THE MEANING OF BIOLOGY BIOLOGY It comes from Greek word "bios" means life, and "logos" which means to study. It is a body of knowledge that focuses on the study of living things, together with all related occurrences and guiding concepts. It is a natural science since it deals with the study of living things, including their shapes, structures, compositions, traits, functions, and classifications It is the study of organic (living) nature. It is also known as life science The term was coined by Jean Baptiste-Lamarck. The father of biology is Aristotle.

FAMOUS PERSONALITIES IN THE FIELD OF BIOLOGY Thales of Miletus "Father of Natural Philosophy" Natural Philosophy Philosophy of nature (from Latin philosophia naturalis) was the philosophical study of nature and the physical universe that was dominant before the development of modern science. It is considered to be the precursor of natural science. Aristotle "Father of Biology and Zoology" "Father of Ancient Taxonomy" Hippocrates "Father of Medicine" According to him, the human body is made up of 4 humors. The Theory of the Four Humors Hippocrates' theory of the four humors basically states that the human body is made up of four substances. The theory refers to these substances as "humors." For ideal health, they have to be in perfect balance. When this balance is lost, it leads to sickness. a. Black bile; b. Yellow bile; c. Blood d. Phlegm Robert Hooke Hooke's most notable publication was Micrographia in 1665. In his experiments using a cork (Oak Tree), he was able to coin the term "cell". "Father of Cytology" Anton Van Leeuwenhoek "Father of Microscopy" He is the first person to observe protozoa and bacteria and calls "animalcules" - little animals. Them Gregor Mendel "Father of Genetics" He is an Austrian monk. Through his experiments on pea plants (Pisum sativum), he discovered the fundamental laws of inheritance. Theophrastus "Father of Botany/Plant Science" Francesco Redi "Father of Modern Parasitology" He challenged the Spontaneous Generation Theory. Spontaneous Generation Theory - suggested that living things arose from non-living things Herbert Spencer He coined the term, "survival of the fittest". William Harvey He discovered the circulation of the blood. Andreas Vesalius He was the first to perform public dissection on a human corpse, a practice that was unusual in the Middle Ages due to spiritual beliefs. Aelius Galenus or Claudius Galenus (Galen or Galen of Pergamon) He was an ancient Greek physician anatomist, and philosopher. He discovered that arteries carry blood. Carolus Linnaeus (also known as Carl von Linne) "Father of Modern Taxonomy" He is the one who formalized the modem system of naming organisms called binomial nomenclature. Binomial Nomenclature - This formal system of naming organisms consists of two Latinized names, the genus and the species. Genus and species names are always italicized. Ex. Homo sapiens x Jean Baptiste Lamarck He is best known for his Theory of Inheritance of Acquired Characteristics and the Theory of Use and Disuse. Matthias Schleiden He said that all plants are made of cells; a botanist. Theodore Schwann He said that all animals are made of cells; a zoologist. Rudolf Virchow He said that cells came from pre-existing cells. Robert Brown He discovered the nucleus within cells. He is also famous for his discovery of the Brownian movement. Charles Darwin "Father of Evolution" "On the Origin of Species" - The book of Charles Darwin. He made his studies in evolution on Galapagos Island with his ship HMS Beagle. He published the book in December 1859. Natural Selection theory It is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring (differential reproduction). Edward Jenner He is the first person to discover the smallpox vaccine. The word vaccine comes from the word "vacca" which means cow. Robert Koch "Father of Bacteriology". He formulated the Germ Theory of Disease and discovered Bacillus anthracis and Tubercle bacillus. Germ theory of disease - He proposed that microorganisms (germs) can lead to a disease. Louis Pasteur "Father of Microbiology" He discovered the process of pasteurization. Pasteurization - It is a process in which water and other substances are treated with mild heat to eliminate pathogens and other harmful microbes, Alexander Fleming "Father of Antibiotics" He discovered Penicillin His accidental discovery was known as "serendipity" Penicillin is an antibiotic drug (antibacterial). Penicillin is made by a fungus, Penicillium notatum. Hugo de Vries "Father of Mutation" Mutation theory It states that living organisms can develop changes to their genes that greatly alter the organism. These changes are passed down to the next generation, and lead to the development of new species. Rosalind Franklin She discovered the structure of DNA in 1953 using X-ray diffraction. Francis Crick & James Watsons They discovered in 1953 the twisted-ladder structure of DNA. Joseph Lister He introduced the "antiseptic technique", which includes steps and procedures to prevent contamination from pathogens or disease-causing organisms. Claude Ephraim ZoBell "Father of Marine Microbiology". He discovered living organisms in extreme ocean depth and 65 species of bacteria. Wendell Meredith Stanley He is the one who crystallized the "Tobacco Mosaic Virus". Crystallization It is the process of transforming the components of a virus into organized particles to describe their structure and other characteristics using an X-Ray crystallography technique. Wilhelm Johannsen He was a geneticist, botanist, and pharmacist from Denmark. His 1903 "pure line" genetics studies are what made him most famous, along with his use of the phrases gene, phenotype, and genotype. Imre Festetics He coined the term "genetics" Imre Festetics used the study of sheep to develop many of the fundamental ideas that make up the field of genetics.  William Whewell He coined the term "scientist" Let’s Check Your Understanding Summative or Oral Recitation will be administered by the instructor.
