Early life probably resembled today's prokaryotic cells, meaning the DNA was in a chromosome that was large and circular.  But today many forms of life have divided up their DNA into many linear chromosomes.  Linear chromosomes introduce a problem of "losing" ends in the replication process, and I can't think of an advantage. 

Was this just random chance that so many cells now have their DNA in many, linear chromosomes, or is there some advantage over a circular chromosome?

This is just a complete guess, but it might have something to do with there being less 'tangling' during replication etc.
