Dr. Kratz holds a PhD in Botany from the University of Washington. [15] Taoist philosophers, such as Zhuangzi in the 4th century BCE, also expressed ideas related to evolution, such as denying the fixity of biological species and speculating that species had developed differing attributes in response to differing environments.[16]. Over a dozen medical papyri have been preserved, most notably the Edwin Smith Papyrus (the oldest extant surgical handbook) and the Ebers Papyrus (a handbook of preparing and using materia medica for various diseases), both from the 16th century BCE. Lina D. BoredPanda staff. Then, Charpentier teamed up with American biologist Jennifer Doudna and the two scientists figured out how the RNA, DNA, and a protein called cas9 work to create a very targeted gene-editing system in the bacteria. Soon after the war, the “miracle drug” was used to treat infections in the general public, and the race to discover additional antibiotics was on. Ecology expanded rapidly with the rise of the environmental movement; the International Biological Program attempted to apply the methods of big science (which had been so successful in the physical sciences) to ecosystem ecology and pressing environmental issues, while smaller-scale independent efforts such as island biogeography and the Hubbard Brook Experimental Forest helped redefine the scope of an increasingly diverse discipline. New fields of biological sciences research emerged including Bioinformatics, Neuroscience, Theoretical biology, Computational genomics, Astrobiology and Synthetic Biology. In 1828 Wöhler showed that the organic substance urea could be created by chemical means that do not involve life, providing a powerful challenge to vitalism. [93], The development and popularization of the polymerase chain reaction (PCR) in mid-1980s (by Kary Mullis and others at Cetus Corp.) marked another watershed in the history of modern biotechnology, greatly increasing the ease and speed of genetic analysis. [47], Wallace, following on earlier work by de Candolle, Humboldt and Darwin, made major contributions to zoogeography. This enabled worldwide access to better measurements, theoretical models, complex simulations, theory predictive model experimentation, analysis, worldwide internet observational data reporting, open peer-review, collaboration, and internet publication. Biology ‘Ideas, Innovation, Invention’ theme of 2nd IdeaFestival Bowling Green. Carl Linnaeus published a basic taxonomy for the natural world in 1735 (variations of which have been in use ever since), and in the 1750s introduced scientific names for all his species. Van Leeuwenhoek was the first person to see bacteria, which he described as little animals that moved about here, there, and everywhere. Although this discovery is very recent, we’re sure that we’ll be hearing lots more about CRISPR in the future. The Taoist tradition of Chinese alchemy, for example, can be considered part of the life sciences due to its emphasis on health (with the ultimate goal being the elixir of life). [24] Claudius Galen became the most important authority on medicine and anatomy. Improved laboratory techniques such as chromatography and electrophoresis led to rapid advances in physiological chemistry, whichâas biochemistryâbegan to achieve independence from its medical origins. [42] Fossils discovered and described by Gideon Mantell, William Buckland, Mary Anning, and Richard Owen among others helped establish that there had been an 'age of reptiles' that had preceded even the prehistoric mammals. Since that fateful day, the genes for other diseases, such as Huntington’s disease, inherited forms of breast cancer, sickle cell anemia, Down syndrome, Tay-Sachs disease, hemophilia, and muscular dystrophy, have been found. Beginning with the lab of Paul Berg in 1972 (aided by EcoRI from Herbert Boyer's lab, building on work with ligase by Arthur Kornberg's lab), molecular biologists put these pieces together to produce the first transgenic organisms. [64], Hugo de Vries tried to link the new genetics with evolution; building on his work with heredity and hybridization, he proposed a theory of mutationism, which was widely accepted in the early 20th century. [86], Biotechnology in the modern sense of genetic engineering began in the 1970s, with the invention of recombinant DNA techniques. The tremendous success of experimental approaches to development, heredity, and metabolism in the 1900s and 1910s demonstrated the power of experimentation in biology. The word biology is formed by combining the Greek Î²Î¯Î¿Ï (bios), meaning "life", and so the suffix '-logy', meaning "science of", "knowledge of", "study of", "about of", based on the Greek verb λÎγειν, 'legein' "to select", "to gather" (cf. To mill means to grind, and that invariably means to grind grain. The smallpox vaccine was so effective that doctors were able to totally eradicate this disease from the human population. Most inventions are simple to build yet impressive enough to … In the meantime, a variety of theories of inheritance (based on pangenesis, orthogenesis, or other mechanisms) were debated and investigated vigorously. This ancient work was further developed in the Middle Ages by Muslim physicians and scholars such as Avicenna. The scientific study of heredity grew rapidly in the wake of Darwin's Origin of Species with the work of Francis Galton and the biometricians. Most information about the training and domestication of animals was probably transmitted orally, but one text dealing with the training of horses has survived. )[85], Biotechnology in the general sense has been an important part of biology since the late 19th century. By the 1880s, bacteriology was becoming a coherent discipline, especially through the work of Robert Koch, who introduced methods for growing pure cultures on agar gels containing specific nutrients in Petri dishes. Plant Growth and Development: Sending Signals with Plant Hormones, How Living Things Obtain Matter and Energy for Growth. Soon after, others began using plasmid vectors and adding genes for antibiotic resistance, greatly increasing the reach of the recombinant techniques. See more ideas about inventions, cool inventions, invention convention. Dioscorides wrote a pioneering and encyclopaedic pharmacopoeia, De Materia Medica, incorporating descriptions of some 600 plants and their uses in medicine. [87] Restriction enzymes were discovered and characterized in the late 1960s, following on the heels of the isolation, then duplication, then synthesis of viral genes. [9][10][11] When a person became ill, doctors prescribed both magical formulas to be recited and medicinal treatments. [67] In 1980 Luis Alvarez and Walter Alvarez proposed the hypothesis that an impact event was responsible for the CretaceousâPaleogene extinction event. [58], The ecological succession concept, pioneered in the 1900s and 1910s by Henry Chandler Cowles and Frederic Clements, was important in early plant ecology. Part 1: 5 invention/ideas from the Scientific Revolution-Concave Lens (1451): It was used to magnify images. (And now, using the same strategy, we’re very close to eradicating polio!). Many of Theophrastus' names survive into modern times, such as carpos for fruit, and pericarpion for seed vessel. [90] Researchers learned to control the expression of transgenes, and were soon racingâin both academic and industrial contextsâto create organisms capable of expressing human genes for the production of human hormones. November 30, 2020. By the end of the 19th century the concept of enzymes was well established, though equations of chemical kinetics would not be applied to enzymatic reactions until the early 20th century. Prominent in this movement were Vesalius and Harvey, who used experimentation and careful observation in physiology, and naturalists such as Linnaeus and Buffon who began to classify the diversity of life and the fossil record, as well as the development and behavior of organisms. Some of the most popular appliances of all time are those made for the household. Félix d'Herelle's isolation of bacteriophage during World War I initiated a long line of research focused on phage viruses and the bacteria they infect.

He made countless observations of nature, especially the habits and attributes of plants and animals in the world around him, which he devoted considerable attention to categorizing. [89], Following Asilomar, new genetic engineering techniques and applications developed rapidly. Lamarckism, or the theory of inheritance of acquired characteristics also had many adherents. In population ecology, debate over group selection was brief but vigorous; by 1970, most biologists agreed that natural selection was rarely effective above the level of individual organisms. Between 1910 and 1915, Thomas Hunt Morgan and the "Drosophilists" in his fly lab forged these two ideasâboth controversialâinto the "Mendelian-chromosome theory" of heredity. This may have included knowledge of human and animal anatomy and aspects of animal behavior (such as migration patterns). Weismannism was extremely influential, especially in the new field of experimental embryology. The main point of Darwin’s theory is that organisms with traits that are better suited to the conditions in which they live are more likely to survive and reproduce, passing on their traits to future generations. [9][10][11] The profession was passed down from father to son and was held in high regard.
