We need to rethink what evolution is all about. Have we evolved in terms of health, longevity, compassion or stewardship of the planet? I believe not. Indeed the evidence suggests we have, indeed, devolved.
The following information regarding ancient human beings speaks to the development of agriculture, as well as a devolution that has fostered a wreckage of our lives. Granted, people state that many of us have evolved since the time of agriculture. However, in reality, there have been tribes that had peoples who lived for hundreds of years. Consider reading the following:
The Hunza People Are Able to Live up To 145 Years Old! There have been other cultures scattered throughout the world that fostered long lives that has been reported in current scientific findings.
Indeed, our notion of long life expectancies may not be just through the current age of farming and industries. Apparently the farming industries may have actually lessened longevity in various cultures. Consider the following:
Over the course of thousands of our planet Earth's history, human beings have been on this planet. During approximately 50,000 of those years, The Bronze Age, (c. 3300 BC), the world witnessed the intensification of agriculture in civilizations such as MesopotamianSumer, ancient Egypt, the Indus Valley Civilization of South Asia, ancient China, and ancient Greece.
During the Iron Age and era of classical antiquity, the expansion of ancient Rome, both the Republic and then the Empire, throughout the ancient Mediterranean and Western Europe built upon existing systems of agriculture while also establishing the manorial system that became a bedrock of medieval agriculture.
During the Middle Ages, both in the Islamic world and in Europe, agriculture was transformed with improved techniques alongside the diffusion of crop plants, including the introduction of sugar, rice, cotton and fruit trees, such as the oranges to Europe by way of Al-Andalus.
Regarding life during ancient living, there is also a lot of variety. Different cultures have had high levels of long life spans while others appear to have lower ones. Everything in our world is variety. It's filled with various "colors", or in this case, people living within particular ecosystems and lifestyles. Walk around the woods, and you'll find a variety of trees, animals, and even the temperature based on the trees, sun, etc. Standardization, the corporate lover, is a blatant lie.
Towards the end of the Middle Age (Dark Age) we moved towards taking over the world as reflected in the voyages of Christopher Columbus in 1492. After which the Columbian exchange brought New World crops such as maize, potatoes, sweet potatoes, and manioc to the Natives.
