Option
Here is the option for the question :
- Human
- Tree shrew
- Elephant
- Dolphin
The Answer:
And, the answer for the the question is :
Explanation:
Because of our comparatively large brains—a ratio of 1 to 40 suggests that our brains are rather huge compared to our bodies—humans have one of the most spectacular neurological systems found in the animal kingdom. Tree shrews, on the other hand, reign supreme in the mammalian kingdom due to the fact that their brains are ten times the size of their bodies. Tree shrews may seem like mice, but their higher brain functions are more closely related to those of primates in terms of their evolutionary history.
The tree shrew is a small, arboreal mammal that is native to the dense forests of Southeast Asia. It is known for having the largest brain-to-body ratio of any mammal, meaning that its brain is proportionally larger than that of any other species. This unique feature has made the tree shrew an important model organism for studying the evolution and function of the mammalian brain.
The brain-to-body ratio of the tree shrew is estimated to be around 1:17, meaning that its brain accounts for approximately 6% of its total body weight. This is significantly higher than most other mammals, including humans, whose brain-to-body ratio is around 1:40. Despite its small size, the tree shrew’s brain is highly complex and sophisticated, with a number of unique adaptations and features.
One of the most notable features of the tree shrew’s brain is its enlarged visual cortex, which is responsible for processing visual information from the eyes. This adaptation is thought to be related to the tree shrew’s arboreal lifestyle, as it relies heavily on its vision to navigate through the dense forest canopy. The visual cortex of the tree shrew is highly organized and contains a number of specialized regions that are dedicated to processing different types of visual information.
the tree shrew’s brain also contains a number of other adaptations that are thought to be related to its unique lifestyle and ecological niche. For example, its olfactory bulb, which is responsible for processing smells, is relatively small compared to other mammals, suggesting that smell is not as important for the tree shrew as it is for other species. The tree shrew’s brain also contains a number of specialized regions that are involved in processing auditory information, suggesting that hearing may be particularly important for this species.
The unique features of the tree shrew’s brain have made it an important model organism for studying the evolution and function of the mammalian brain. Researchers have used tree shrews to investigate a wide range of topics, including the neural mechanisms of vision, hearing, and cognition. By studying the tree shrew’s brain, scientists hope to gain a better understanding of the complex processes that underlie perception, behavior, and cognition in mammals.
