The Scientist from a Flourishing Sex-Life to Modern DNA Technology
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. -
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. -
Alfred Russel Wallace and the Darwinian Species Concept
Gayana 73(2): Suplemento, 2009 ISSN 0717-652X ALFRED RUSSEL WALLACE AND THE Darwinian SPECIES CONCEPT: HIS paper ON THE swallowtail BUTTERFLIES (PAPILIONIDAE) OF 1865 ALFRED RUSSEL WALLACE Y EL concepto darwiniano DE ESPECIE: SU TRABAJO DE 1865 SOBRE MARIPOSAS papilio (PAPILIONIDAE) Jam ES MA LLET 1 Galton Laboratory, Department of Biology, University College London, 4 Stephenson Way, London UK, NW1 2HE E-mail: [email protected] Abstract Soon after his return from the Malay Archipelago, Alfred Russel Wallace published one of his most significant papers. The paper used butterflies of the family Papilionidae as a model system for testing evolutionary hypotheses, and included a revision of the Papilionidae of the region, as well as the description of some 20 new species. Wallace argued that the Papilionidae were the most advanced butterflies, against some of his colleagues such as Bates and Trimen who had claimed that the Nymphalidae were more advanced because of their possession of vestigial forelegs. In a very important section, Wallace laid out what is perhaps the clearest Darwinist definition of the differences between species, geographic subspecies, and local ‘varieties.’ He also discussed the relationship of these taxonomic categories to what is now termed ‘reproductive isolation.’ While accepting reproductive isolation as a cause of species, he rejected it as a definition. Instead, species were recognized as forms that overlap spatially and lack intermediates. However, this morphological distinctness argument breaks down for discrete polymorphisms, and Wallace clearly emphasised the conspecificity of non-mimetic males and female Batesian mimetic morphs in Papilio polytes, and also in P. -
Instr Uct Or's Guide Science
Scientists Of The Past SCIENCE Lesson Objectives • Students will compare and contrast how the rules of society restricted the progress of science in the past. • Students will list several famous scientists from history. Activities Checklist In this lesson, the student will • Watch the instructional video about how the rules of society restricted the progress of science in the past and the scientists who, over time, were able to break away from these restrictions • Interact with My Book and learn about how the rules of society restricted the progress of science in the past • Complete the crossword puzzle, in the Science Activities Workbook, by determining the scientist who made each cited discovery • Complete all learning activities assessing understanding of the sequence of scientifi c events and discoveries Video Summary Students are given a modern-day scenario of reading something aloud in front of the classroom to better understand the stress scientists felt during the sixteenth and seventeenth centuries, when they were presenting new scientifi c theories to society. Scientists of the past were not always respected. Sometimes publicly voicing their scientifi c opinions could result in jail, exile, or even death. Religion determined what could or could not be accepted as explanations and discoveries. When a scientist would come up with a new explanation for why something occurred in nature, he or she would often have to argue the claim against the church -- and the church always won. After many, many years, the scientifi c community was able to break away from the church, resulting in numerous scientifi c endeavors. Some of the most famous scientists include Anton van Leeuwenhoek (improved the microscope), Carl Linnaeus (developed the classifi cation of life on Earth), Charles Darwin (developed the Theory of Evolution by Natural Selection), and Albert Einstein (worked within mathematics, GUIDE INSTRUCTOR’S physics, and astronomy). -

Natural Selection: Charles Darwin & Alfred Russel Wallace
Search | Glossary | Home << previous | next > > Natural Selection: Charles Darwin & Alfred Russel Wallace The genius of Darwin (left), the way in which he suddenly turned all of biology upside down in 1859 with the publication of the Origin of Species , can sometimes give the misleading impression that the theory of evolution sprang from his forehead fully formed without any precedent in scientific history. But as earlier chapters in this history have shown, the raw material for Darwin's theory had been known for decades. Geologists and paleontologists had made a compelling case that life had been on Earth for a long time, that it had changed over that time, and that many species had become extinct. At the same time, embryologists and other naturalists studying living animals in the early 1800s had discovered, sometimes unwittingly, much of the A visit to the Galapagos Islands in 1835 helped Darwin best evidence for Darwin's formulate his ideas on natural selection. He found theory. several species of finch adapted to different environmental niches. The finches also differed in beak shape, food source, and how food was captured. Pre-Darwinian ideas about evolution It was Darwin's genius both to show how all this evidence favored the evolution of species from a common ancestor and to offer a plausible mechanism by which life might evolve. Lamarck and others had promoted evolutionary theories, but in order to explain just how life changed, they depended on speculation. Typically, they claimed that evolution was guided by some long-term trend. Lamarck, for example, thought that life strove over time to rise from simple single-celled forms to complex ones. -
Names of Botanical Genera Inspired by Mythology
Names of botanical genera inspired by mythology Iliana Ilieva * University of Forestry, Sofia, Bulgaria. GSC Biological and Pharmaceutical Sciences, 2021, 14(03), 008–018 Publication history: Received on 16 January 2021; revised on 15 February 2021; accepted on 17 February 2021 Article DOI: https://doi.org/10.30574/gscbps.2021.14.3.0050 Abstract The present article is a part of the project "Linguistic structure of binomial botanical denominations". It explores the denominations of botanical genera that originate from the names of different mythological characters – deities, heroes as well as some gods’ attributes. The examined names are picked based on “Conspectus of the Bulgarian vascular flora”, Sofia, 2012. The names of the plants are arranged in alphabetical order. Beside each Latin name is indicated its English common name and the family that the particular genus belongs to. The article examines the etymology of each name, adding a short account of the myth based on which the name itself is created. An index of ancient authors at the end of the article includes the writers whose works have been used to clarify the etymology of botanical genera names. Keywords: Botanical genera names; Etymology; Mythology 1. Introduction The present research is a part of the larger project "Linguistic structure of binomial botanical denominations", based on “Conspectus of the Bulgarian vascular flora”, Sofia, 2012 [1]. The article deals with the botanical genera appellations that originate from the names of different mythological figures – deities, heroes as well as some gods’ attributes. According to ICBN (International Code of Botanical Nomenclature), "The name of a genus is a noun in the nominative singular, or a word treated as such, and is written with an initial capital letter (see Art. -

History of Taxonomy
History of Taxonomy The history of taxonomy dates back to the origin of human language. Western scientific taxonomy started in Greek some hundred years BC and are here divided into prelinnaean and postlinnaean. The most important works are cited and the progress of taxonomy (with the focus on botanical taxonomy) are described up to the era of the Swedish botanist Carl Linnaeus, who founded modern taxonomy. The development after Linnaeus is characterized by a taxonomy that increasingly have come to reflect the paradigm of evolution. The used characters have extended from morphological to molecular. Nomenclatural rules have developed strongly during the 19th and 20th century, and during the last decade traditional nomenclature has been challenged by advocates of the Phylocode. Mariette Manktelow Dept of Systematic Biology Evolutionary Biology Centre Uppsala University Norbyv. 18D SE-752 36 Uppsala E-mail: [email protected] 1. Pre-Linnaean taxonomy 1.1. Earliest taxonomy Taxonomy is as old as the language skill of mankind. It has always been essential to know the names of edible as well as poisonous plants in order to communicate acquired experiences to other members of the family and the tribe. Since my profession is that of a systematic botanist, I will focus my lecture on botanical taxonomy. A taxonomist should be aware of that apart from scientific taxonomy there is and has always been folk taxonomy, which is of great importance in, for example, ethnobiological studies. When we speak about ancient taxonomy we usually mean the history in the Western world, starting with Romans and Greek. However, the earliest traces are not from the West, but from the East.
