanical
concerns and limitations. They obviously dealt with these problems SOMEHOW:
figuring out HOW is to a large degree what paleontology and the study of
evolution is all about.
