It was used again in in a work entitled Philosophiae naturalis sive physicae: The first German use, Biologie, was in a translation of Linnaeus' work. The term came into its modern usage with the six-volume treatise Biologie, oder Philosophie der lebenden Natur —22 by Gottfried Reinhold Treviranuswho announced: The science that concerns itself with these objects we will indicate by the name biology [Biologie] or the doctrine of life [Lebenslehre].
Although modern biology is a relatively recent development, sciences related to and included within it have been studied since ancient times. Natural philosophy was studied as early as the ancient civilizations of MesopotamiaEgyptthe Indian subcontinentand China. However, the origins of modern biology and its approach to the study of nature are most often traced back to ancient Greece.
Especially important are his History of Animals and other works where he showed naturalist leanings, and later more empirical works that focused on biological causation and the diversity of life. Aristotle's successor at the LyceumTheophrastuswrote a series of books on botany that survived as the most important contribution of antiquity to the plant sciences, even into the Middle Ages.
Medicine was especially well studied by Islamic scholars working in Greek philosopher traditions, while natural history drew heavily on Aristotelian thought, especially in upholding a fixed hierarchy of life. Biology began to quickly develop and grow with Anton van Leeuwenhoek 's dramatic improvement of the microscope.
It was then that scholars discovered spermatozoabacteriainfusoria and the diversity of microscopic life. Investigations by Jan Swammerdam led to new interest in entomology and helped to develop the basic techniques of microscopic dissection and staining.
In the early 19th century, a number of biologists pointed to the central importance of the cell. Then, inSchleiden and Schwann began promoting the now universal ideas that 1 the basic unit of organisms is the cell and 2 that individual cells have all the characteristics of lifealthough they opposed the idea that 3 all cells come from the division of other cells.
Thanks to the work of Robert Remak and Rudolf Virchowhowever, by the s most biologists accepted all three tenets of what came to be known as cell theory. Carl Linnaeus published a basic taxonomy for the natural world in variations of which have been in use ever sinceand in the s introduced scientific names for all his species.
Although he was opposed to evolution, Buffon is a key figure in the history of evolutionary thought ; his work influenced the evolutionary theories of both Lamarck and Darwin. Lamarck believed that these acquired traits could then be passed on to the animal's offspring, who would further develop and perfect them.
The discovery of the physical representation of heredity came along with evolutionary principles and population genetics. In the s and early s, experiments pointed to DNA as the component of chromosomes that held the trait-carrying units that had become known as genes.
A focus on new kinds of model organisms such as viruses and bacteriaalong with the discovery of the double helical structure of DNA inmarked the transition to the era of molecular genetics. From the s to present times, biology has been vastly extended in the molecular domain. Finally, the Human Genome Project was launched in with the goal of mapping the general human genome.
This project was essentially completed in with further analysis still being published.
The Human Genome Project was the first step in a globalized effort to incorporate accumulated knowledge of biology into a functional, molecular definition of the human body and the bodies of other organisms.
Foundations of modern biology Cell theory Human cancer cells with nuclei specifically the DNA stained blue. The central and rightmost cell are in interphaseso the entire nuclei are labeled. The cell on the left is going through mitosis and its DNA has condensed.
Cell theory Cell theory states that the cell is the fundamental unit of lifethat all living things are composed of one or more cells, and that all cells arise from pre-existing cells through cell division.
In multicellular organismsevery cell in the organism's body derives ultimately from a single cell in a fertilized egg. The cell is also considered to be the basic unit in many pathological processes. Finally, cells contain hereditary information DNAwhich is passed from cell to cell during cell division.
Research into the origin of life, abiogenesisamounts to an attempt to discover the origin of the first cells.
Evolution A central organizing concept in biology is that life changes and develops through evolution, and that all life-forms known have a common origin. The theory of evolution postulates that all organisms on the Earthboth living and extinct, have descended from a common ancestor or an ancestral gene pool.
This universal common ancestor of all organisms is believed to have appeared about 3. Darwin theorized that species flourish or die when subjected to the processes of natural selection or selective breeding.Limestone is a chemical or biological sedimentary rock that has many uses in agriculture and industry.
Flux Stone: Crushed limestone is used in smelting and other metal refining processes. In the heat of smelting, limestone combines with impurities and can be removed from the process as a slag.
Biological processes involve changes in an individual’s physical nature. Examples of biological processes includes, brain development, height and weight gains, changes in motor skills, hormonal and changes occurring in puberty.
Nature refers to an organism's biological inheritance, nurture to it s environmental experiences. The "nature proponents" claim biological inheritance is the more important influence on development; the "nurture proponents" claim the environmental experiences are more important.
> Global Challenges. Our expertise and global reach help promote safety and health for the planet and its inhabitants. > Strategic Priorities Our focus revolves around Agriculture & Nutrition, Advanced Materials and Bio-Based Industrials. Since epigenetics acts as a conduit through which environmental factors elicit lifelong biological changes, it provides a molecular basis to suggest that nurture has a strong impact on biological functions and behavior, in some cases, perhaps a stronger impact than nature (genes).
