There are some studies using DNA... but they discuss migration to SA. What I want to know is if MY birds came from SA within a few generations ago, as I have been told. I *think* that the addition of commercial-ly type chickens to SA in the last 100 years would make it impossible for DNA to tell me this. I *think* it would only be possible if the SA birds had remained in a bubble. Thoughts?
That's a really good point. I initially had an Indiana Jones story in my mind whereby Kermit's Dutch collector from Hawaii travels into the vast remote of South America. Departing from known civilization, compass and walking stick in hand he knows he's risking certain death (but hey, he's got on sturdy shoes and a hat so what could go wrong?). He returns months later, clothes tattered, eyes listing a bit from the hallucinogenics endured while gaining the trust of toothless shamans, and a basket made of rain forest vines slung on his back. As he approaches you hear a strangely melodic, laughter like crowing and see that he holds in his arms chickens of the most amazing array of colors ever imagined. A package of eggs all different shapes and colors is tucked away under his hat. Tatooed on the his right leg is a map and on his left are the names of the kinds of chickens he's collected. He's completely beyond human exhaustion but just before falling into a never ending coma he whispers "Give my birds to Kermit".
Over time my vision evolved to an old guy enjoying his last few years living in rural Hawaii. One night there's a party and woozy from the exotic ambiance he tells his cranky-pants neighbor that the crowing rooster is actually blah blah blah. The cranky neighbor leans into the story so the old guy keeps talking because he figures maybe the neighbor won't complain so much.... Then the old guy dies but the story sticks and the birds get packed up and pawned off who ever would agree to care for them. How they get to the mainland I don't know.
However, now I think perhaps somebody somewhere got some birds for all the wrong reasons and they got mixed in with birds being kept for socially inappropriate reasons. Who knows. It doesn't take more than a few generations for a lineage to completely change appearances, especially if the initial few genetic contributors have buff feathering and duplex combs. That's largely why I've become so intrigued with egg shell traits - it takes longer for the gene combinations to drift enough to no longer be able to recognize a lineage based on what the eggs look like.
OK - back on task - how long would it take me to decide to use a chicken for a ritual instead of chasing some spry little wild bird up into the cloud forests? Not very long if chasing the wild bird meant getting in the cross hairs of whatever warfare was underway. It's been one thing after another after another there for so long that it seems like breeding the chickens to meet a specific ritual need would just make good security sense. Why risk not being able to do the ritual when you can have your bird and eat it too..... (Oh, my.)
Still, it doesn't solve the basic stumbling block that there was no Indiana Jones of South American poultry. Maybe there was a Dutch tourist who bought some birds at a live market and took them home to Hawaii. But, if the chickens in South America don't predate the Europeans, then the primal mystique of the story if over for me. What we're left with are some birds that we think are fascinating and can generally group based on phenotype but really the only reliable thing they have in common is with Kermit.
If genetic testing was done what would you be looking for &/or what would you compare it to?
