Intriguing Lime Green Blobs Appear In The Andes (NPR)

What kind of plant is this? In Spanish it’s called llareta, and it’s a member of the Apiaceae family, which makes it a cousin to parsley, carrots and fennel. But being a desert plant, high up in Chile’s extraordinarily dry Atacama, it grows very, very slowly — a little over a centimeter a year.

At that rate, plants rising to shoulder height (covering yards of ground, lump after lump) must be really, really old. In fact, some of them are older than the Giant Sequoias of California, older than towering redwoods. In Chile, many of them go back 3,000 years — well before the Golden Age of Greece.

Oldest High-Altitude Human Settlement Discovered in Andes


The oldest-known evidence of humans living at extremely high altitudes has been unearthed in the Peruvian Andes, archaeologists say.

The sites — a rock shelter with traces of Ice Age campfires and rock art, and an open-air workshop with stone tools and fragments — are located nearly 14,700 feet (4,500 meters) above sea level and were occupied roughly 12,000 years ago.

The discovery, which is detailed today (Oct. 23) in the journal Science, suggests ancient people in South America were living at extremely high altitudes just 2,000 years after humans first reached the continent.

The findings also raise questions about how these early settlers physically adapted to sky-high living. Read more.
