Who am I?
That we can love someone is so peculiar to us that over the question as possible, we usually do not think. I, therefore, believe that it will be a good start for us if we look at who we are and where our ability to love comes from. In the following chapters, therefore, for a moment, let’s look into the world of biology.
The problem of where things come from was once theoretically solved by Aristoteles bodies. He realized in his undoubted genius that the question about the cause of the existence of things can even be offered four different types of answers: they are professionally called causa materials, causa formalis, the final reason and final reason. For example, the cause of the existence of a chalice is silver (causa material is), its shape (causa formalis), the one that processes silver (causa efficient), and its use in the Holy Mass (causa finals). The chalice would not exist without material, without silver. He wouldn’t be even if a skilled craftsman working with silver did not mold into a goblet. Nor would it exist if there was no need for worship. To the question: Who am I? I can answer from the perspective of physics and biology, for example, as a building block of atoms, a being composed of dust, five billion years old, and of gases from the time of its origin in earth, I am a community of cooperating cells.
Similarly, the question of love is answered by biology by pointing out
the body’s chemistry and the evolutionary past. Although these answers are truly wild, it is still necessary to realize that there is only one naturalist of symposium speakers. Physics and chemistry are, in the Aristotelian vision of things, only responding to the case of materials. In the limbic system of ours the brain is undoubtedly the confidential material basis of our feelings, but it’s not the whole story.
Neurons, cells of the nervous system, can talk to each other, sending impulses. Interestingly, the individual motivation, short electric discharges, are always the same magnitude: either, or they are not; zero or unit. The fact that you can now read this text, our perception of music, touch, the warmth of the human body, the smell of flowers and the taste of them, as well as the experience of anxiety, love, pain, the whole memory, fantasy and the ability to create art are the same nerve impulses of the same size bone. The fact that we perceive them once as toothache and sometimes as Schubert’s Improve depends on which areas of the brain and in which volleys and patterns these electric discharges arrive. Between the two cells, the electrical impulse usually changes to a chemical momentum for a short time. The chemical then either supports or prevents the electrical “ignition” of the next cell. The brain’s nerve cell receives impulses from many other cells at one point, and according to the sum of all, it then sends its impulse to other cells or does not send. This is how the human brain works. Even in the most conscientious anatomical research, we find nothing but cells, an average of five to ten million neurons per cubic centimeter of the brain, interconnected and receive and transmit impulses.
Biochemists have even found that the processes in the brain in a state of love are comparable to the processes in the brain of a drug addict after drug administration. But the claim that love is chemistry and that man is nothing else like a mechanical toy, a device to replicate its genes will hit to the frontier of biology, to the wall that delimits the natural space in ladies who explore nothing but matter and energy. For to understand what a person is, we must look to other universes than just the world of neurophysiologist and molecular biology.
Behavioral genetics provide us with a significant finding: Genes determine not only the visual material in our body – what color we will have. Eyes, where the organs will be located in the body and what the overall architecture of the body will look like – but they also stand in the background of our behavior, our actions, of our deeds. And as we will see below, genes are also behind our psyche.
The influence of genes on behavior is one of the most mysterious components of biology. When the spider weaves its web, it takes approximately 1,400 movements. And he doesn’t have to learn his art: everything is written in his genes, and so without ever seeing his parents at work, right after for the first time, the network will play accurately and without error. How can movements be recorded in genes?
Most insect species will not experience their parents and will never see their children: the new generation hatches in the spring, when the parental population is already dead. The whole complicated art of survival of locusts, beetles, and butterflies must be in some way already in the genes; it must be somehow already contained in the zygote, the first cell from which their bodies are formed. It must already in some way have information on what food looks like, what the reproductive partner looks like, and how to avoid enemies.
Swallows are moving south in the autumn to Africa. However, the first to fly is the young, born in that year, the old ones to follow them later.
So parents can’t show their children how they do it for the first time in the day. The entire download route and its direction must be somehow in their genes, and must have been in them when their body was made up only of the first cell’s zygote. It isn’t easy to imagine how they are all properties and body shapes of the swallow inscribed in its genes. In this, the first cell also hides a flight command to the south, and that in addition, it must be timed correctly and leading in the right direction to the right African zigzag; mysteries are still unsolved.
After hatching from eggs, eels must be assembled – so to speak, spa – three long years to travel alone back to the mouths of European rivers. Eels do not know the geography and do not know what the planet looks like. The eels we learn from our rivers lie far in the ocean, up to
the Sargasso Sea off Bermuda, more than 6 000 miles away.
The fertilized egg must therefore already contain instructions for a long and challenging journey home by the sea, to rivers where the eel has never been before – and also the information that at the end of life, it is necessary to swim back to the Sargasso Sea. The American rodent Diplomas orders’/ 7 (in Czech – as well as in Slovak) – it is called and reminds our mouse, a little) when he hears the purring sound of his the main enemy of the rattlesnake, thanks to its extremely well-developed hind legs, will make a reflexive long jump backward. The jump can be up to two meters long! Jumping at the crackling sound, Diplomas doesn’t have to learn from his parents. It is somehow written in his genes – there is no time to learn in nature; the only mistake is death. So, what the command “jump immediately” in a crackling sound can be written in the genes back! “without this individual ever bitter before the sound was heard, no one knows. Evolutionary biologists believe that there are many types in our species as well, behaviors are written in genes.
Much of our behavior is innate: for example, even a newly born blind child can smile if he wants to show satisfaction and frown when he shows his will. There is no culture in the world in which a smile is a sign of hostility. Thus, the innate ability to smile must be hidden somewhere in our genes. Outside running, chimpanzees can smile as well as they can kiss and touch your hand in greeting, albeit a little differently, how we shake hands. Just like a newborn does not have to
learn to smile, he doesn’t even have to know to look for swaying head movements in mother’s breast, he can do it from birth, and he can also suck – all those abilities are somehow rooted in his genes. But natives can firmly press the offered finger without learning, and even the strongest gripping reaction will be evoked by fur or anything hairy. Our ancestors probably wore cubs hung on for thousands of years, fur, as our closest relatives still do today. Now firmly to hold was therefore once necessary for the young. A similarly swaying movement is probably a sign to the child that everything is fine. Maybe that’s why a stroller walking on uneven paving or cradles has such a calming effect on children – we adults can imagine the most pleasant way to sleep.
This genetic behavior is ancient and originated in an entirely different context, such as our cities and skyscrapers. With our genes, we are probably armed to respond to significantly different ones However, in addition to genes, it affects us and all other organisms and our environment. Genes are the architectural design of our body and our administration; they are the project of the house to be created. In addition to designing, however, for the construction of the place you’re necessarily building materials, money, company, types of bricks and panels that are currently in stock. From one project thus, depending on the builder’s possibilities, several impressions can be created, and if a shortage of building materials, artisans must improvise. We would teach scholars about the norm of reaction. Japanese bonsai is an excellent example of how an organism is affected by the environment you grow. The usual tall would grow in nature tree from the same seed from which the gardener grows bonsai. If we plant some species of plants from rugged mountains to fertile lowlands, we are surprised by their high growth; We also know that we will see a much larger harvest for well-fertilized soil. Thus, not only genes but also the environment affect what the organism will look like. The genes of our hunting-gathering ancestors even explain our shared inability to lose weight. It is assumed that there was a moment of surplus in the hunting and gathering period, foods alternated with long periods of shortage. One of the modern hypotheses thinks that we overcame a period of hunger. The body sets itself up for what survival regime when carefully considering whether to release the calories obtained. A similar phenomenon may occur in people who are starting to lose weight: the body detects the beginning of a period of hunger and switches to a saving mode. The more we try to lose excess pounds, the more we will fight for calorie savings. Maybe because our cures part ends and infamous-genes did not notice enough food in our Euro-American population.
Situations like the ones we encounter in cities. After all, ours several million lasting existences just about the last few we have been living in homes for a thousand years, and our genes have almost certainly not yet adapted. We feel dizzy when we realize that some genes are in us
more than three billion years old, and that they are being handed over unchanged from one generation to the next across all animal species!
