Human eyes are complicated, powerful organs, but there are some animals that beat us to the punch when it comes to vision. While it is almost impossible to conclusively rank which animals have the best eyes, because eyesight encompasses such a broad spectrum of attributes, we can look at how some animals have exceptional vision when compared with that of humans. While good eyesight is heavily influenced by the unique needs of the creatures in their particular habitats, it is a safe bet to say by human standards that a falcon has the best eye sight of any animal. Eagles and other birds of prey are kings in the animal kingdom when it comes to their visual acuity.
Prey animals, because of this, are capable of seeing details from a far greater distance than we are. Some animals see more colors than humans; others have superior vision, even under water; and yet another group of animals uses a variety of adaptations that enable them to move around the world at night.
We keep our eyes in the front of our faces, as do predatory animals, whereas predatory animals generally keep their eyes to the sides of their heads, to prevent predators from creeping up behind them. Shark eyes are a variety of shapes and sizes, but despite that, sharks and humans have many qualities in common when it comes to eyes.
With all those eyes, one would think that they are far better than humans at seeing things. Adult giant clams see the world through a few hundred tiny pinhole eyes that line the edges of their squishy bodies. Eagles are capable of seeing about eight times farther than humans, which allows them to detect and hone in on a rabbit or other animal about two miles away.
Although the owls eyes big eyes cannot move or roll as much as humans eyes, owls can turn their heads almost around, which allows them to see in 270 degrees of range without moving their bodies. Because the iris is adjustable, owls are able to see in daylight as well (unlike other nocturnal animals, which are able to see well only in the evening), but their vision is a bit foggy, and they cannot see colors very well. Taller daytime hunters typically have forward-facing eyes with circular pupils, whereas smaller animals such as cats, snakes, and foxes, which hunt both daytime and at night, have vertically-slit pupils, which helps smaller animals such as cats with depth perception, as well as with night vision.
The human eye can swivel, but at any given time, only looks one way. On a clear, moonless night, it could even pick up on a hitter striking from 50 miles away.
If we could see what an insect can, our eyes would be capable of seeing much finer details, since the human eye has acuity that is approximately 100 times better than that of a better compound. That means that what means that a person can see just fine at 75 feet is something a dog could make out at about 20 feet. The human eye can make one million simultaneous impressions, and it can distinguish eight million different colors.
If humans saw colors as hawks see them, we would see the world in an even brighter light; bright colors rendered in a staggering range of shades. The little creature that has the best color vision of any living thing in the world (as far as we can tell) is the Bluebottle butterfly.
Humans have amazing motor skills too, being the best hurlers by a long shot, anywhere in the natural world. Modern humans are Homo sapiens, and the intelligence of our species sets us apart from all other animals. Each defines a different way to say we; each kind of saying we defines a different community, and we are found within a variety of communities. The distinctive trajectory of human brain growth has made significant contributions to cognitive and language abilities in modern humans.
These modern humans-specific cognitive and language adaptations seem to correlate with the expansion of the neocortex and associated structures. Anatomical and molecular changes that may relate to increased metabolic demands on and increased synaptic plasticity in modern human brains have also been identified. Given the drastic differences in behavior between contemporary humans and other animals, one would reasonably expect similar marked changes in brain organization.
To make matters worse, since detailed studies of the neural anatomical organization between humans and apes are scarce, many unique features of the human brain are presently hidden from view. All eyes operate by the same principle–focusing light on to the retina, and translating the resulting picture into neural signals in the brain–but depending on what the animal has to do to survive, different adaptations emerge.
Humans are also capable of improving their vision when they suffer from a visual impairment, which is not true for any other animal. First, we have what is called binocular vision — we can focus both our eyes on one object. Modern humans ability to coordinate our hands and eyes finely is the result of long-term selection on visual guidance reaching abilities of primate stems (Cartmill, 1992).

What is unclear is how long the Party leaders will stay in power, and what this means for contemporary Chinas future, and for the world. Alfred Woo, who covers Xi for Chinese state media in Fujian, a province in the north of China, recalls that party leaders were soft-spoken and not visible, saying that they were less forceful than they became when they were the countrys leaders.
