"Interesting" is an opinion. For example, some people think that insects are most interesting, and others may hate them. In my opinion, dolphins are very interesting, but I am equally interested in most vertebrate animals.

No, dolphins did not evolve from men, no other species evolved from men. Dolphins are small whales. The closest land animal to the whale is the hippo. Or at least that is the current theory. So dolphins are more closely related to horses, cows, sheep, and deer than they are to people.
Dolphins in the sea, and dogs on land. They are both very social animals, dolphins in particular.
More interesting means judging what the other guy likes the most and knowing more about it than him and sharing it makes you more interesting.
sometimes but not always ANSWER Dolphins rarely if ever fight with other species of dolphin (with the one exception being Orcinus orca, the killer whale, which may attack dolphins more for sport than as a food source, although this information is anecdotal). Spotted dolphins are not known to be more aggressive than other odontocetes. Check out this website: http://www.acsonline.org
WHAT DO CALL AN ANIMAL THAT LIVES ONLY IN WATER?A ANIWATER
There only true friend is them but they love to play with other dolphins so they have more that 3,0000 friends
I would not say they are not as talented but river dolphins tend to be more shy and not as enthusiastic as sea dolphins. You won't commonly see them jump out of the water and do tricks as you would see other dolphins do.
no
no but they send off sounds sort of like what a bat does. it bounces off the animal and the dolphin knows where the animal is. Get more INFO at www.seaworld.com or www.google.com
There are lots of interesting animals, your question is not complete and cannot be answered.
Dolphins hide in any place available, but they also ram sharks or other enemies, though they usually do this to defend another animal (a relative or human). You can read more on google or anywhere else.
