During the 60's a track was produced known as the Amen, which included a 10 second drum loop. This 10 second drum sample changed the modern music industry for ever, it became one of the most noticable and iconic beats in jungle and drum and bass's history.
Percieved to be the forefather of drum and bass
and its many sub genres. During the 1990's a new scene was becoming popular; Hardcore, breakcore and rave started to appear regularly in clubs.
However the birth of jungle comes from the illegal warehouse parties themselves, where people where into the hyper melodical piano samples and the high pithched voice of which resembles a hypnotic female cartoon vocalist.
However in 1992, two genres broke of from the rave scene (other genres like breakbeat, techstep, etc were also broken down into seperate genres).
These genres were what we know today as jungle and happy hardcore.
jungle usually afflicts itself with ragga, hip-hop and even happy hardcore ( more genres are included however my resources are limited). The Amen break which is basically the ground or basic beat of jungle has been over produced into several different versions, which funnily enough all versions have alot incommon with each other.
It is said by many that drum and bass is slowly taking over most listeners with its more complex and experimental beats, but still, people say that drum and bass is dieing.
This is far from true, like rave , jungle too seperated into different genres and drum and bass looks like the most dominant one.
