The smaller the brain size of a primate, the group that they belonged to would likely be small as well. In contrast, the larger the brain size of the primate, the group that they belonged to would likely be larger. In the example from the video, we see the skull of a baboon who had the largest brain size within the example with also the largest group size of…
Explaining Evolution Evolution has always been a relevant topic, whether being explained in learning environments or thoroughly investigated by scientists, why is it so important? Evolution tells the story of how humans, as well as other species, came to be. The articles “12 Examples of Evolution Today” by Erin Brodwin and “A Possible Break in One of Evolution’s Biggest Mysteries” by Peter Brannen are both compelling with the information they provide, and contain insights into the world of evolution. Brannen’s article is specifically focused on the whale and studying the barnacles on their bodies to gain more knowledge on the story of their evolution, whereas Brodwin’s article is broader and shares information on different species that evolved…
In this passage, Eiseley purposes to explore the mystery of the rapid emergence of the human brain. While still a personal essay, Eiseley writes her philosophical work to anyone willing to listen, not singling anyone out throughout the writing. She begins by illustrating the theory of evolution that is the widely accepted theory of how humans developed; she describes how nature removed our primal instincts, replacing them with newfound brain cells. She then goes into the realization, not only amongst herself but for all readers, that the human brain is what sets them apart from other animals. She shows that how the human brain functions is, though it seems insignificant, miles ahead of the primitive ape.…

Not everyone is going to develop in the same way. Not everyone looks the same or is the same because everybody is different in their own way. So, why should brains be thought of all the same? “There is no single age at which the adolescent brain becomes an adult brain” (Steinberg 16-17).…
In chapter five, the emergence of culture, the authors ask the question of why natural selection allowed the brain to evolve in a way where culture became more likely among humans’ hominid ancestors? While the development of culture had allowed the organization of hominoid to increase in complexity, it was faced with many obstacles. The authors argue that the development of culture is anchored in the development of spoken language. As a result, the development of culture couldn’t occur without high level of brain rewiring in the brain, as well as, the shift in speech needed to accommodate visual dominance to work with it, rather than at cross purpose to it. In addition to these biological changes that needed to occur to allow for the development of speech, the authors argue that there were six pressures against the development of culture: first, the need to control for noise and emotions in the open savanna; Second, the need to increase sociality and group solidarity through verbal communication; third, the need to increase coordination and instrumental action by group and through verbal communication; fourth, the need to expand the tool kit used by hominoids; fifth, the need to increase the capacity for symbolizing and totemizing; and finally, the need to increase the ability to see and evaluate self from the prospective of the other.…
Brain size continued to increase throughout the hominid line, some of the influencing factors, in addition to natural selection, for increased brain size are: bipedalism enabled early hominids to explore new environments, the use of simple tools and manipulation of resources increased cognitive ability, a higher protein diet promoted brain growth, and changing climates required new thinking methods in order to adapt and…
Understanding the Brain Sometimes you have to tell yourself, “I am a shark” and attack the day - Coach Campaign Understanding the brain is something that many people might find quite complex, especially if you are comparing it to a sea animal. However, they are not as complex as we think, for example, sharks and humans share the same characteristics and structures of the brain. Both species have a cerebrum located superiorly to the body along with a right and left hemisphere exactly like humans. The cerebrum performs functions such as encoding information and neural functions.…
What is “Brainology”? Brainology is the different type of mindset every person has. A growth mindset which people believe that their most basic abilities can be developed through dedication and hard work and a fixed mindset people believe their basic qualities, like their intelligence or talent. They spend their time documenting their intelligence or talent instead of developing them. My growth experience came from really small and continued on.…
Animals At Different Stages Of Evolution It has been proven that animals can change at different stages of evolution. This is, because of environmental change and isolation of groups of organisms and this is the main important role in evolution which has caused animals to change and is still changing. Environmental change is a change in the environment which an organism must adapt to survive. Change of the environment, can be really slow and take time, for example when mountains and deserts form and this will cause some organisms to die and may cause new species to evolve.…
When do kids become adults? A question that's frequently debated across the world, and for good reason too. The answers to this question impact when people are given certain responsibilities, greatly affecting the overall population. For example, if people were allowed to drive at the age of thirteen, we may or may not have more accidents. This would affect not only those 13 year olds, but everyone else involved.…
In The National Institute of Mental Health’s, “The Teen Brain: Still Under Construction” it is explained that the teen brain is still growing physically, intellectually, and hormonally. First, the teenage brain is still growing physically. It is getting larger and becoming more connected to its parts. This is evident when the author writes, “As the brain develops, the fibers connecting nerve cells are wrapped in a protein that greatly increases the speed” (1). The brain grows physically just like the rest of the body.…
Every brain grows and the most growth that the brain undergoes is through the teenage years. During the…
Still others believe that the reduction in brain size is proof that we have tamed ourselves, just as we domesticated sheep, pigs, and cattle, all of which are smaller-brained than their wild ancestors. ”(Discover Magazine) As we have evolved, the need for a larger brain, became less apparent. Over time, we learned how to store information in our brain and the way we applied ourselves to the outer world wasn’t needed as much. Meaning that in past times, humans hunted less and they learned to cultivate food.…
What is the brain and what functions does it have? The brain is an organ of soft nervous tissues. It has many functions. One important function is the intellectual capacity. The brain is the main organ in our bodies we use for learning.…
