Evidence that ancient farms had different origins than previously thought

The tropics being the tropics (lots of plant growth), it was probably difficult to do such studies before the era of satellites and lidar that is able to penetrate the forests and topsoil to reveal just what was hidden.

Going forward, we'll probably learn much more about the practice of ancient agriculture and hunter-gathering societies in tropical regions.

BTW, Paleontology has a similar problem. Most fossils are found in deserts or as part of construction work simply because they are easier to find in those areas. There are probably as many fossils buried in tropical regions but the difficulty of digging through the tropical forests to find them limits the number of fossils found.

As far I know, the classic knowledge was that agriculture raised nearly at same time from the fertile crescent & Egipt, China, Indus valley and central America.

I read about Gobekli tepe. It's a interesting ruins, not only because are very old. Also, shows a very advanced knowdlege about how sculpt stones. Take a look to the animal scupts on the stones. They are very detailed. They look really advanced for being too old.

Another interesting old ruins are :

- Yonaguni Monument . The last time that this ruins was over the water was 9000 years ago!

- Sumerged ruins of Gulf of Khambhat . Very old cities of Indus valley that are from 7000-9000 years. And if I remember correctly there was a urbanized zone big as new york itself!

- Tiwanaku . Where we can found something like a mass produced stones with a really awesome quality. Look like these pre-incan culture discovered Ford's production chain and apply over standarized stones that can put like a gigant lego, and not need any kind of cement to stay together!

The real truth is that we don't know very well these ancient eras. We assume that our ancestors must be more stupid that ours. But this is false. They are equal capable that any actual person. We only, don't know how they did it, or when (exactly) they did something or how many times something was rediscovered.
