Biology is the study of living or once-living organisms.Looking further into the contents of research, the scope of research includes the molecules and organisms that make up organisms, and the environment surrounding organisms. Biology takes a somewhat different position from physics or chemistry, which constantly divides the constituent elements of a subject of study into small pieces and examines their fundamental properties. In other words, even if they are made of the same ingredients, it is impossible to predict what kind of activities they will gather for what purpose and in what form.

For example, even if the components of a concrete structure, such as sand, lime, gravel, and rebar, are perfectly grasped, it is impossible to predict whether they will gather to build a school or build a bridge. Most of the components that make up living things are also used in the same way. However, it is impossible to understand and predict why these molecules gathered there and performed such life activities, no matter how well they know their properties.

So, what makes the molecules work together to sustain life in this organism?Why did those tiny little cells come together to form a large creature like our body and sustain life together? It seems that there is no way to answer this question, even if it is clumsy, other than accepting the existence of God or explaining it with the theory of evolution. However, the existence of God is not the issue here.through evolutionTrying to understand the strange and enigmatic existence of living things is at the root of biology.

Earth's history is said to be about 4.6 billion years. Of course, we have not gone back to that time, but it is the result of estimating the age of the earth using various scientific techniques. However, the first traces of life appear after that about 1 billion years, so you can see it in fossils about 3.6 billion years ago from now. And after that, various creatures that lived on the earth and disappeared remain in the form of fossils. Why they appeared and had to disappear is only speculation at this point. However, as scientific analysis technology has developed remarkably, it has been found that the history of living organisms is written in the genes of living organisms, and numerous studies are still being conducted to unravel the secret.

In order to understand the evolutionary process of living things, it is impossible to know why the living things themselves evolved in that direction. You have to understand the relationship of the environment surrounding the creature.It could be a physiochemical environment or something made by other organisms or organisms. Even now, in order to understand life phenomena, it is always necessary to study the effect of the environment on living things.

Beginning scientists who have just entered biologyBiological researchers should always be familiar with the question “Why?”To study biology in depth, simply look at the lifestyles and structures of various living things and say, “Ah! Do not stop at the pleasure of discovering, “Is there such a thing?”, but why did it have this form? Why do they reproduce in this way? It is necessary to think about what advantages the form and function gave to the survival and evolution of the organism. Then you will be able to see many invisible facts and even the limitations and possibilities of living things.

<English version>

Biology is a field of study that researches living organisms and those that once lived. If you delve deeper into the subject matter, it includes the molecules that make up living organisms, as well as the environment that surrounds them. Biology takes a somewhat different approach than physics or chemistry, which continuously break down the elements that make up their research subjects to understand their fundamental properties. In other words, even if they consist of the same components, it is impossible to predict what purpose they will serve, how they will form, and what activities they will engage in.

For example, even if you fully understand the components of concrete structure, such as sand, limestone, gravel, and steel bars, you cannot predict whether they will come together to make a school or a bridge. Most of the molecules that make up living organisms are made up of the same materials. However, even if you understand the properties of these molecules, you cannot understand or predict why they gather in a specific place and engage in certain life activities.

Then, what made these molecules collaborate inside living organisms to sustain life? Why did those small cells come together to form large organisms like our bodies and live together to maintain life? There seems to be no way to explain these strange and mysterious organisms without accepting the existence of God or explaining them through evolution. However, since the existence of God is not a topic of discussion here, attempting to understand these strange and mysterious organisms through evolution is fundamental to biology.

The Earth is estimated to be about 4.6 billion years old. Of course, this is the result of estimating the age of the Earth using various scientific techniques, not actually going back to that time. However, the first trace of living organisms appears in fossils about 1 billion years after that, about 3.6 billion years ago. After that, various living organisms that lived on Earth have left traces in the form of fossils. It is only conjecture why they appeared and had to disappear. However, with the remarkable development of scientific analytical techniques, it has been discovered that the history of life on Earth is written in the genes of existing organisms, and many studies are still underway to unlock its secrets.

To understand the evolutionary process of living organisms, it is necessary to understand the relationship between the organism itself and its surrounding environment. It could be a physical or chemical environment, or the relationships with other living organisms or the environment they created.

Beginner scientists who have just entered the field of biology, as well as bio-related researchers, should always be familiar with the question "Why?" In order to deeply study biology, one should not stop at the discovering various life forms and their lifestyles or structures and simply saying "Oh! There is such a thing?". Rather think about why they have taken such forms and why they have chosen to reproduce in such a way. It is necessary to think about how their form and function have provided advantages for their survival and evolution. Then, one can see many hidden facts that were not visible before, as well as the limits and possibilities of organisms.
