Nothing to do with it? lol You can lead a horse to water but can't make him drink. Alright I'm done trying to teach you something. You go on living in your sheltered life of denial. Both links are long papers explaining EXACTLY what is going on. Other species of animals can and do do the same thing. Just look at the research paper on the Tilapia.
Funny how someone who thinks they know so much actually knows so little and refuses to research what they don't know.
Instead of learning something youd rather tell lies and try to put down the one trying to show you something. Oh well. I'll not respond to you any further as it does nothing apparently.

Have a nice life.
