And the fact that animals with the exact same genes can be different sizes and have different character traits may be just the first of many things that scientists hope can be learned from these little pigs. 相似文献

I have a turtle. It's very young. It is maybe 1 or 2 years old. Its shell is so hard that it can break my pencil! And there are many stripes (条纹) on its shell. It is very cute. Its nose, eyes and ears are all very small. They look like my pinkie. Its feet are very small, too. Although the turtle is small, it is strong! Its claws are sharp, and they can prick (戳穿) about 5 pieces of paper at once. It can also climb out from a tall vat. It always puts its head, feet and tail into its shell when we touch it. It's interesting. It has no name yet. Can you help me give it a good name? 相似文献
