Want info on the origin of chickens
Jeff Root
developed by domestication and breeding, or did chickens per se
already exist before humans started domesticating them?
Can anyone provide a link to images of what the immediate
precursor of the chicken looked like or may have looked like?

This is a subject that I know only a little about. To the best of my
knowledge domestic chickens are probably descended from Gallus gallus,
the red jungle fowl. There seems to have been some investigation into
whether the domestic fowl is descended from just one single species or
more than one. Apparently 4 species have been considered, G. gallus (red
jungle fowl), G. lafayetti (Ceylon jungle fowl), G.sonerati (grey jungle
fowl) & G.varius (Java or green jungle fowl). Various theories seem to
have been put forward. That present day domestic fowl have been derived
from a single species, or have been derived from two or more of the
above species. Another theory being that some breeds would be descended
from one species while other breeds would be descended from another
species.
I think that the strongest evidence points to domestic fowl being
descended from G.gallus.
I've an idea that Laurie would know more about this subject than I do.

This is a nice website. Along with red jungle fowl there are
pictures of the green jungle fowl and grey jungle fowl.

This is what I have learned, too, from my friend Armin Six.
Archeological findings in North-Eastern China seem to suggest that
chickens were kept there 5,900 - 5,400 b.C. (this is outside the natural
territory of G.gallus). In Syria, chicken bones from 2,500 b.C were
found, and in Greece there definitely were chickens by 1,000 b.C.
A very early development into two groups of domestic chickens is
therefore very likely - Asian breeds that were formed in the natural
territory of the jungle fowl, and the breeds that were developed as
domestic chickens spread to the West. 3,000 - 3,500 b.C. they may have
already been kept in South-Eastern Europe (Ukraine, Moldawia), but
certainly by the time of 700 b.C.
500 b.C. chickens had reached Italy, probably even earlier. 600 b.C.,
celtic people in what is Germany today, kept chickens. The oldest living
German breed came to Germany in the 12th century, probably from Bosnia.
The Romans already brought crested chickens to England, but they only
came to the Netherlands in the 15th and 16th century, when they were
imported from Russia by trading ships.
