As morally wrong as it is for human relatives to have sex/reproduce with one another, why is it a bad idea in physiological terms, in particular brother and sister relations?

Does it have something to do with them both sharing the same DNA etc? I've heard of possible physical deformaties and mental problems e.g. retardation etc..

Do any other species have these problems, like say feral cats who tend to cluster in groups and produce many offspring that live together?

And no, for you sicko's im not thinking about doing any of the sort.. I'm just wondering.

Thanks!

You now like certain hormones or chemicals that our body releases (im not entirely sure about this but isnt our body suposed to like produce different chemicals for like say anger, love, excitement?). Like say a person who reacts angrily alot his or her brain prefers the chemical of anger or the part of the body that releases it sort of creates more of the chemical.

On a side note; not to be gross, but why can't you fertilize your lawn with your own poo? Not that I would do that, but it seems weird that our waste has to be treated at a plant, but animal waste can be composted and used effectively? Maybe a farmer can answer me this....

A starfish can grow a new arm, but you or I cannot? A salamander can regenerate a severed leg, but humans have to use manufactured prosthetic legs? The planarians (flat worms) can be cut into 50 pieces and you will end up with 50 smaller worms. If an arm of a starfish is cut off, you will have two starfish after regeneration and crickets can regenerate their legs.

These are just a few examples of creatures capable of regenerating complex structures of limbs and being able to do this repeatedly! So why do we humans not have this ability? Better phrased, what do they have that allows them to do this that we apparently do not?

I would like to get the biological / anatomical answer if you know it please. Thanks!
