excerpt from “Shoes: Feet First!”
from A History of Travel in 50 Vehicles
by Paula Grey & Phillip H.
[[ Based on the fossil evidence and genetic (DNA) analysis, scientists believe that modern humans (Homsapiens) developed in Africa some 200,000 years ago.]] Approximately 60,000 to 80,000 years ago, they traveled by foot to Asia, then settled what are now Indonesia, Papua, New Guinea, and Australia. By 35,000 years ago, modern humans were firmly established in most of Europe. [[Finally, approximately 20,000 years later, humans trekked from Asia to North, Central, and South America—again on foot, crossing the Bering Strait land bridge.]]
The earlies shoes archaeologists have found are sandals dating from approximately 7000 or 8000 BC in the Fort Rock Cave in Oregon. The oldest leather shoe, a piece of cowhide laced with a leather cord, was found in a cave in Armenia in 2008 and is believed to date back to 3500 BC. The terrain around the cave was rugged, with sharp stones and spiky bushes. [[Temperatures in the area could range from up to 113° Fahrenheit (45° Celsius) in summer to below freezing in winter.]] Shoes would have enabled people in the region to cope with the terrain and the temperatures. [[Obsidian, an igneous rock from at least 75 miles (120 km) away, was found in the same cave, showing that they traveled long distances.]]
