Why do DNS root servers hold entries for two-level names such yahoo.com and purdue.edu, rather than one-level names such as edu and com?

Second-level domain names such as yahoo.com and perdue.edu are not so many in number as to need to be divided between separate com and edu servers. Such a division would bring extra complexity and overheads. Although uk etc. do have separates servers
