A.D: 830: A storm sends an Indonesian trading ship drastically off course. Months later, dozens of ragged survivors make landfall on an island off the southeast coast of Africa, more than 3,000,miles from ho Today, Murray Cox, a computational biologist at New Zealand Masses University, says a scenario like this may describe.the gloomy origins of the first permanent settlement on.Madagascar, home to about 22 milion people-today 2 Genetic and linguistic studied suggest the islands native Malagasvpeople are mainly of Indonesian descent. The idea of early Indonesians traveling 3,000 miles to the island intrigued. Cox. Its a surprisingly long distance to come, he says. So he used computer modeling to purse the clue, running theo settlement simulations. Cox soon pispointed one that would explain the una pattern evident in Madagascar today. Surprisingly, the current populations descends primarily from just 30 or so Indonesian women who arrived 12 ceinturies ago. His conclusion is supported by prior finding that about 30 percent of Malagasy have the same mitechondrial una, which is passed from mother, to child-far less diversity than in typical human populations, which share less than 2 percent. This suggests rapid, recent growtg from a very small founded populations, Cox says It is unclear how Madagascars founding mothers (and the fathers who must have been with them arrived. Cox, proposed scafaring merchants throws off course, or refugees fleeing political strive; the latter could explain why women, usually not found on trade ships, were on board. Now, Cox plans to explore whether small founding groups are characteristics of other early island settlement, including Hawaii. There may be general rules for settling islands, he says.
