Like tigers, lions, and other large carnivores, our eyes are forward-facing, which means we can see the area ahead of us to track and hunt our prey.
Are human eyes evolved from predatory eyes?
The evolution of human biology is a long and complex process involving hundreds of millions of years and many different types of organisms.
During this process, our human ancestors also went through many evolutionary processes. During these processes, the development of the human eye also undergoes many changes.
The two eyes growing on the face are the result of a long evolutionary process.
The eyes of people growing on the face are the result of a long evolutionary process. It is also the best way to adapt to the environment. If the eyes are in a high position on the body, they can see farther, which is beneficial for finding food and detecting enemies. To see much, to know widely will promote the development of human intelligence.
Evolution of the biological eye could have originated from primitive organisms around 500 million years ago. The creatures of the time were single-celled creatures with no senses or eyes.
Over the millions of years that followed, these creatures began to evolve gradually, undergoing many changes, including the appearance of the eyes.
The most primitive eyes are simple photoreceptors that perceive light and send these signals to the brain for processing. These light-sensitive receptors are first formed from single cells and gradually grow to form the complex structure of the eye, including the lens, retina and iris.
The front eye also has its cause.
The front eye also has its cause. The human foot advances, if there is an obstacle, it will go around; Two hands that are used to doing things in front also require both eyes to look in that direction.
In the history of human evolution, we have also undergone many changes. In the beginning, our ancestors were very primitive monkeys. At first their eyes were very primitive, only able to perceive light, but over time they evolved into the complex eye structures we have today.
Compare human eyes and predator eyes
Like tigers, lions and other large carnivorous mammals, their eyes are turned forward, that is, forward. they can clearly see the area in front of them to track and hunt their prey.
Unlike other prey such as sheep, rabbits, horses, …, their eyes are often directed to the sides, so that they can simultaneously observe their surroundings, in order to increase their vigilance, to escape attack by predators.
The two eyes in front of you can concentrate on observing and manipulating whatever is in front of you.
Laying eyes in front of you can focus on observing and manipulating everything in front of you, avoid inconsistent gestures (left and right), increase the stereoscopic sense of the picture of things, can be beneficial to judge near or far objects. This is extremely important in the competition for survival.
However, the human eye is different. The human eye is also forward focused, which means we can see the area in front of us clearly.. This is certainly a favorable evolutionary trait, as it allows us to see and manipulate more precisely during hunting and other activities.
Why did humans evolve to have predatory eyes?
So why did humans evolve to possess predatory eyes? This question has not yet received a definitive answer from scientists. However, several theories can explain this phenomenon.
The first hypothesis suggest that the evolution of the human eye is linked to the hunting activities of our ancestors. Millions of years ago, our ancestors began to hunt big game, which required them to be able to see exactly where their prey was.
So, over time, our ancestors developed forward-facing eyes for better tracking and hunting.
Under these environmental pressures, the evolution of the human eye may have been affected
If we have one eye on the left, one eye on the right, or one eye in front, one eye behind, human vision will be enlarged, but it is impossible to focus one’s attention. If you look carefully, you can. We do not see the stereoscopic image of objects, which prevents us from distinguishing whether the object is far or near.
The second hypothesis Our ancestors experienced many environmental stresses during their evolution. Under these environmental pressures, the evolution of the human eye may have been affected, leading to evolution toward possessing predatory eyes.
This may be because focusing on the eyes can make us more sensitive to the environment of our ancestors for better adaptation. For example, when hunting large animals, humans need to be able to see the animals from a distance in order to better track them.
Final, There is another theory about the evolution of the human eye that involves changes in the eyes of our ancestors when they evolved from tetrapods to vertically moving animals.
Since the eyes of upright animals require greater visual precision and greater depth perception, the human eye has gradually evolved to possess focusing properties.
Evolution of the human eye is a long and complex process involving the environment and the behavior of our ancestors. Although our eyes are forward facing, they are not necessarily the evolutionary product of predatory eyes.
