Is Human Survival Selfish? Fight or Flight Explained

Weekly TestTubePlus introduces topics from various perspectives. This week, Trace will discuss the survival problem. What exactly is survival, how this concept changes over time, and how do humans live in cities and urban areas? First of all, what is survival?

In the late nineteenth century British naturalist Charles Darwin shocked the world when introducing the idea of ​​"survival of the fittest". According to his new theory, humans are not placed on the earth, but evolve over time, in fact they share a common heritage with all other species on the planet. Selection of two different types (selection of species or species of arbitrary design) of environment selection (genetically genetically defective species ultimately do not exist in the element) and sexual choice (seed species or arbitrary design species) Design defects can not survive defects appear weak and are not suitable for playback.

All genes that survived both of these selection processes will be transmitted on - line, and species will ultimately acquire new genetic variants through random mutations that increase or decrease the likelihood of surviving in the environment. Today 's humans are making much more effort than things other than living things to focus on other people and animals. Even inanimate objects are the major danger of most people in our urbanization area today. This means that at our core, even the most bureaucratic pencil-led salaried workers have deep-rooting hunting functions.

TestTube Plus is designed for enthusiastic scientific enthusiasts who need comprehensive conversation about the topic they care about. The organizer Trace Dominguez will examine the details of key issues such as black holes, religious history, dreams, space travel, history of science, sex, and the latest trends and prospects.

"Although sometimes called modern Darwinism, the field of new science was not born of immediate evolutionistic psychology, but in recent years evolutionary psychology as discipline gathered momentum and respect In neuropsychology, palaeontology, and other scientific discoveries, evolutionary psychology, today's humans live in a world filled with contemporary space exploration and virtual reality, but hunter gatherers of the stone age The spirit to achieve this goal.

I know what you are thinking: What is the difficulty of human cooperation? It is not difficult to explain intolerance and self centricity (under the principle of survival of the fittest), but starting with peaceful coexistence, explain how human beings are tolerant and self-centered in the evolutionist past It is difficult. Selfish - Convenient, Cooperative - Hard Let's say you are a slave in a Greek kitchen boat. One of them is 40 passengers. Sweat, sweat, stretch wrinkles, nourish your ability to smooth muscles. Always be sure to reduce your output. Eventually, 39 other people are losing weight. Your work is more difficult than your partner, so you consume less calories and sleep less. I ate the assigned porridge, it is the same as the others. When they are completely exhausted and tired and fall into a deep sleep, you will sneak into some extra food. Because you work less and eat more, you are more healthy.

So, is human survival? This seems to be true. There are many examples of demanding human instincts that we can serve to keep alive. Perhaps the most obvious example is the battle or escape response created by Harvard physiologist Walter Cannon in 1915. When humans are in danger or under pressure, the bio trigger will help us decide whether to stay there, fight or fly. When we face stress or look at danger, the hypothalamus of the brain is activated. It starts a series of chemical and neuronal responses that we prepare for the next scenario. Adrenaline is released into the bloodstream, our heart rate rises, and blood sends quickly to our muscles and limbs. Our consciousness, vision, impulse are intensifying and accelerating. You can thank the ancestors of our caveman. Early people faced a lot of dangers and reactions to fighting or running to develop to help them escape or to overcome these dangers to survive developed.
