Ben Domestic chickens were bred from particular species of
wild jungle fowl, I believe, so it was a rather rapid case of actual intelligent design, as most farm animals are.
Perhaps spot the Sri Lanka
Jungle fowl with many species of owls, terns, gulls, eagles, kites and buzzards.
Becoming what other people think of as domesticated chickens may take more time:
jungle fowl hens that lay eggs year - round and are big enough to eat.
Green jungle fowl (Gallus varius), are an exotic and shy relative of the domestic chicken and are endemic to Indonesia.
A breeding experiment with wild
red jungle fowl, the precursor to the domesticated chicken, may help explain whether selecting for tameness is the triggering event of domestication and all its characteristics.
He is looking more closely at the neural crest in
the jungle fowl.
Most researchers believe that Gallus gallus, the red
jungle fowl, was first domesticated in East or Southeast Asia.
Like the rats, mink and foxes in Novosibirsk, Jensen's
jungle fowl are bred to be more (or less) fearful of humans than their ancestors were.
From the beginning, the researchers took great pains to select birds only for their behavior:
Jungle fowl were tested for tameness at 12 weeks old, before they reached sexual maturity.
Neither researcher knew whether they were testing
a jungle fowl from the tame or fearful line.
That is what Cedric Tan, a Ph.D. student at the University of Oxford in the United Kingdom, used to explain his research on sperm competition in the red
jungle fowl.
They also brought small pigs, dogs,
jungle fowl, and probably rats as stowaways.
You would think that after millennia of egg - laying by the faithful gallus gallus (a.k.a. the red
jungle fowl) the business of cooking their gifts would be done and dusted.
