The high Y chromosome diversity of Indonesian populations, Bali and Sumba islanders, suggests that these populations have existed since the Palaeolithic age [ 29, 30].
However, we detected no evidence of recent genetic bottlenecks in any of the populations, suggesting that the populations have existed in their current state long enough to reach migration-mutation-drift equilibrium.
These results strongly suggest that coastal populations are closely related whereas inland populations have existed in isolation for quite some time, and that genetic drift is responsible for the divergence in allelic frequencies and fixation of certain alleles.
The link between registration and eligible population, that has existed for nearly 100 years, will be broken.
But for years this population of about 30,000 people has existed under the threat of abductions and ritual killings, and in recent years the situation appears to have worsened.
A population-based FOBT screening programme has existed in Florence District since 1982, run by the Istituto Scientifico per la Prevenzione Oncologica (CPSO), its efficacy in reducing CRC mortality supported by a case control study (Zappa et al, 1997).
