Recently some pure Elephant Tortoise re-discovered in Ethiopia. Some pure type pieces remain though most of children are mixed of other type. Scientist is considering to keep pure children before they disappear. Is this a good way of control? I feel this is not natural. What the pure type means. It could be mixture about 1000 year ago. Mixture is a kind of natural evolution and a kind of animal like human should not control the natural change. What I feel is we should not touch them and see what happens in future.
