The study found that the chicken DNA molecular domestication originated from a common ancestor (monophyletic), namely species of red jungle fowl (Gallus Gallus).
"The results of this analysis also shows that Indonesia is one of three areas declared as a center of domestication of chicken first in the world except in China and India," says DNA Research Lab Research Center for Biology LIPI Dr. Sri Sulandari, who reached here on Tuesday.
He said, through DNA analysis of all the clumps of chicken in the world have made pilogeninya trees and clumps of chicken in the world grouped into seven clade, consisting of clade I, II, IIIa, IIIb, IIIc, IIId, IV.
He said that the chicken belongs to the class of bird, the order galliformes, phasianidae family and genus Gallus. Chickens that had been maintained widely included in the species Gallus Galus that were domesticated and named Gallus Gallus domesticus.
Other species that still live wild in the forests of the genus Gallus Gallus included in the Red Jungle fowl are spreading include China, India, and Southeast Asia.
While Gallus varius (Green jungle fowl) distribution includes Java, Bali, Lombok, Sumbawa, Flores, and small islands around it, Gallus lafayettii (Sri Lankan Jungle fowl) distribution only in Sri Lanka, while Gallus sonneratii (Grey jungle fowl) distribution includes India the south and west.
The development of science in the field of molecular genetics have opened new horizons and are widely used as an accurate taxonomic analysis tools.
The taxonomist in this century has been widely used application of DNA technology to distinguish different species of animals and the family relationships of a species with other species, he said.
"From this analysis of the domestication of chicken with red jungle fowl (G.gallus) kinship relations more clearly visible, namely the red jungle fowl was domesticated chicken in a large circle," he said
