(5) The softening of foods made it easier for the body to absorb needed nutrients. (5) One essential ingredient is beneficial for the human brain, omega-3 fats. (4) Archaeological evidence, some 200,000 years ago, gave a theory that Neanderthals certainly used fire to cook. (5) Evidence showed that, “Until the American Revolution, 98 percent of the population lived along rivers and oceans,” (4) and with that diets rich in fish had the brain food of omega-3 fats. (4) When migration went inland nutrition suffered. (4) The flora and fauna of wet lands was not found in land, thus the diets of the migrants who lived away from rivers and oceans suffered greatly with their diets. (3 & 4) As the topic of omega-3 fats and fish, and migration and diets of in land migrants compose a concern for diets of earlier times, fire and cooking was evidence of brain power. (3 &4 & 5) To link omega-3 fats in fish, migration, and fire of cooking together researchers looked at brain sizes. (4 & 1) Brain size linked these areas together. It was the size of the brain that led to the belief that cooking was a part of humans of today’s ancestors and nutrition from fish high in …show more content…
(3) The Columbian Exchange brought plants and animals from the Old World to the New World and vice versa. (3) Along with plant and animal life it also exchanged diseases across the two Worlds. (3) However, it was the horse that was the most beneficial animal that the Old World introduced to the New World. (3) The horse was the one item that boosted the lifestyle of those who lived in the New World. (3) The horse could help plow a field, go on cattle drives, and became a valuable war weapon-the Calvary. (3) The horse was just one aspect of the Columbian Exchange. (3) The exchange of foodstuffs was vitally important to humans in both the Old World and the New World. (3) “But possibly it will never be repeated in as spectacular a fashion as in the Americas in the first post-Columbian century, not unless there is, one day, an exchange of life forms between planets.” (3) The foods that came from the Old World include wheat, chickpeas, melons, onions, radishes, salad greens, grape vines, sugar cane, fruit stones, and the potato. (3) Old World foods include maize, the most important to their way of life, manioc, tobacco, cocoa, paprika, guaiacum, sassafras, and American cotton.(3) The exchange of the foodstuffs was valuable to each culture, for example bread was very essential to the diet of Europeans. Likewise, maize was very fundamental to the diet of Native
