# First Peoples Reach the Isthmus (c. 11,000 BCE)

Location: Isthmus of Panama
Themes: main-event

The Isthmus of Panama rose from the sea around three million years ago, joining North and South America for the first time in tens of millions of years. The new land bridge triggered the Great American Interchange, in which animals such as ground sloths, armadillos and opossums spread north while big cats, horses, camels and mastodons moved south. By the end of the last Ice Age the isthmus was covered by a mosaic of dry forest, scrub and grassland, with lower sea levels exposing broad coastal plains. Human beings followed the same corridor. The earliest secure evidence of people in Panama dates to roughly 13,000 years ago, in the form of fluted stone spear points of Clovis-like type and the "fishtail" points typical of South America. Such points have been found on the shores of Lake Alajuela in the upper Chagres basin, at La Mula-Sarigua and Vampiros on Parita Bay, and at other sites in central Panama. They show that small mobile groups hunted large game and gathered plants as they moved between the continents. Panama therefore lay on the main route by which the first Americans reached South America. Because the isthmus is so narrow, two technological traditions of the Paleo-Indian world, the northern Clovis and the southern fishtail, meet here, making the region crucial for understanding how and when the southern continent was peopled. At this point in the timeline (c. 11,000 BC), no ruler of the isthmus is recorded in this dataset; the land was home to indigenous communities and chiefdoms known mainly from archaeology.

## Why it matters
Panama was the gateway through which the first humans entered South America, and its sites preserve evidence of both northern and southern Paleo-Indian toolmaking traditions.
