The ONLY purpose of the article is to try to set in human’s minds that we humans can just as easily change our sex - “see, look at how nature says sex change is possible”.
No doubt about that!
True ,that is the reason for this article.
It’s the same reason why there have been articles about gay penguins, or other evidence of homosexual behavior in the animal world. It’s all supposed to tell us that these behaviors are natural among various animal species.
