Discussion Overview

The discussion revolves around the factors that contribute to intelligence differences among species, particularly between humans and animals, as well as among humans themselves. It touches on biological aspects such as brain size, cerebral folds, and oxygen intake, and seeks to understand the underlying reasons for human dominance in intelligence and scientific advancement.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant notes the evolution of jaw structure leading to increased brain size but questions why this correlates with intelligence and human dominance.
  • Another participant emphasizes the importance of cerebral folds in addition to brain size, suggesting that this is a critical factor in intelligence.
  • A different participant expresses confusion about what specifically makes one human smarter than another, focusing on biological factors like oxygen intake and blood flow.
  • One participant proposes that brain size alone is not sufficient for intelligence, arguing that the proportional size of the brain to body and the degree of cerebral folding are more significant.
  • Another participant expresses frustration about the lack of responses in the forum, questioning the effectiveness of the educational department for such inquiries.

Areas of Agreement / Disagreement

Participants express differing views on the factors that contribute to intelligence, with no consensus reached on the primary determinants. Some focus on brain size, while others highlight the importance of cerebral structure and proportionality.

Contextual Notes

Participants reference various biological aspects of intelligence without resolving the complexities involved, such as the definitions of intelligence and the implications of brain structure differences.

I am aware of the jaw evolution that caused our brain size to increase but I believe there are animals that have bigger brains than we do like extincted dinosouras. What I don't get is what makes one smarter than the other? How did we become the dominating species? How did we accelerate so much in science? Please try to answer quickly b/c I have an essay due on monday.

I am not only talking about humans vs animals, but also talking about humans vs. humans. What makes one humans smarter than other? Although I know that there are several kinds of smartness, I am talking biologically. For instance, I know the bigger the brain is and the more oxygen a person gets, the smarter he becomes.

Shame one you. If this is a class, you've no doubt had discussions, have a textbook, and should have been awake.

Brain size is one aspect, but cerebral folds is another. Try to pay attention in class.
 
Alright, I researched about it and I got it. There is one thing though I still don't get, what makes 1 human smarter than another? I am not talking different types of intelligence, I am talking about stuff like taking more oxygen, greater blood flow, etc.

Btw, these questions are not coming from a science class, but rather an english class for an essay. I do pay attention in class.

The answer I found to why we are smarter than animals is that the size of the brain doesn't matter, but what matters is the proportional size to the body and how much folded the cerebral is. Well, if their brain cells were bigger than our brain cells, that would make sense, but that is not true. Hence the only conclusion I can come up w/ is that there brain is smarter than us but b/c our cerebral is folded so much, it overcomes that. To be clear, if our cerebral wasn't folded and their wasn't folded at all either, then they would smarter than us. All I said though is an effort to understand the truth b/c I am a noobie so can someone proofread my reasoning?
 
You see, this is why I posted in the Brain department, what good is the educational department if no one answers?
