Church president Gordon B. Hinckley says that the Church only requires belief "that Adam was the first man of what we would call the human race."
Gordon H. Hinckley, "The Origin of Man" (2002), in Jeffrey M. Bradshaw, "LDS statements on evolution and the origin of man," Science and Mormonism: Cosmos, Earth, and Man, ed. David H.

What the Church requires is only belief “that Adam was the first man of what we would call the human race,” says Gordon Hinckley, the church’s living prophet. Scientists can speculate on the rest, he says, recalling his own study of anthropology and geology: “Studied all about it. Didn’t worry me then. Doesn’t worry me now.”
