人体器官,就像人类的心脏一样,在时间的历史中已经发生了变化和演化。人类的大脑也不例外。根据查尔斯达尔文关于自然选择的观点,拥有能够复杂功能的大脑的物种似乎是一种有利的适应。接受和理解新情况的能力对于智人的生存证明是非常宝贵的。一些科学家认为,随着地球环境的进化,人类也会这样做。在这些环境变化中存活的能力直接归因于大脑的大小和功能来处理信息并对其采取行动。在Ardipithecus群人类祖先统治期间,大脑的大小和功能与黑猩猩的大小和功能非常相似。由于当时的人类祖先(大约600万到200万年前)比人类更像猿类,所以大脑仍需要像灵长类动物一样运作。即使这些祖先至少部分时间都倾向于直立行走,但他们仍然会爬树并生活在树林中,这需要与现代人类不同的技能和适应性。在人类进化的这个阶段,较小的大脑足以生存。在这个时期结束时,人类的祖先开始弄清楚如何制作非常原始的工具。这使他们开始捕猎更大的动物并增加蛋白质摄入量。这一关键步骤对于大脑进化是必要的,因为现代人类大脑需要恒定的能量来源以保持其运转速度。这个时期的物种开始移动到地球的不同地方。当他们搬家时,他们遇到了新的环境和气候。为了处理和适应这些气候,他们的大脑开始变大并执行更复杂的任务。现在第一个人类祖先已经开始扩散,每个物种都有更多的食物和空间。这导致个体的体型和脑尺寸增加。这个时期的人类祖先,如南方古猿集团和Paranthropus集团,在制作工具方面变得更加精通,并获得了火力以帮助保暖和烹饪食物。大脑和大脑功能的增加需要为这些物种提供更多样化的饮食,并且随着这些进步,这是可能的。

新西兰奥克兰大学论文代写:人体器官

Human organs, like the human heart, have changed and evolved in the history of time. The human brain is no exception. According to Charles Darwin’s view of natural selection, the possession of a brain with complex functions seems to be a favorable adaptation. The ability to accept and understand new situations is invaluable to the survival of a Homo sapiens. Some scientists believe that as the Earth’s environment evolves, humans will do the same. The ability to survive these environmental changes is directly attributable to the size and function of the brain to process information and act on it. During the ancestral rule of the Ardipithecus group, the size and function of the brain are very similar to the size and function of chimpanzees. Since the human ancestors of the time (about 6 million to 2 million years ago) were more like apes than humans, the brain still needed to behave like primates. Even though these ancestors tend to walk upright at least part of the time, they still climb trees and live in the woods, which requires different skills and adaptability than modern humans. At this stage of human evolution, the smaller brain is enough to survive. At the end of this period, human ancestors began to figure out how to make very primitive tools. This allowed them to start hunting larger animals and increase protein intake. This critical step is necessary for brain evolution because the modern human brain needs a constant source of energy to keep it running. Species of this period began to move to different parts of the earth. When they moved, they encountered a new environment and climate. To handle and adapt to these climates, their brains begin to grow larger and perform more complex tasks. Now the first human ancestors have begun to spread, and each species has more food and space. This results in an increase in the size and brain size of the individual. Human ancestors of this period, such as the Southern Gulin Group and the Paranthropus Group, became more proficient in making tools and gained firepower to help keep warm and cook. Increased brain and brain function requires a more diverse diet for these species, and with these advances, this is possible.
