Yes. It's the same one as post #5. They brought the 'memory' with them when they migrated from Sundaland. Out in the pacific and SE Asia there are many stories/legends similar to those told in our Christian Bible, etc. For example, Cain and Abel are named Manup & Kulabob. See here.
"Chapter 16 -- Cain and Abel -- Shepherds or farmers? - Who was the hero, Cain or Abel? - Are Cain and Abel motifs related to the Adonis/Attis/Osiris type? - Sumerian parallels - An eastern origin of the two-brothers conflict - The two warring brothers in Maluku and Melanesia - Kulabob and Manup - Kulabob and Manup: the core story - Pale-skinned brothers from the West? - the start of the odyssey - Episode 1: Kilibob leaves Madang - Episode 2: leatherskins, trevally and kingfish - Episode 3: Mala's travels on Umboi - Episode 4: Ambogim - Episode 5: The tree of wealth and plenty - Episode 6: Namor's Ark - History or myth? - Two brothers in the Sepik- Basin? - Two brothers spread east to the Pacific Epilogue -- Filling in the gaps - The trail West - Problems with dates of migration - Some stories can be dated - Just what did the East teach the West?
Just goes to show that all over the world in all cultures there have been dysfunctional families with warring brothers.
Fortunately, I know my younger half brother has no designs upon my crown, even though he will inheirit nothing.
