difference between epiphany and galeon

Dear sir or madam,

I have a question. What is the difference between Galeon and Epiphany? Does 
Epiphany needs Mozilla to be installed on the system like Galeon does? I use 
Mandrake 10.0 with Gnome and Epiphany and I like that combination. I didn't 
want to play with Galeon (I use to use it) since I have this browser. I hope I 
will get an answer from you. 

Thank you.

Sincerely yours,
Igor Jagec, Croatia
