One of the most famous tourist attractions in the State of California is the giant redwood. This redwood might be described as "the tree with the moving foot" because it is not even a native California, believe it or not!These trees, which are among the largest and oldest of all living things, moved to California from the Arctic. Long, long ago they grew in the Arctic, just as enormous and tall as they are today. But the warmer climate drew them southward and it took some seventy-five million years to complete the move.Carried by birds, winds, and some strong-teethed animals, the seeds of the redwood traveled thousands of miles from what is now the northern-most tip of Alaska to California, their last stand.Only the hardest seeds survived—a few that visited Eu- rope soon died out. But those that made it to California put down roots, grew into luxuriant ’forests, and became camera subjects for the hundreds of thousands of tourists who visit California’ s giant redwood each year. How long did it take the redwood seeds to complete their long journey（）
