    I have always had the doubt that which type of cells evolved first,the prokaryotes or eukaryotes...although many people favour that prokaryotes came first..i would like to know your opinions..support your opinion with proper reason/logic.

    Prokaryotes came first. There are all kinds of reasons for being pretty confident of this; the simplest is that eukaryotes do not have as long a fossil record. They also appear to nest within the prokaryotes in evolutionary relationships.
