Elephant Gereotypes

In the article “You Can Grow Your Intelligence”, the author discussed a couple of studies that proved not only can your brain grow, but so can your intelligence. It mentioned facts pertaining to the weight of the brain, connection between nerve cells and how it affects the overall intelligence of a species. One of these studies included animals from different environments being tested on their intelligence. According to the study, the animals that were held in captivity and lived alone were not only found to have smaller brains than the ones who lived in a challenging environment, but had less communication between the brain cells that allows them to think strategically and communicate with others. The article claims this theory to be true

The human brain is a feat of evolution: it has allowed humans to have complex thoughts, conscience, build tools, create fires, and much more. Humans did not acquire this simply by chance. Evolution throughout our ancestral past has shaped and moulded the human mind to its state. The earliest of ancestors, including apes, had very small brains, but as evolution progressed, so too did the human brain. The rapid progression of human intelligence has been attributed to environmental changes causing humans to change with their surroundings for survival. This lead to the expansion of specific areas of the brain, vastly differing maturation of humans compared to our

Firstly, it is important to understand the evolution and development of human brain. An interesting idea is that our human brains are becoming smaller in size through evolution of time. It is commonly believed that more content requires bigger space. Let 's take an example. A bowl that needs to fit ten identical objects needs to be bigger to a bowl that only needs to fit five identical objects. Likewise, our human brain has continued to develop through evolution and has much more complex capabilities as well as content to carry since the birth of our species in the Stone Age. Now

“The first Cro-Magnon skull supported the theory that the brains have grown slightly smaller over the past tens of thousands of years. There are not any reasons supporting that Homo sapiens are less intelligent

Due to the anatomical correlation linking to the brains of both humans and animals it can be said that animals have minds and similar cognitive capacties to those of humans (The Economist,

Hi all, in topic 10 one of the subjects that capture my attention was "how our large brains are produced" (Bingham, Paul M., and Souza J. 2009). Human brain is around three times as large as that of our nearest living relatives, the considerable apes. General brain size is a decent indicator of cognitive performance in an assortment of tests in primates (Deaner R, Isler K, Burkart JM, et al. 2007, Reader S, Hager Y, Laland KN. 2011). Subsequently, theories clarifying the advancement of this momentous distinction have pulled in much intrigue. On the off chance that subjective advantages are various and predominant, it is conceivable that the vast majority of the variety in relative brain size among surviving primates is clarified by variety

Primates and cetacean have been considered by some to be extremely intelligent creatures, second only to humans. Their exalted status in the animal kingdom has lead to their involvement in many experiments which hope to gain a better understanding of the basis of human intelligence. These experiments coupled with analysis of primate and cetaceans brain structure has lead to many theories as to the development of intelligence as a trait. Although these theories seem to be sound, there is some controversy over the degree to which non-human studies can be used to infer about the structure of human intelligence.

Ten years ago, brain researchers thought they understood the complex components of the human brain. They concluded that all mammalian brains were similarly made, and that the number of neurons within a given brain corresponded directly to brain size. These previously held ideas upset Suzana Herculano-Houzel because they were based upon little scientific evidence. She found both cow and primate brains to be relatively the same size, yet primates displayed a higher cognitive ability. Likewise, if brain size was an indication of cognitive ability, certain animals with larger brains should possess higher cognitive abilities than humans. However, previous neuroscientists dismissed these contradictions by referring to the human brain as “special.” Examples like these convinced Suzana Herculano-Houzel that all mammalian brains were not similarly made. She inquired to understand why the human brain was “special” and not bound by

The largest animal on earth is the African elephant. They grow to be ten to twelve feet tall at the shoulders. They may weigh six tons. That is about the same as what a big truck weighs. African elephants have three traits. They have large ears, long curved tusks, and flexible trunks. Their big ears help the elephants to keep cool. They move their ears back and forth like a fan. African elephants also use their ears for communication. Happiness and anger are two feelings they show. Male and female elephants have curved tusks that stick out of the sides of their mouths. The tusks may grow up to eight feet long. The elephants’ trunks are used for many purposes. They use them for breathing, for sucking up water, for smelling, and

African elephant also known as (savanna elephant) are the largest mammals on earth. They are slightly larger than their Asian cousins and can be identified by their very large ears. The male and female both have tusks that they use to dig for food. Female elephants (cows) live in family herds with their young ones, but adult males (bulls) tend to roam on their own. Also they usually are ten to fifth teen elephants in one group. The genus name if the African elephant is Elephantidae.

“The brain has many parts that work together.” (Your Brain and Nervous System). The main part of the brain, the cerebrum is the biggest part of the brain. When you imagine the brain, a person would imagine a tangle of pink wires. That is only the cerebrum. It takes up 85% of the brain’s weight

In Stanley Coren’s, “Are Dogs More Intelligent than Cats?” the main question simply is, are dogs or cats smarter. Although the question is simple the solution is much harder to find. Different animals have different abilities so measuring the intelligence of a cat by having it move “from place to place, where speed is a measure of performance” (Coren) would not be logical. Since there is difficulty measuring an animal’s intelligence psychologists and biologists needed a new technique. The idea that the bigger the brain of an animal the smarter an animal is came into play. This had its flaws because this method claimed the “super geniuses” (Coren) would be whales who have a larger brain mass than human beings. Finally in the 1970’s, Harry J. Jerison created the Encephalization Quotient. The Encephalization Quitient or EQ is a method that calculates an animal’s brain weight to its body size. With this method it was found that dogs have a higher EQ than cats do. The social interactions and higher demands on domestic dogs make them in fact smarter than the cat.

In the article, “Ancient DNA Reveals Elephant Birds and Kiwi are Sister Taxa and Clarifies Ratite Bird Evolution”, the researchers discuss the relatedness of the certain ratites. Ratites are flightless birds that includes the two birds in focus, the elephant bird and the kiwi. The kiwi is a small bird that is about a foot and a half tall, while the elephant bird can be 6-10 feet tall. Topics they discuss about the relatedness of these two species ranges from previous theories, the dispersion of their common ancestor, and the evolution.

In defiance of people regarding others with big heads to be smarter, no evidence have been found to back up this theory. In reality, it dosent matter, such as the brilliant physicist Einstein had a smaller brain that didn't age normally in fact it was the same as a mid 20 year olds even though he was 77 when he died. also, the only parts of the brain used for thinking are the outer skin or cortex of the forebrain or cerebrum. The cerebral cortex is the thick layer of tissue with multitudinous folds. unlike the grain size theory it's actually the number and depth of the folds in the cerebral cortex that determines your intelligence, no matter the species it could be an animal or a human all that matters is the number and deepness of the

Conversely, other scientists disagree that brain size alone is the sole indicator of intelligence, preferring instead, the theory that the answers lay in the brains synapses and the way information is exchanged and gene duplication (DNews, 2015).
