Temperature Dependent Sex Determination TDS Higher temps = males in croc Higher temps = females in turtles “Hard pressed evolutionists: All this leaves the poor evolutionist in a difficult situation. Whatever arguments that could be fabricated to support one mode of sex determination disintegrates when one considers the other group. Could this whole sex-in-response-totemperature thing have been designed by a Creator with a sense of humor? It seems to me this takes far less faith to accept than some yet-to-be-conceived alleged advantage of allowing temperature to determine sex one way in crocodilians and the opposite way in most, but not all turtles. It really is difficult remaining an evolutionist! I know, for I couldn't do so after looking objectively at the facts. Can you? Should you? “ E. Norbert Smith, Ph. D.

Beware the False Dichotomy of religion vs evolution How could phylogeny explain the difference between turtles and crocs? Would this predict they would be the same or different? ?
