In the Denver Art Museum’s Art of the Ancient Americas galleries, we worked with Mexico City-based animators Hola Combo to create animations to help tell the origin stories that explain the relationship between ancient American communities and the their environment. For the Andes, we chose a story that loosely relates to the works on display. “The Legend of Ñaymlap” is an ancient story from Peru’s northern coastal communities and supposedly records the origins of the Sicán or Lambayeque dynasty (about 750–1375 CE). Within this origin story, there is a moral about the relationship between the deities and the land. As the ruler turns away from the deities, rain and floods devastate the land, starving the community.
Cusco, a city in the Peruvian Andes, was once capital of the Inca Empire, and is now known for its archaeological remains and Spanish colonial architecture. Plaza de Armas is the central square in the old city, with arcades, carved wooden balconies and Incan wall ruins. The baroque Santo Domingo Convent was built on top of the Incan Temple of the Sun (Qoricancha), and has archaeological remains of Inca stonework.
Machu Picchu is an Incan citadel set high in the Andes Mountains in Peru, above the Urubamba River valley. Built in the 15th century and later abandoned, it’s renowned for its sophisticated dry-stone walls that fuse huge blocks without the use of mortar, intriguing buildings that play on astronomical alignments and panoramic views. Its exact former use remains a mystery.
We discuss the meeting between Vladimir Putin and Xi Jinping as Russian troops continue to surround Ukraine. Plus: the political scandal engulfing Peru’s government and a Winter Olympics preview.
Challenging the dogma of gene evolution, and how chiral nanoparticles could give vaccines a boost.
In this episode:
00:45 Genome mutations may be less random than previously thought
A long-standing doctrine in evolution is that mutations can arise anywhere in a genome with equal probability. However, new research is challenging this idea of randomness, showing that mutations in the genome of the plant Arabidosis thaliana appear to happen less frequently in important regions of the genome.

How hallucinogenic beer helped cement an ancient superpower’s control, and a surprisingly enormous colony of breeding fish.
Research Highlight: Drug-fuelled parties helped ancient Andean rulers to hold power
Research Highlight: Vast fish breeding colony is more than twice the size of Paris
16:11 How a left-handed nanoparticle could give vaccines a boost
The chirality of a molecule – whether it has a left- or right-handed orientation – can have significant impacts on how it works. This week, a team show that left-handed gold nanoparticles can stimulate the immune system of mice, and boost the activity of a flu vaccine.

Peru is a country in South America that’s home to a section of Amazon rainforest and Machu Picchu, an ancient Incan city high in the Andes mountains. The region around Machu Picchu, including the Sacred Valley, Inca Trail and colonial city of Cusco, is rich in archaeological sites. On Peru’s arid Pacific coast is Lima, the capital, with a preserved colonial center and important collections of pre-Columbian art.
Dr. Albert Lin is investigating the true origin of the ancient story of the great flood. In his search for answers he comes to the lost city of Chan Chan where the Chimú people have recorded a violent shift in the ocean currents.
Chan Chan is located in the mouth of the Moche Valley and was the capital of the historical empire of the Chimor from 900 to 1470, when they were defeated and incorporated into the Inca Empire. Chimor, a conquest state, developed from the Chimú culture which established itself along the Peruvian coast around 900 AD.
Chan Chan is in a particularly arid section of the coastal desert of northern Peru. Due to the lack of rain in this area, the major source of nonsalted water for Chan Chan is in the form of rivers carrying surface runoff from the Andes. This runoff allows for control of land and water through irrigation systems.
