The origin of biology, like that of the other sciences, comes from philosophy, from which it was separated at the time of the Enlightenment. However, its modern conception developed after the essential findings of Darwin and Mendel, at the end of the 19th century. This is when the most relevant advances in evolution and genetics were made.
Throughout history, this natural science has been given the task of answering essential questions about the origin of life and its fundamental laws. In that sense, its study is fascinating and is the basis of many other sciences that feed on it to advance their own findings.
Biology is the science that studies all living organisms on the planet, from the microscopic to the largest. It encompasses all kingdoms: human, animal and plant. Each one of vital importance to preserve the world as we know it.
The importance of this natural science lies in the fact that it explains how life develops on earth, its origin, evolution and even its possible death. It is also in charge of studying the natural laws that govern life and how to improve it, collaborating with branches such as ecology, medicine or chemistry. Its theoretical principles feed many other important disciplines.
Biology is not a totally independent science, since it also feeds on other elementary sciences such as mathematics, physics and chemistry, mainly. Its study is based on the scientific method.
It explains the development of living organisms in the following way: Through a metabolic process, the internal condition of organisms is maintained in equilibrium, due to different chemical reactions of nutrition and waste. Likewise, there is a relationship with the environment, reacting to its stimuli.
Thanks to biology, crucial discoveries have been made in the history of mankind, such as the case of penicillin and vaccines, which have saved so many lives to date. Also, the future seems to advance thanks to molecular biology that contributes to the genetic modification of food.
For all these reasons and many more you should take a look at our collection of free biology books in PDF format. We know that you are passionate about this science that is indispensable to continue walking on this planet and, consequently, we wanted you to increase your knowledge about it.
1) Animal Biology Books
Animal biology is the science that deals with the study of what is called the Kingdom Animalia. This kingdom comprises all multicellular organisms. And which take energy through the digestion of food and also contain cells that are organized into tissues.
This is different from plants, which produce their nutrients from inorganic substances through the process of photosynthesis. Animals actively provide themselves with food. And they proceed to digest it in their internal system.
In animal biology, animal tissues are made up of different cells, which are joined together. Likewise, the extracellular matrix is formed through characteristic junctions.
2) Biotechnology Books
Biotechnology is defined as a multidisciplinary area, employing biology, chemistry and various processes, with great utility in agriculture, pharmacy, food science, forestry and medicine. The term was probably first used by the Hungarian engineer Karoly Ereky in 1919.
Biotechnology dates back to ancient times, when techniques for manipulating living organisms were already being used to obtain certain results, such as the production of wine or bread, the secret of which is fermentation by microorganisms, yeasts, known as traditional biotechnology.
However, with the development of various scientific areas, especially those related to the DNA molecule, they transformed the way of manipulating organisms, relying in part on recombinant DNA techniques, which led to the use of genetic engineering techniques, giving rise to modern biotechnology.
3) Botany Books
Botany (from the Greek botanē that means grass) is a science whose object of study is the kingdom plantae, comprising plants, fungi and algae. Botany is a part of biology, which is the science that studies all living organisms.
Core botany studies plants, fungi and algae in their composition, functions, development, location, adaptations, etc., but there is also applied botany that studies the possibilities of using these species as remedies, in cosmetic products or other uses.
The father of botany was Theophrastus, a disciple of Aristotle, who in the 4th century B.C. published the first works focused on the study of plants. Few advances were made in the following centuries. Perhaps the most outstanding figure in the field of botany is Carl Linnaeus, an eminent Swedish scientist of the 18th century who devoted most of his life to studying and classifying plants and animals.
4) Cell Biology Books
Cell biology is the science that studies the properties, characteristics, evolution, life cycle and interaction of the cell with its environment. Cell biology is also known as cellular biochemistry. Cell biology studies derive from previous disciplines such as cytology (the branch of biology that studies cells) and histology (the discipline that studies organic tissues).
Cell biology is essential for the quality of life of human beings. This is because its findings and research are decisive, for example, in preventing diseases such as cancer or Alzheimer’s disease.
It also helps to propose therapeutic alternatives to improve the repair processes of human tissues and organs, as well as to combat agents that cause severe disorders in living organisms, such as those that occur when bacteria or viruses appear.
5) Ecology Books
Ecology is the science that studies the relationship between living organisms and the environment they inhabit. The definition of ecology is simple but the object of its study is very complex.
It was Ernst Haeckel, a German scientist, who created the term ecology in 1869 in order to designate a name for the science that studies the relationship between living organisms and the environment.
In particular, it studies how the environment influences their distribution, quantity, biodiversity, behavior, the interactions between different species and the modifications they can cause in the environment. Its levels of study are at the level of organisms, populations and communities of populations that make up ecosystems and the biosphere in general.
6) Environmental Biology Books
Environmental biology is a science that studies the possible solution to environmental problems and fundamentally requires a broad knowledge and understanding of the basic physical, chemical and biological processes that occur in nature, for which it is necessary to have qualified personnel to face this problem that integrates almost all branches of knowledge and that should converge in an effort to achieve an adequate relationship between humans and their environment.
Environmental problems are analyzed from a broad biological perspective, with a comprehensive vision of the components of the environment, in such a way that environmental policies can be formulated based on research processes.
The life sciences have undergone an extraordinary development in recent decades, which has led to a great diversification of the fields of study. Specifically, environmental biology studies the relationship of biological systems (organisms, species, ecosystems) with their environment.
7) Genetics Books
Genetics is a branch of biology that studies how hereditary traits are transmitted from generation to generation.
Genes are the units of information used by organisms to transfer characteristics to their offspring. The gene contains encoded instructions for synthesizing all the proteins of an organism. These proteins are the ones that will eventually give rise to all the characteristics of an individual (phenotype).
Genetics takes on special relevance when studying the transmission of diseases. In the same way that eye color is inherited from parents to children, there are also diseases that can be transmitted to offspring, in this case we speak of genetic or hereditary diseases.
8) Histology Books
Histology is a branch of biology that studies the organic tissues of animals and plants in their microscopic aspects: characteristics, composition, structure and function. For this reason, its fundamental tool is the microscope.
The Italian Marcello Malpighi (1628-1694) is considered the founder of histology. It was this biologist and anatomist who detected living cells for the first time. Thanks to increasingly powerful microscopes, histology progressed throughout the 17th century and in the following years.
The results of histological studies are key to medicine and biology, both for understanding the properties of the organism under normal conditions and for examining the presence of pathologies, their evolution and possible diagnosis.
9) Marine Biology Books
Marine biology is the scientific study of all organisms and species living in the aquatic environment. It must be taken into account that our planet is made up of two thirds of water and there are millions of living organisms that live in this natural environment.
Marine biology is strongly related to oceanography, the scientific study of the oceans. Within oceanography we can distinguish geological oceanography, which studies the seafloor, chemical oceanography, which studies the chemical components of the oceans, and physical oceanography, which studies the waves, currents, tides and other physical aspects of the sea.
10) Microbiology Books
Microbiology is the branch of biology that studies microorganisms, both prokaryotes and viruses as well as simple eukaryotes, uni and multicellular. The organisms that are the object of this branch are those that are only visible under the microscope. Etymologically it comes from the Greek mīkros (small), bios (life) and -logia (treatise, science).
In the field of health and medicine, microbiology is of great importance since it is in charge of studying pathogenic microorganisms such as fungi, viruses, parasites and bacteria that can cause disease in humans.
Through microbiology, infectious diseases suffered by any patient are studied and thanks to it, the most appropriate treatment for each disease and patient can be determined.
11) Molecular Biology Books
Molecular Biology is the scientific discipline that aims to study the processes that take place in living organisms from a molecular point of view. The following definition of Molecular Biology can be found in the Human Genome Project: The study of the structure, function and makeup of biologically important molecules.
This area is related to other fields of Biology and Chemistry, particularly Genetics and Biochemistry. Molecular biology is mainly concerned with understanding the interactions of the different systems of the cell, which includes many relationships, including those of DNA with RNA, protein synthesis, metabolism, and how all these interactions are regulated to achieve proper cell function.
12) Physiology Books
Physiology is the science that deals with the knowledge and analysis of the functions of living organisms. By bringing together the principles proposed by the other exact sciences (physics, chemistry, biology), this discipline gives meaning to the relationships between the elements that give life to living organisms.
Through the scientific method and experimentation, physiology is able to understand how living organisms change within an environment and to establish rules that determine the behavior of matter and energy in the course of life.
Depending on the type of living organism, we can distinguish three major groups: plant physiology, dedicated to the study of the functioning of the organs and tissues of plants, phyto-physiology is part of this group of physiology and develops specific taxa of plants; animal physiology; and human physiology, which is part of animal physiology.
