There is a theory that about 50 million years ago, the ancestors of ring-tailed lemurs, flying foxes and other mammals living on the island of Madagascar took a natural "raft" and came to this island in Madagascar in the Indian Ocean. According to this theory, mammals from the southeast of the African continent drifted to Madagascar that year, and the means of transportation they used were large logs or floating vegetation. Before the raft was recorded, the storm dragged them into the sea, driven by the ocean current. These ancient "refugees" drifted for weeks and came to Madagascar. Which of the following, if true, does not support the above drifting theory? ['0 million years ago, the ocean currents around the two continental plates once moved eastward, that is, to Madagascar.', 'Small mammals are naturally slow in metabolism and able to survive for weeks without much food and freshwater.', 'Among the animals that reach Madagascar from the southeast of the African continent, there are no elephants, lions and other overweight and oversized mammals.', '0 million years ago, the distance between the African continent and Madagascar was different than today.']
