Aristotle:  (384-322 BC)  Greek philosopher, a student of Plato and teacher of Alexander the Great.   He was one of the earlier taxonomists.  He classified living things into two groups: Plants and Animals.  He grouped plants into herbs, shrubs and trees.  He grouped animals into  those that live on land, in the air and in the water.  He listed about 500 species of organisms.
Galileo Galilei:  (1564 – 1642 )  Italian scientist.   His achievements include improvements to the telescope and consequent astronomical observations, and support for Copernicanism.  Galileo has been called the "father of  astronomy”,  "father of modern physics”, "father of science”  and  “father of modern science”.  Perhaps more than any other single person, was responsible for the birth of modern science.Charles Darwin:  (1809 – 1882) 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”.
Alfred RusselWallace:  ( 1823 – 1913)  British naturalist, explorer, geographer, anthropologist and biologist. He is best known for independently proposing a theory of evolution due to natural selection that prompted Charles Darwin to publish his own theory.
Anton van Leeuwenhoek:   (1632-1723)  Dutch lensmaker.  He made many improvements in microscopes. Considered the “father of microscopy”.  He was the first to seeand describe bacteria (1674), yeast plants, the teeming life in a drop of water, and the circulation of blood corpuscles in capillaries. His microscopes were simple microscopes, consisting of only one magnifying lens.  Even so, they were the best of their time.
Robert Hooke:  (1635-1703)  English scientist.  He used a microscope to examine very thin slices of cork.  He observed that the cork wasnot solid. Instead, it was composed of tiny, hollow boxes that he called cells.  Hookes’s publication of his drawings and descriptions led other scientists of that time to look for evidence of cells.
Gregor Mendel:  (182-1884) was an Austrian Agustinian priest and scientist, who gained posthumous fame as the figurehead of the new science of genetics or his study of the inheritance of certain traitsin 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.
Alexander Oparin:    (1894 - 1980) Soviet biochemist.  Notable for his contributionsto the theory of the origin of life and for his authorship of the book The Origin of Life.  He proposed that life began in the early oceans that contained simple compounds.  He suggested that energy from ultraviolet radiation and lightning could produce chemical reactions in the air. Such reactions would form simple organic compounds such as amino acids and nitrogen bases.    Rain would carrythese molecules into the oceans where a kind of “primordial soup”, a mixture containing all the ingredients necessary for life, would form.   He also developed the foundations for industrial biochemistry in the USSR.
Harold Urey  (1893-1981)  and Stanley Miller :  (1930 - 2007)  were American chemists and biologists. In Chicago,  Miller was a student of Harold Urey.  They tested Oparin’s hypothesisof chemical evolution. They placed a mixture of gases into a flask containing water-  These gases were present in the proportions believed present in the primitive atmosphere of Earth.  The flask was subjected to electrical sparks that simulated lightning.  They repeatedly heated and cooled the mixture, simulating changes in daily temperature. After a week of such treatment, they analyzed the...
