A Brief History of Biology History of Biology Charak, sometimes spelled Caraka, born c. 300 BC was one of the principal contributors to the ancient art and science of Ayurveda, a system of medicine and lifestyle developed in Ancient India. He is sometimes referred to as the Father of Anatomy Aristotle (384 BC – 322 BC) was a Greek philosopher, a student of Plato and teacher of Alexander the Great. Father of Biology Natural philosopher, identified some of the known living characteristics such as reproduction. Hippocrates (460 BC – 370 BC) He is referred to as the Western father of medicine Galen (AD 129 – 217) was a prominent physician, surgeon and philosopher. Galen contributed greatly to the understanding of numerous scientific disciplines including anatomy,physiology, pathology, pharmacology, neurology, philosophy, and logic. - Studied the functions of the kidneys and spinal cord using the Barbary ape. Andreas Vesalius (1514 –1564) was an anatomist, physician, and author of one of the most influential books on human anatomy, De humani corporis fabrica (On the Workings of the Human Body). Vesalius was born in Brussels. Vesalius is the Latinized form of Andreas van Wesel. He is sometimes also referred to as Andreas Vesal and Andre Vesale. - was the founder of modern anatomy. - Broke traditions by performing his own dissection using cadavers. William Harvey (1578 – 1657) was an English physician who was the first to describe correctly and in detail the systemic circulation and properties of blood being pumped to the body and lungs by the heart. - Correctly described how the blood is pumped around the body by the heart Marie François Xavier Bichat (1771 –1802), French anatomist and physiologist, was born at Thoirette (Jura). Bichat is best remembered as the father of modern histology and pathology. Despite the fact that he worked without a microscope he was able to advance greatly the understanding of the human body. He was the first to introduce the notion of tissue (tissues) as distinct entities. He maintained that diseases attacked tissues rather than whole organs. René Joachim Henri Dutrochet (1776 –1847) was a French physician, botanist and physiologist. He investigated and described osmosis, respiration, embryology, and the effect of light on plants. He has been given credit for discovering cell biology and cells in plants and the actual discovery of the process of osmosis. - Was credited for the formation of cell biology - Discovered cells in plants and actual process of osmosis Robert Hooke (1635 – 1703) was an English natural philosopher, architect and polymath who played an important role in the scientific revolution, through both experimental and theoretical work. Hooke is known for his law of elasticity (Hooke's law), his book, Micrographia, and for first applying the word "cell" to describe the basic unit of life. - Coined the term ―Cell‖ - First to observe a plant cell (cork cell) Antonie Philips van Leeuwenhoek (1632 - 1723 ) was a Dutch tradesman and scientist from Delft, Netherlands. He is commonly known as "the Father of Microbiology", and considered to be the first microbiologist. He is best known for his work on the improvement of the microscope and for his contributions towards the establishment of microbiology. Using his handcrafted microscopes he was the first to observe and describe single celled organisms, which he originally referred to as animalcules, and which we now refer to as microorganisms. He was also the first to record microscopic observations of muscle fibers, bacteria, spermatozoa and blood flow in capillaries (small blood vessels). - Helped in the improvement of the microscope - First to describe muscles, blood flow in capillaries, spermatozoa, bacteria and protozoans Carl Linnaeus (Latinized as Carolus Linnaeus (1707 –1778) was a Swedish botanist, physician, and zoologist, who laid the foundations for the modern scheme of binomial nomenclature. He is known as the father of modern taxonomy, and is also considered one of the fathers of modern ecology. - Laid the foundations for the modern scheme of Taxonomy - Introduced the use of binomial nomenclature (genus + species) Francesco Redi (1626 –1697) was an Italian physician, naturalist, and poet. He is most well-known for his series of experiments, published in 1668 as Esperienze Intorno alla Generazione degl'Insetti (Experiments on the Generation of Insects) which is regarded as one of the first steps in refuting "spontaneous generation" - a theory also known as Aristotelian abiogenesis. Gregor Johann Mendel (1822–1884) was an Augustinian priest and scientist, who gained posthumous fame as the figurehead of the new science of genetics for his study of the inheritance of certain traits in pea plants. Mendel showed that the inheritance of these traits follows particular laws, which were later named after him. The significance of Mendel's work was not recognized until the turn of the 20th century. The independent rediscovery of these laws formed the foundation of the modern science of genetics. - Father of Genetics - First to discover the ability of organisms (pea plants) to pass traits from parents to offspring. Thomas Robert Malthus FRS (1766 –1834), was a British scholar, influential in political economy and demography . Malthus has become widely known for his theories concerning population and its increase or decrease in response to various factors. Louis Pasteur (1822 –1895) was a French chemist and microbiologist born in Dole. He is remembered for his remarkable breakthroughs in the causes and preventions of disease. His discoveries reduced mortality from puerperal fever, and he created the first vaccine for rabies. His experiments supported the germ theory of disease He was best known to the general public for inventing a method to stop milk and wine from causing sickness, a process that came to be called pasteurization. He is regarded as one of the three main founders of microbiology, together with Ferdinand Cohn and Robert Koch. - Confirmed the theory of diseases - Introduced the process of pasteurization - First to create a vaccine against rabies - Disproved the theory of spontaneous generation Sir Alexander Fleming (1881 –1955) was a Scottish biologist and pharmacologist. Fleming published many articles on bacteriology, immunology and chemotherapy. His best-known achievements are the discovery of the enzyme lysozyme in 1923 and the antibiotic substance penicillin from the fungus Penicillium notatum in 1928, for which he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Walter Florey and Ernst Boris Chain. - Isolated and discover the antibiotic properties of penicillin. Charles Robert Darwin (1809 –1882) was an English naturalist who established that all species of life have descended over time from common ancestors, and proposed the scientific theory that this branching pattern of evolution resulted from a process that he called natural selection. He published his theory with compelling evidence for evolution in his 1859 book On the Origin of Species. In modified form, Darwin's scientific discovery is the unifying theory of the life sciences, explaining the diversity of life - Pioneered the evolutionary theory - Proponent of the theory of natural selection Watson and Crick were James D. Watson and Francis Crick who, using x-ray diffraction data proposed the double helix or spiral staircase structure of the DNA molecule in 1953. Their article, Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid, is celebrated for its treatment of the B form of DNA (B- DNA), and as the source of Watson-Crick base pairing of nucleotides. They were, with Maurice Wilkins, awarded the Nobel Prize in Physiology or Medicine in 1962. - Discovered the double helix structure of the DNA Jean-Baptiste de la Marck (1744–1829), often just known as "Lamarck", was a French soldier, naturalist, academic and an early proponent of the idea that evolution occurred and proceeded in accordance with natural laws. n the modern era, Lamarck is primarily remembered for a theory of inheritance of acquired characteristics, called soft inheritance or Lamarckism. In 1801, he published Système des animaux sans vertèbres, a major work on the classification of invertebrates, a term he invented. In an 1802 publication, he became one of the first to use the term biology in its modern sense. Lamarck continued his work as a premier authority on invertebrate zoology. He is remembered, at least in malacology, as a taxonomist of considerable stature Theodor Schwann (1810–1882) was a German physiologist. His many contributions to biology include the development of cell theory, the discovery of Schwann cells in the peripheral nervous system, the discovery and study of pepsin, the discovery of the organic nature of yeast, and the invention of the term metabolism. Matthias Jakob Schleiden (1804 - 1881) was a German botanist and co-founder of the cell theory, along with Theodor Schwann and Rudolf Virchow. He also recognized the importance of the cell nucleus, discovered in 1831 by the Scottish botanist Robert Brown, and sensed its connection with cell division. Robert Brown (1773 –1858) was a Scottish botanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include the discovery of the cell nucleus and cytoplasmic streaming; the first observation of Brownian motion; Hugo Marie de Vries (1848–1935) was a Dutch botanist and one of the first geneticists. He is known chiefly for suggesting the concept of genes,

    The Scientist From a Flourishing Sex-life to Modern DNA Technology Linnaeus the Scientist ll of a sudden you are standing there, in the bo- tanic garden that is to be Linnaeus’s base for a whole lifetime of scientific achievements. It is a beautiful spring day in Uppsala, the sun’s rays warm your heart as cheerfully as in your own 21st century. The hus- tle and bustle of the town around you break into the cen- trally located garden. Carriage wheels rattle over the cob- blestones, horses neigh, hens cackle from the house yards. The acrid smell of manure and privies bears witness to a town atmosphere very different from your own. You cast a glance at what is growing in the garden. The beds do not look particularly well kept. In fact, the whole garden gives a somewhat dilapidated impression. Suddenly, in the distance, you see a young man squat- A ting down by one of the beds. He is looking with great concentration at a small flower, examining it closely through a magnifying glass. When he lifts his head for a moment and ponders, you recognise him at once. It is Carl von Linné, or Carl Linnaeus as he was originally called. He looks very young, just over 20 years old. His pale cheeks tell you that it has been a harsh winter. His first year as a university student at Uppsala has been marked by a lack of money for both food and clothes as well as for wood to warm his rented room. 26 linnaean lessons • www.bioresurs.uu.se © 2007 Swedish Centre for School Biology and Biotechnology, Uppsala University, Sweden.

  • Insight from the Sociology of Science
    CHAPTER 7 INSIGHT FROM THE SOCIOLOGY OF SCIENCE Science is What Scientists Do It has been argued a number of times in previous chapters that empirical adequacy is insufficient, in itself, to establish the validity of a theory: consistency with the observable ‘facts’ does not mean that a theory is true,1 only that it might be true, along with other theories that may also correspond with the observational data. Moreover, empirical inadequacy (theories unable to account for all the ‘facts’ in their domain) is frequently ignored by individual scientists in their fight to establish a new theory or retain an existing one. It has also been argued that because experi- ments are conceived and conducted within a particular theoretical, procedural and instrumental framework, they cannot furnish the theory-free data needed to make empirically-based judgements about the superiority of one theory over another. What counts as relevant evidence is, in part, determined by the theoretical framework the evidence is intended to test. It follows that the rationality of science is rather different from the account we usually provide for students in school. Experiment and observation are not as decisive as we claim. Additional factors that may play a part in theory acceptance include the following: intuition, aesthetic considerations, similarity and consistency among theories, intellectual fashion, social and economic influences, status of the proposer(s), personal motives and opportunism. Although the evidence may be inconclusive, scientists’ intuitive feelings about the plausibility or aptness of particular ideas will make it appear convincing. The history of science includes many accounts of scientists ‘sticking to their guns’ concerning a well-loved theory in the teeth of evidence to the contrary, and some- times in the absence of any evidence at all.

  • The Joys and Burdens of Our Heroes 12/05/2021
    More Fun Than Fun: The Joys and Burdens of Our Heroes 12/05/2021 An iconic photo of Konrad Lorenz with his favourite geese. Photo: Willamette Biology, CC BY-SA 2.0 This article is part of the ‘More Fun Than Fun‘ column by Prof Raghavendra Gadagkar. He will explore interesting research papers or books and, while placing them in context, make them accessible to a wide readership. RAGHAVENDRA GADAGKAR Among the books I read as a teenager, two completely changed my life. One was The Double Helix by Nobel laureate James D. Watson. This book was inspiring at many levels and instantly got me addicted to molecular biology. The other was King Solomon’s Ring by Konrad Lorenz, soon to be a Nobel laureate. The study of animal behaviour so charmingly and unforgettably described by Lorenz kindled in me an eternal love for the subject. The circumstances in which I read these two books are etched in my mind and may have partly contributed to my enthusiasm for them and their subjects. The Double Helix was first published in London in 1968 when I was a pre-university student (equivalent to 11th grade) at St Joseph’s college in Bangalore and was planning to apply for the prestigious National Science Talent Search Scholarship. By then, I had heard of the discovery of the double-helical structure of DNA and its profound implications. I was also tickled that this momentous discovery was made in 1953, the year of my birth. I saw the announcement of Watson’s book on the notice board in the British Council Library, one of my frequent haunts.

  • Of Dahlia Myths.Pub
    Cavanilles’ detailed illustrations established the dahlia in the botanical taxonomy In 1796, the third volume of “Icones” introduced two more dahlia species, named D. coccinea and D. rosea. They also were initially thought to be sunflowers and had been brought to Spain as part of the Alejandro Malaspina/Luis Neé expedition. More than 600 drawings brought the plant collection to light. Cavanilles, whose extensive correspondence included many of Europe’s leading botanists, began to develop a following far greater than his title of “sacerdote” (priest, in French Abbé) ever would have offered. The A. J. Cavanilles archives of the present‐day Royal Botanical Garden hold the botanist’s sizable oeu‐ vre, along with moren tha 1,300 letters, many dissertations, studies, and drawings. In time, Cavanilles achieved another goal: in 1801, he was finally appointed professor and director of the garden. Regrettably, he died in Madrid on May 10, 1804. The Cavanillesia, a tree from Central America, was later named for this famousMaterial Spanish scientist. ANDERS DAHL The lives of Dahl and his Spanish ‘godfather’ could not have been any more different. Born March 17,1751, in Varnhem town (Västergötland), this Swedish botanist struggled with health and financial hardship throughout his short life. While attending school in Skara, he and several teenage friends with scientific bent founded the “Swedish Topographic Society of Skara” and sought to catalogue the natural world of their community. With his preacher father’s support, the young Dahl enrolled on April 3, 1770, at Uppsala University in medicine, and he soon became one of Carl Linnaeus’ students.

  • Introduction the Age of Biology
    INTRODUCTION THE AGE OF BIOLOGY An organism is the product of its genetic constitution and its en- vironment . no matter how uniform plants are genotypically, they cannot be phenotypically uniform or reproducible, unless they have developed under strictly uniform conditions. — Frits Went, 1957 A LITERARY and cinematic sensation, Andy Weir’s The Martian is engi- neering erotica. The novel thrills with minute technical details of com- munications, rocket fuel, transplanetary orbital calculations, and botany. The action concerns a lone astronaut left on Mars struggling to survive for 1,425 days using only the materials that equipped a 6-person, 30-day mission. Food is an early crisis: the astronaut has only 400 days of meals plus 12 whole potatoes. Combining his expertise in botany and engineer- ing, the astronaut first works to create in his Mars habitat the perfect Earth conditions for his particular potatoes, namely, a temperature of 25.5°C, plenty of light, and 250 liters of water. Consequently, his potatoes grow at a predicted rate to maturity in 40 days, thus successfully conjur- ing sufficient food to last until his ultimate rescue at the end of the novel. Unlike so many of the technical details deployed throughout the novel, the ideal conditions for growing potatoes are just a factoid. Whereas readers of the novel get to discover how to make water in a process oc- cupying twenty pages, the discovery of the ideal growing conditions of the particular potatoes brought to Mars is given one line.1 Undoubtedly, making water from rocket fuel is tough, but getting a potato’s maximum 3 © 2017 University of Pittsburgh Press.

  • De Plantis, Once Belonging to Maimonides’.[3]
    Fragment of the Month: January 2017 Plants on Maimonides’ bookshelf: T-S Ar.41.41 by Gabriele Ferrario Which were the favourite books of Moses Maimonides? Which titles would have found space on his bookshelf? Maimonides’ letter to the Hebrew translator of most of his Judaeo-Arabic production, Samuel ibn Tibbon, contains revealing passages regarding the books that Maimonides considered the basis of any solid philosophical education.[1] No wonder the place of honour is occupied by the works of Aristotle, which became available to the Arabic-speaking world thanks to the spectacular effort of Arabisation of Greek sciences conducted under the Abbasid caliphs. Maimonides describes Aristotelian treatises as ‘the roots and foundations of all works on the sciences’. But Aristotle’s philosophy was not always easy to understand for a medieval reader, and Maimonides recognised the utility of later commentaries and systematisations of Aristotelian works produced by philosophers of Late Antiquity and Islam, in particular the works by Alexander of Aphrodisias (2nd–3rd c.), Themistius (d. 390 CE), and Averroes (d. 1198). As much as praising his favourite authors, Maimonides is very keen on downplaying the importance of authors he fancied less, and writes to Ibn Tibbon that reading commentaries by Abū Yaḥyā ibn al-Biṭrīq (9th century), Yaḥyā ibn ʿAdī (10th c.) and by Abū al-Faraj ibn al-Tayyib (11th c.) would be a waste of time. A similarly dismissive approach characterises Maimonides’ stance towards Plato and other Greek classical philosophers: Aristotle said it all, why should one look for anything else? Among Muslim philosophers, Maimonides praises Al-Fārābī (10th c.), particularly for his logical works, Ibn Bajja (the Latin Avempace, 11th–12th c.) and Averroes (12th c.) for his numerous Aristotelian commentaries; he also remarks that books by Avicenna (11th c.) are worth studying, even if they are not as good as Al- Fārābī’s.

  • Interpreting the History of Evolutionary Biology Through a Kuhnian Prism: Sense Or Nonsense?
    Interpreting the History of Evolutionary Biology through a Kuhnian Prism: Sense or Nonsense? Koen B. Tanghe Department of Philosophy and Moral Sciences, Universiteit Gent, Belgium Lieven Pauwels Department of Criminology, Criminal Law and Social Law, Universiteit Gent, Belgium Alexis De Tiège Department of Philosophy and Moral Sciences, Universiteit Gent, Belgium Johan Braeckman Department of Philosophy and Moral Sciences, Universiteit Gent, Belgium Traditionally, Thomas S. Kuhn’s The Structure of Scientific Revolutions (1962) is largely identified with his analysis of the structure of scientific revo- lutions. Here, we contribute to a minority tradition in the Kuhn literature by interpreting the history of evolutionary biology through the prism of the entire historical developmental model of sciences that he elaborates in The Structure. This research not only reveals a certain match between this model and the history of evolutionary biology but, more importantly, also sheds new light on several episodes in that history, and particularly on the publication of Charles Darwin’s On the Origin of Species (1859), the construction of the modern evolutionary synthesis, the chronic discontent with it, and the latest expression of that discon- tent, called the extended evolutionary synthesis. Lastly, we also explain why this kind of analysis hasn’t been done before. We would like to thank two anonymous reviewers for their constructive review, as well as the editor Alex Levine.
