Classifying animals e.t.c

[SuperPigeon]

I have been trying to find how life is catergorised in the tree of life with no prevail. I have discovered 7 systems of doing so and I am very confused. Which one (or more) is used today and is the following correct and in order:
Domain - Kingdom - Phylum - Subphylum - Class - Subclass - Order - Suborder - Genus - Species

(more info on the subject would also be greatly helpful)
THANK YOU

Biology, like the sciences in general, is produced by human beings who often disagree with each other's ideas... fancy that... it is sometimes found that some examples within a group can be more or less related than originally thought. Therefore some species are placed in supergroups, for example... This site should be able to help you:

I hope this is what you were looking for... Best of luck!

I always find it amusing that we consider ourselves to be at the top of the evolutionary tree.

Cats - don't work, sleep all day, fed and watered for nothing, if they have a spurt of energy they may go and play with a mouse of two. If they have avoided the removal of the old gonads they may toddle of for some no strings attached amusement with a member of the opposite sex (toms seem to get the best of this deal).

And we live in a totally different world, we worry about everything - about the world, the people in it and our families. We work, we pay for our food and when we get home at the end of the day pusscat is stretching himself after a hard days sleep and looking to be fed something tasty and smelly.

I feel better now - sorry SuperPigeon.
