We have created well thought-out collections for lovers of the natural sciences, including biology, of course. You will find here invaluable information. 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. Some branches of biology are: microbiology , biotechnology , marine biology , zoology , botany , genetics , among others.

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. 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.
