Collective Learning in Medicine By Amari Dabadghav per.2

Threshold #6: Collective Learning

Main Points in Threashold #6: What kind of creature are we? How are humans distinctive? Humans are threshold 6 because during the four billion years of life humans are the only creatures that have been able to pass down information to one another. Which has made us the most powerful species of all, we can learn and pass on. Instead of learning something and the next generation learning that same thing again by trial and error, we share that knowledge, so the next time it comes along we know exactly what to do and what not to do. Also, what makes us such a unique and powerful species is the ability to use symbolic language. We can write things down to pass on, but even before that we used art to tell stories, give warnings, and to portait important things that people in later generations need to see or remember. Then over the year we add thing to it and create something better and more correct with new information, but we wouldn’t be able to do this without the old information. All of the gives us the ability to manipulate our environment to exactly what we want it to be. We can take the information we have and take control over everything in outreach, whether it’s our environment, the other creatures in it, or other humans. Humans are closest related to chimpanzees, over 98% of our DNA are the same as chimps. We are more closely related to them than any other apes.

Human Evolution

Hominine Evolution: Our species started to evolve when the temperature declined. The temperature was also more erratic. Our world has swung from ice age and back again perhaps seventeen times. Most of hominine fossils have been found in Africa. From clear evidence it is now believed that humans originated in Africa. We came from apes, and long ago it is believed that apes were forced from trees and rainforests by climate changes and thinning forests. These lands now turned to grasslands and woodlands so the apes had to adapt. Forced to walk upright in these new terrains, was the first sign of them evolving. This is called “bipedalism”, bones of the earliest known fossils are evidence of this. ‘Ardi’; a female dated at about 4.4 million years ago. The most well known fossils are those of Lucy, dated about 3.2 million years ago. Called “Australopithecus”, or “Southern Apes”. Next these apes learned and improved coordination; they learned to dance and to move in unison. Then these hominines learned to use tools. By about 1.8 million years ago a new species appeared Homo erectus. The size of their brains had been increasing, and in this species it reached about 70% of the size of modern human brains.

Modern Humans

Appearance of Modern Humans: After close to 2 million years of Homo erectus, a new species ourselves, people about 200 to 250,000 years ago somewhere in Africa. A group of Homo erectus may have become isolated by mountain or river, or the genetic changes may have happened along the coast. Minor genetic changes occurred that spread rapidly in a small population. In our story for this difference constitutes threshold six--the Amerge of the first to large species ever to change the face of the earth in such a short period of time. We humans are associated with greater impact and greater energy flows than ever before in planetary history. What makes humans distinctive from our past species? Experts have a long argued about was is distinctive about modern humans. They used agree that tools distinguished us. Now they tend to think that our chief distinction is the way we use language, symbolically and grammatically, Which permits precise meaning to be conveyed. This story who began using the term "Big history” was David Christian, he also used the term "collective learning”. The thing that makes humans distinctive is the way we share knowledge. Instead of one learning something and then the next generation having to learn this again, we share information and stories to help past pertinent information to the next generation. Even from long ago humans have passed on knowledge, Either through paintings or drawings or even the written word. Through this knowledge started accumulate, Through this accumulation we started to surpass every other species on the planet. All of this makes us the most powerful species. But with knowledge comes great responsibility.

Stone Age and Use of Tools

Paleolithic (Stone Age) Life: “Paleo” is the Greek word for “old” and “lithic” Greek for “stone”. Paleolithic in English refers to life back to the earliest use of stone tools, some 2.6 million years ago. We also use it to mean the life of modern humans, starting when they emerged down to the beginning of farming, about 10,000 years ago. Paleo people lived by hunting animals, gathering fruits, nuts, and roots. Usually they had to move around a lot to find food; they lived a nomadic life. For the first 100,000 years or so, humans were moving around Africa. After that the first ones moved out of Africa to the Middle East, starting a migration that 85,000 years later covered the globe except America.

Goldilocks Conditions: The society we live in came by chance, it was a series of coincidences and good luck, if one of the important things that created the world happened a few minutes later, we could not exist. Time and history could not exist. The conditions that let humans evolve and live were because of goldilocks conditions, meaning: The conditions of many things that created the present world had to be perfect for life to be successful,but it was just all just good luck; a fluke.

Collective Learning: The reason humans are set apart from the other creatures in the world and universe is because we have to ability to learn then pass that knowledge to others keep the flow of information constant and ongoing. Building and building and evolving, once we learn something we can write it down and never have to face it again. We even learned how to use our surroundings for medicine or tools to make other things.
