Sweat glands, and mammary glands, which are modified sweat glands, are unique structures peculiar to mammals. The evolution model of origins predicts that there will be an upward, irreversible development of both sweat glands and mammary glands as one goes up the ladder of mammalian development. Observations reveal, however, that there is an up-and-down variation of complexity of sweat glands among the orders of mammalia. Gaps are evident, as sweat glands are absent in two orders, Proboscidea and Rodentia. With regard to mammary glands, there is not a smooth downward loss of teat number among orders of mammals as sheep, horse and elephant all have a single pair of teats just as man. These data correlate nicely with the prediction of the creation model: that the Creator did not follow the mode of evolutionary development but rather made different provisions of sweat glands and mammary glands in different animals of the class, mammalia, in order to serve His specific purposes.
