    @Katja Schulz: Hello, Sorry I did not get back to you sooner but have been very busy. Thank you for your criticisms of the article - I will review it sometime this week I hope and make corrections and improvements. In the meantime I also posted a comprehensive description of the animal kingdom on that page. I would appreciate if you would have a look and offer criticisms of that one too, if you are not busy doing more important things and have the time, Cheers, Jeff Betz
