**Abstract**

Adaptive evolution implies evolutionary shifts within an organism which make it suitable and adaptable for its environment. Genetic resources of sago palm (*Metroxylon sagu* Rottb.) populations in Indonesia were explicated as follows: (1) Characters of sago palm in Indonesia were shown varied based on cpDNA markers and large variation based on RAPD markers. (2) Variation of starch production of sago palm correlated with *Wx* genes variation, (3) Distances barrier and geographies isolation in line of sago palm dispersions in Indonesia (4) Characteristics of genetic were observed does not related with vernacular names those were given by local people (5) Papua islands, Indonesia territorial is proposed the center of sago palm diversities, (6) Papua islands, Sulawesi islands and Kalimantan islands will be the provenance of the diversities (7) Genetic improvement of sago palm might enhanced using molecular marker that link to interesting genes by developing marker-assisted breeding.
