The Moray ruins.

The deep bowl shaped hollows of Moray look like a Roman amphitheater.
They are *circular* in shape and have stair like terraces climbing up to the valley floor above.
It is widely believed that the
ruins were an *agricultural laboratory* used by the Incas. The
circular terraces that lie here are thought to have been used as an
agricultural *research* station. Their depth, design, and their
orientation with regard to the sun and wind are all telltale signs that they have a specific purpose. Because of the different conditions at each level of the terraces there is a difference in temperature of 15 °C. from the top to the bottom. It is thought that the Incas used the terraces and the different temperatures to test crops and *experiment*
with them. The different *micro climates* at the different levels
allowed them to study wild vegetation.
They used hybridization and modification to adapt crops to make them suitable for human consumption.
Peru is famous for its many variations of potato. This is down to the Incas. They experimented and played around with science. And now Peru has more than 2,000 varieties of potato.
It is no coincidence that the *temperature* differences at Moray represent the temperature at sea level farmland and the temperature in Andean farming terraces. The Incas were beyond their time in scientific thinking. Studies done on the soil has shown that the soil comes from
different regions and must have been brought to the Moray.
This again shows that the Incas were using this area as an experimental zone. Another fascinating point to note about the Moray ruins is that they never flood, even in Peru’s unremitting rainy season. It is thought that there must be *underground channels* built to allow the water to drain.
