Actually it doesn't. You could talk on the telephone all day and night without wires. You only need wires if you want anyone else to hear you when you speak, or if you want to hear what anyone else has to say. The telephone was invented a long time before radio. By the time radio was first invented, virtually every home in the US was wired to central telephone offices, and it was another long time after that before radio equipment could be made small enough and cheap enough to make radio-based telephoning practical. That only happened within the past 20 years or so ... less than 1/6th the length of time that the telephone has been around.
