Then again the question arises, what happened to the dinosaurs and Trilobites and certain other species where we to date find only fossils (but no living relatives remain)?
In general species would adapt over a number of generations, so lowering the temperature for your tropical fish would not work, However, in a larger population of tropical fish with some genetic diversity, if the water temperature was lowered by 1C every generation, no doubt the species would continue to survive.
Originally, trev cited memory as something science cannot explain. Now that he's proven wrong, he back padelled to claimed that the complexity of memory is too complicated to have evolved naturally.
