The modern concept proposes the Adamu (Adam) was comprised of, initially, both genders
From ‘The dictionary of all Scripture and Myths.’ The Kabbala describes four Adams, the two highest of which are celestial and spiritual.
The third Adam is the terrestrial Adam, made of ‘dust,’ and placed in the Garden of Eden. This Adam was an androgene . . . . . It had, when first created a glorious simulacrum, or light body, and answers to the Yetzeeratic World, ---- Ibid., p. 418.
The fourth Adam was the Third Adam as he was after the fall, when he was clothed with animal skin, flesh and nerves, etc. This answers to the lower Nephesh and Guff, i.e. body, united. He has the power of reproduction and continuance of species, and also answers to the Aseeyatic world, but in him is some of the light of all the preceding (Adams) ----- ibid., p. 418.
