Monkeys and apes mainly see as humans do , as they are trichomats, so monkeys there can be up to six different types of color blindness or vision. As with their human cousins, color blindness is more common in males than in females.
Many birds can see differently. Pigeons , for example, can see literally millions of different hues and are thought to be among the best at color detection ability of any animal on earth. They have many more cones than humans in their eyes, thus accounting for the ability to see seven spectral bands.
You can mix bird sades with small plastic and other metal grains that all same size and you will see the pigeons pick the seeds faster with out trouble , because they can detect the bird seads colors or carbohydrates and grains. Human really on touch and test or smell. Cats and dogs do not have strong vision. They rely on scent and sound
primarily as their sensory detection. Cats in particular have weak vision than dogs. Dogs can sometimes tell the difference between yellow and blue, for example. Most cats can only detect a little color, and are best at focusing on one object narrowly (for hunting). But they do have better night vision than humans. Both dogs and cats have better perspective and depth perception, due to the placement of their eyes, than human beings do. Humans are limited . They can make war and kill the animal for game and trophies but they have lower anatomical abilities than many animals.
Snakes have two sets of eyes. One set is the normal eyes that you see. and they detect color quite But they also have vision pits that detect heat . and “see” living creatures like an infrared detector.
There is no getting away from a snake once you’re spotted. That closed door won’t help. Luckily most snakes are more likely to retreat than attack.the best thing is t hid in a fridge or cold area , use ice on snake or use fire distinguisher or any cold drink. Insects; Because of segmented eye structure, many insects see objects very differently from what humans perceive. Insects are famous for their dot-like eyes, known as ommatidia. Some have as many as 30,000 lenses per eyeball. But perhaps most interesting is the dragonfly.
This insect’s brain works so rapidly, it perceives most movement in slow motion. Insects do see color, but not usually as clearly as other animals. Their vision assists them in detecting movement. That’s why they’re so hard to kill! To the human eye, a garden in bloom is a riot of colour. Flowers blooms for our attention, utilizing just about every colour of the rainbow.
But of course, it is not our attention they need to attract, but that of insects, the perfect pollinating agents. Human have so many limitations and thanks god they do, because if they do not have these limitation, The majority of humans will kill and destroy life.

But where is human race headed to? Are we going to remain just as today human beings or are we going to become something else? Are we going to remain immortal through digitizing out consciousness
By 2409, women will be .7 inches shorter (2 cm) and 2 pounds heavier (1 kg). (Opposite to the current trend of having zero figures!!)
So this means we are evolving? No one can actually say anything for sure. One can say that the above observation can easily be negated by appropriate dieting habits.
Evolution is painfully slow to observe.There might be a global man- made disaster like nuclear winter which can alter our lives drastically. May be we become resistant to nuclear explosion like cockroaches.
There are too many parameters. Too many things to be taken into account. Saying any one thing will be too much speculation. But just for a thought experiment let us continue.
But this argument does not hold water considering human beings evolved only around 5 million years ago and about 99.6% of time we didn’t exist at all.
Another argument is that human beings do not need to evolve because it is nature which drives evolution. Species evolve so that they can adapt according to nature. But humans have now technological power to make nature adapt according to changing human needs (If not now, then maybe in a few hundred years).
Another claim is that evolution has not stopped and it is happening. After all in a confined group, it just needs a very very very little mutation for one species to evolve. Neanderthals and homo sapiens differ in their gene sequence by less than 0.004%!!
Note:Neanderthals never changed to Homo Sapiens. We are “cousins”; we share a common ancestor. It was initially believed our common ancestor lived 300,000 to 800,000 years ago, mostly likely Homo Heidelbergensis. However, some new evidence was found recently that may change this to about 1 million years ago, or even a little more than that.
10000 years ago one mutation in herc 2 gene led to blue eyes. Every male Olympic power athlete ever tested carries a 577 R genotype (So everybody can’t be an athlete?
We still have the ability to select who we mate with, and our choice is largely determined by cultural factors. For example, we value high intelligence, toned physique, large breasts etc. If these desirable traits remain somewhat constant, it is possible that they will lead human evolution
Humans may split in to 3 .
It is also possible that human beings may get evolved into sub species. This can result from two causes:
People would become choosier about their sexual partners, causing humanity to divide into sub-species. The descendants of the genetic upper class would be tall, slim, healthy, attractive, intelligent, and creative and a far cry from the “underclass” humans who would have evolved into dim-witted, ugly, squat goblin-like creatures.
Moreover rich people will move toward artificial evolution by deciding the genome sequence of the just conceived baby. This will create kind of split between upper-class, dominant population and a lower-class, genetically oppressed population
The most common colour skin tone used to be white, now its brown and continuing into the future, with more racial mixing, our skin would probably take on a grayish hue.
Chins will become smaller from the effects of not requiring strong jaws to chew and eat processed foods. Heads will become larger to accommodate a larger brain.
So you could expect a large oval shaped head.
Continuing with the genetic influence of inter racial mixing, we’d probably adopt the same slanted eye shape as the Asians who currently make up a vast majority of the world’s population.
As the sun starts burning out, and the moon running away from earth the eyes will grow larger to allow more light in.
If transportation remains relatively easy, cheap, safe and accessible- you’ll continue to get a lot of genetic mixing. This is especially true in America where the vast majority of immigrants are from Latin/South America , China , South and East Asia.
You’ll see this in Europe ,These immigrants will end up intermarrying at some point with “white” people leading to browner people going forward.
They are still American or French or German- but browner. Culture and skin tone don’t have hard and fast correlations.
I don’t think man will be taller. Diminishing returns to survival and mate selection after 5’6″ or so.
I don’t think man will have a larger adult head, though C-sections probably are letting a lot more large headed babies be born and allowing a lot more thin hipped mothers to survive child birth.
Man doesn’t need to be father because medical innovation may lead to great strides in nutrition, weight mgt, calorie consumption and absorption.All of this will depend on whether or not we develop the technology to genetically modify ourselves or not.
Assuming technologically we change, we will be constrained more so by our technology than anything else. At some point, it is likely that we will become cybernetic or even completely robotic. The reason is because being electronic does have significant advantages over being organic, such as greater durability, and the potential for greater longevity.
For those saying that we will have bigger heads, I actually don’t think so. The human brain has been shrinking for the past 20,000 years.
And if we do not genetically modify ourselves or become cybernetic? Well, our bodies evolved for most of the history of our species for a Paleolithic lifestyle and we’re optimized for that. It takes about 20,000 years to make changes, so I imagine that we will adapt more for a “civilized” type of life.
The other interesting thing is our low infant mortality. Remember, in most other species, most infants do not survive to the age to reproduce. As late as the early 20th century, infant mortality was very high. It still is in many parts of the developing world. This was evolution at work. Traits that did not facilitate the long term survival of the species were eliminated. Our modern technology changes that. That could have some interesting effects. My hope is that someday, we will be able to eliminate low infant mortality and that emerging medical science can cure those with genetic illnesses.
What’s maybe more interesting is how will culture change. Civilization has developed only in the last 5000 years and the rate of change is getting faster and faster. Computers, obviously are extremely new and already central to many lives. Most importantly, cultural and technological impact has reached a point where it will effect and change our lifestyles much more quickly than evolutionary forces. This is turn will have its effects on human biological make-up.
Brain-computer interfaces — this is possible now. Without a doubt we will soon be controlling machines with our minds. Soon after machinery will become integrated with our bodies.
Genetic manipulation also opens the door to a world of possibilities. One, people design their children – this will likely be possible to some extent within the next 100 years (whether permitted will be another question). It should be permitted , religious people and nerdy politician should not control science.
The further possibility is of literally designing new human species. It will become difficult to understand what is human and what is not. Human’s might “evolve” into something entirely different.
THERE ARE 99 CONSTELLATIONS . One day science will prove that I am correct about it.
One cultural idea that has been proposed is the “modern caveman” theory. The central concept is that cavemen lived more or less automatically, though they were similar biologically to us; they were motivated by their desires and did not give much thought of worry to their lives outside circumstances. As technology solves human problems, we may reach a point where humans return to this state of near automatic living — no need to work and so a life of leisure in technological interaction.
In conclusion;
Species do not undergo evolutionary change for the sake of it. For evolution to occur, there has to be a driving force such as a change in the food supply, a change of climate, or the arrival of a new predator or disease, Massive war and famine , massive heat or cold weather.
Homo Sapiens is unique in that, as omnivores who can cook, we can eat almost anything; as tool-users, we can construct shelters from inclement weather, and clothe our naked bodies to keep warm. It is difficult to imagine an ecological change drastic enough to start evolution’s wheels grinding in our DNA. Indeed, thanks to our extremely slow rate of maturation, any sudden ecological change might be more likely to drive us to extinction than to evolve. We are already so adaptable that any changes which might force evolution would in all seriousness be so drastic that the glacial pace of evolution would be too slow to save our particular branch of Darwin’s tree. Eyes and retina will change, our hair and skin color will change, our head and Height will change too.
It might, therefore, be more fair to say that he humans of the future will look like fossils. We’re all doomed by the enormous environmental demands we make of our planet.
