If you look at how bikes have developed over the years, hybrids are essentially long-wheelbase traditional steel 27"/700c road bikes with fairly relaxed geometry and enough frame clearance to allow decent width tyres and mudguards.
MTB's, in their original fully-rigid format, evolved from 26" wide-tyred US utility type frames minus the mudguards and anything else that was not deemed essential and so could be left off.
Until the advent of oversized tubing for bike frames, pretty much every bike built to Inch standards, employed a frame with a 1" diameter top tube and 1 1/8" diameter seat and down tubes, irrespective of it's geometry and intended use. If you look at a conventional horizontal top tube "hybrid" frame, such as a Raleigh Pioneer, there is no significant difference between it's silhouette, and that of any number of non-racing, general purpose drop bar club riding or touring bikes. A 700c hybrid frame could easily be fitted with drop bars and ultra-light wheels and drivetrain components and you'd end up with - a lightweight road bike, with maybe a little extra BB height clearance.
