11. Shades of Green

-

In the long process of evolution, the evolution of biological morphological structures and physiological functions is usually caused by changes in the environment. The ancestors of giraffes had short necks and short horns. They lived in the African savanna zone. Most of the trees were umbrella-shaped. During periods of food scarcity, deer that could eat leaves from higher places survived. According to Darwin's theory, survival of the fittest is the law of biological evolution. In the derivation process, only genes that can reflect survival advantages are more conducive to continuation. Deer with short necks are gradually eliminated, and their necks slowly become longer and longer. So are the legs. The same evolutionary logic applies to humans walking upright. Standing on two feet not only provides a wider field of vision, but more importantly, freeing the hands is conducive to the use of tools for hunting, gathering and even defense.

Similarly, visual sensitivity to color is also closely related to the environment. The visual system will produce compensatory responses as the external environment changes. That is to say, when some tissues or organs are damaged or their functions are weakened, resulting in structural or functional imbalances, The body's mechanism will replace and compensate for the deficiency by mobilizing other tissues. For example, the hearing and touch of congenitally blind people are much stronger than that of ordinary people, because after their visual cells are reduced, the number and volume of auditory and touch cells will be larger. Changes in visual pigment molecules also change with the environment. While it needs to be more sensitive to changes in certain colors, it is correspondingly slower to others.

In ancient times, in order to protect themselves from wild beasts and stay away from wet ground, humans developed from cave dwellings to nest dwellings. They walked out of caves and began to build residences on trees with branches and canes, so that the living environment was completely covered with green. Humans must always be alert to their surroundings when living in the jungle and obtaining food. When there is prey or danger, leaves or grass will be disturbed, and the intensity and frequency of light reflected by green plants into human eyes will change. Shadows appear, thus making the eye more sensitive to shadows in green light. The shadow may be hidden prey or other dangerous animals. If you are not sharp enough and your reaction is slow, it will be difficult to catch the prey. If you are not the prey, you may be hunted by a stronger predator. Only being sensitive enough to shades of green is beneficial to survival, so having genes that are sensitive to shades of green is easier to perpetuate. In a jungle environment where the weak can prey on the strong, those genes adapted to the competition for survival can be preserved and continued, and animals evolve accordingly. So the shades of green are often the real danger

Sunset, heartbroken people in the horizon. The car rushes into the sunset, the afterglow shines on the face, glowing with light. The life of the pink girl has always been golden. Looking at the road leading to the sky, I am drunk, drunk. The sunset is as passionate as fire. The sunset is waiting at the end. I am intoxicated. The sunset here is so beautiful and intoxicating, which makes people feel comfortable and comforts the soul. There are too many traces of carving in the sunset between high-rise buildings. No matter how beautiful it is, it still looks cold. The real beauty is always nature.

Then they entered a service area to refuel. Looking at the numbers on the display, Alang couldn't help but sigh:

"Oil prices are so high, everything is going up"

"Is it expensive?"The pink girl took out her mobile phone to pay, while her classmates stayed in the car.

The pink girl's understanding of life has certain limitations. She doesn't know what the price of gas should be to be considered expensive. For her, no matter how much it is, it is not expensive. She She had never had much idea about money, and she couldn't understand A Lang's feelings. The kind man in front of her but with some anger in her heart made her more curious about what his life was like.

After refueling and entering the rest area, A Lang started from After coming out of the toilet, I was smoking while waiting for them. At this time, an Audi A6 parked next to the Mini car. A man and a woman got out. After looking around, they moved their shins beside the car, as if they had driven a long way. Surrounding There were many empty parking spaces, and the Audi was parked next to their car. Alang had to pay attention, and the smoking atmosphere was ruined. The girls felt a little uncomfortable when they came back from the toilet, so they got in the car directly. Alang threw the cigarette butt into the garbage In the box, I quickly got into the car. Just as the car started to move, I heard the sound of the car being slapped, and at the same time, a woman's voice came:"Ouch... Ouch……！"

A Lang stopped the car and got out. Under the shadow of the setting sun, he saw the woman who had just moved sitting on the ground with her back to the car. A Lang asked:

"What's wrong?"

The woman should be not much older than Alang. She has long wavy hair half covering her face, a white top, tight pants, and black high heels. She looks like a certain type of fashion, and she also looks like the proud sister-in-law next door.

"Your car hit my foot, what's wrong?"The fashionable sister-in-law raised her head, her eyes hidden behind a pair of big sunglasses, and complained through the mask.

The man was about to go to the toilet after moving a few times. When he passed by A Lang, he glanced at him and heard the fashionable sister-in-law's cry. Turning back halfway, he was older. He had a flat head and a round face. He was wearing a pair of small sunglasses. He was not tall and his slightly fat body was wrapped in a khaki high-end casual suit. He seemed to be a successful business person with a bit of a big brother look..

The flat-headed brother immediately squatted down and carefully took off the fashion sister-in-law's shoes:"Baby, where are you pressed?"

"Little toe... Ouch... be gentle, it hurts, it hurts……"The fashionable sister-in-law kept shouting
