It is 400,000 years ago. A man sits in the mist of the jungle observing two rocks in his hands. Perplexed by their texture and strength, he strikes them together igniting a short spark. Amazed by the phenomenon he has created, he keeps striking the rocks until a huge spark ignites, not only burning his fingers, but setting the plants in front of him on fire. This man, classified as Homo erectus, has set the turning point to the human evolution. Neurobiologists and researchers claim that the discovery of fire has allowed humans to cook food, obtain warmth and protection, and increase over all human activity, all leading to the terrific growth of the human brain. Today, our brains have evolved so complexly that we are not only able to think and communicate, but believe and process both the transcendental and experiential aspects of religion.
500,000 thousand years ago, the hominid brain tripled in its size. Recent studies from Timothy Rowe at the University of Texas in Austin revealed that the first big increases in the brain size were in the olfactory bulb, suggesting that the early humans heavily relied on their noses, helping them sniff out food (Robson, 4). Through the use of fire, early humans were eating more nutritious food that in effect, helped grow their brains. Much of the brain's expansion took place in the neocortex. This part of the brain is involved in processing higher order cognitive functions that are connected with human religiosity. The neocortex is associated with self consciousness, language and emotion. According to Dunbar's theory, "the relative neocortex size of any species correlates with the level of social complexity of the particular species. The neocortex size correlates with social variables such as...

...opment of language, tools, and belief systems all lead to the ultimate creation of religion. Religions are practiced by over 90% of human beings on earth today. The feelings of connection people experience from religion are a function of neurochemistry. Rituals and social or religious gatherings act as serotonin factories to the brain, uplifting one’s moods. Humans created religion to have hope and purpose in their lives when it was dark ad difficult. They wanted to find ways to strengthen their commitments when they felt adrift. Our brain has evolved over centuries, adjusting to circumstances, and growing rapidly to make us more complex beings. It has provided us with religion, giving us a sense of community when we felt isolated and alone. Our brain has provided with morals and principles that are impossible for us to outgrow today. After all, it made us humans!
Following this central theme of humans and fire, Wrangham shares with the reader the plethora of theories that have been developed in the hopes of explaining the modern human brain. He settles on what he declares most plausible, the social brain hypothesis, which compares brain size with the size of mammalian guts. Following this hypothesis, it is proposed that more effective food preparation, with fire, would have allowed for more advanced digestion, and thus more advanced
There is no society without religion. James has also states that religion is “personal destiny”, which means that it existence is infinite in human life. Human lifestyle has been influence by the religion, so religion is a principal factor in universe. Religion is based on different believes and practices of humans which is totally understandable, despite of difference in religion people have same shared belief of putting their God above the others and shows the love and affection toward it. God has created this universe, the specious around us is the sign of his existence.
Throughout and for many years there has been a lot of controversy on how to trial someone who has committed a crime under the age of 18. A lie will be a lie even if it 's serious or innocent and that 's why just like a crime will always be a crime, no matter what the situation is. The age of a person who has committed murder shouldn 't be an issue or a complication. Many advocate that the juvenile is just a child, but despised that I believe that is no justification or defense for anyone who does a crime. America and the nation need to apprehend that juveniles that are being conducted to life in prison is not just for one small incident or crime, but for several severe crimes according to Jennifer Jenkins, Juvenile Justice Information
It has been proven that a child’s early years are the peak at which the mind can bend and shape, creating the foundation for a life. We know now that even before birth, the mind is a delicate matter that if improperly taken care of could alter a person’s entire life. Nourishment and stimulation before and after the birth of a child mold’s the brain in its most malleable state. Medical and scientific institutes paired with parenting information organizations have made information readily available for parents, childcare providers, and students to advise them of the importance of childhood brain development. This information is not only critical for the child, but for the person they will become in the future.
Religion comes from religare, which means have a reunion. Aneel Baquer says that humans have a need to connect with others, the ability of myths and thoughts of religion is a desire that humans need to bond. In most civilizations, religion is the reason why civilizations are successful. Religion give, people a motive to survive or do what they do. Sometimes the religions actually make their civilization expand and even more successful. not only does religion give us a motive to survive. Still today, religion is one of the biggest factors in modern civilizations. In several religion motives are used for example, christianity. In christianity to meet with god, you must do good. Religion can change a persons personality by aiding from stress, to giving hope. Religion can also reduce the fear of death. In ancient civilizations, egyptians did not fear death. In their religion they believed that living on earth was the beginning of life. Once dead it sends you to the beginning of happiness or horrible. Religion can also expand. If you have a strong connection to your religion, some people spread the word of their religion to other people. It also teaches manners and the difference between the good, and the evil. Vikings were such a significant civilization than any other because of their religion. Religion for the vikings have given them motivation to expand territories, learn between the good and the bad, and not to fear death but to welcome death; reasons why are from being taught was from viking mythology, heroic people and their warlike god.
The necessity of religion is a topic that has been widely debated by many people for many years. The vast majority of the 7 and a half billion people on this earth practice some sort of religion but for what purpose? Whether it’s too give people hope for an afterlife or too fuel their need for contact with others people can list hundreds of different reasons why they rely on religion but is religion actually essential to our wellbeing and and life quality on this planet?
Religion has always been able to give people something to look to for help. It answers their questions and gives them hope for the future. In the Christian faith, followers are taught that Christ will help them if they believe and follow Him. The painting by Carl Bloch Christ Healing at the Pool of Bethesda is a prime example of Christ helping and healing those who are experiencing times of hopelessness, and need someone to turn to. Religion is what helps ground people and gives them hope. If we didn’t have religion people would be lost and in darkness.
Religion is a symbolic representation of society. The sociological approach to religious belief looks at how society behaves on a whole, to answer the question, “Why are people religious?” We express our participation in religious events through plays, acts of confession, religious dances, etc. To begin to understand why we have such term, let’s understand the common elements of religion. There are different types in which people believe in or follow and that is: animatism, animism, ancestral spirits, god and goddesses, and minor supernatural beings. Beyond these different elements, such one is to have religious leaders to follow.
While the concept of the “triune brain” is, as a whole, wrong, MacLean in 1970 did propose some interesting ideas about the evolution of the brain. He proposed that there are three main layers of evolutionary progress in the human brain. It starts in the middle with the most basic, the reptilian brain. The reptilian brain is the brainstem itself, and is responsible for the most basic of survival behaviors. The next layer out is what he called the paleomammilian brain, which is where MacLean says we find the limbic system. This part of the brain deals with social and emotions, and MacLean argues that most mammals have this. The third and most complex layer is the neomammilian or neocortex that deals with the highest of cognitive functions. LeDoux argues that while MacLean was fundamentally wrong about the physical layers of the brain, he was not far from the truth about the evolutionary brain. Emotions at the core are in part for survival, and so therefore the more complex the emotion, the more complex the functions needed.
As far as mankind’s history can date, religion has had quite an intimate relationship with people. Although maybe it hasn’t always been identified in the same way as we identify religion today, spread across the world we have the remains of pyramids, temples, and even written in ancient texts from centuries ago dedicated to god, to the afterlife, to what lies on the other side. And up to today’s times, religion has grown along with man.
Sabbatini (2001), the human intelligence is defined as the key to a trove of understanding about ourselves, and how natural selection could produce such a marvel as the human brain and its capacities in such a short time (Renato M.E Sabbatini, 2001). The evolution of human intelligence is considerable as a mystery matter because the process of evolution is very difficult to be observed directly in the paleontological record such as blood, teeth or bond. Moreover, the evidence that scientists used to determine the evolution of human intelligence is the indirectly from the observation of the increase in the size of cranial capacity and also the action of result of human intelligence such as knowing how to use stone tools and be cooperative to hunt and war, the use of fire to cook, art and ritual and few other things. Furthermore, the article argued that the intelligence is not unique to humans. This is because current scientific view show that there are different level of complexity of intelligence also present in mammals and human share many features with animals which we were though it is only unique to human. In fact, it is not, such as symbolic language which has been determined it happened in
In Introducing Philosophy of Religion, Chad Meister asserts “there are several components (that) seem to be central to the world religion: a system of beliefs, the breaking in of a transcendent reality, and human attitudes of ultimate concern, meaning and purpose” (Meister 6). Throughout my life, I feel that religion is one of the core social belief systems that people use to maintain what they feel is a good way to live. Giving them a sense of purpose or fulfillment during their earthly life, most hoping whatever beliefs that have will help them after death. Even though there are many different religions or religious value systems, everyone has most likely been exposed to one or more. There is only 15% of the world’s population that do not believe in one type of religion or another (Meister, 7).
Brain Development is a nonstop development, we never stop learning so our brain isn’t going to just stop I mean well when it’s our time, but it won’t as long as you continue to learn and grow. The human brain begins to develop as early as three weeks after conception. But our brain development is a lifetime process. It doesn’t just stop developing at a certain age. There is a difference in brain development in children and adults the early life is impressionable then in the maturity aspect of life. This is a positive thing because as children they learn new thing they’re open to new and exciting things but then again it can be negative because children tend to be vulnerable to development problems. Our brain develops not only from nurture
Religion helps establish mankind’s place in the order of the universe. As civilization began to be established through the domestication of animals, the irrigation and cultivation of agricultural crops, and life became more complex (moving from mainly a hunter/gather existence to one that could settle down and have more time to consider advanced ideas) people began to consider questions such as, where life comes from, is there a creator or creators who helped make the world, and what happens after we die. Religion helped answer some of these questions. It gave people purpose, meaning, and perspective. Religion helped establish nations in the case of religious theocratic governments. In many of the ancient civilizations, such as the Egyptians, the Mayans, and even Mesopotamia, the priests and other religious leaders played prominent roles in help shaping the laws and government of these civilizations. As his...
Religion is the one element of life that has connected the races and societies of the world for hundreds of years. It has given meaning to lives that may seem otherwise hopeless. Religion has provided for a universal language and culture among those who believe in a higher power. The spirit or being receiving the worship and praise may not be the same, but the practices are usually similar and serve the same purpose--to give direction, insight, courage, and a divine connection.
