The birth of Hip-Hop was a combination of a number of things happening at the same time. The invention of the Tuntable and the sampler as well as MC's and radical poets combining.
DJ's Like Grandmaster Flash would take the best parts of funk, soul, blues, rock records and make complete tracks used short sections. The DJ's mainly used funk records and sections from Drum Breaks. The use of the "breaks" would form the basis for the rhythm in Hip-Hop. MC's would join DJ's to provide extra interest and an extra rhythmic demention to the music.
