Second, the animal wasn't 'invented' it was bred, just as most of the animals people eat are bred, humans cannot 'invent' animals. Cows and sheep would not look like they do in the wild, they have been selectively bred for certain traits which humans find useful. I find it hypocritical when anyone who eats meat complains about experiments like this as they are essentially eating the product of the same process. At least these scientists aren't eating the frogs but are instead using them to gain an understanding of biology that can save lives, and doing it in a way that means they won't have to kill the frogs to do so.
