    • The Development of the Neural Crest and the Migration of Neural Crest Cells (NCCs) in the Embryos of Various Vertebrates 

      Hall, Brian K.; Barnes, M. Elizabeth (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2014-08-21)
      This diagram shows how NCCs migrate differently in rats, birds and amphibians. The arrows represent both chronology of NCCs migration and the differential paths that NCCs follow in different classes of animals. The solid ...
    • "Experiments on Artificial Parthenogenesis in Annelids (Chaetopterus) and the Nature of the Process of Fertilization" (1901), by Jacques Loeb 

      Elliott, Steve (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-10)
      Jacques Loeb showed that scientists could achieve artificial parthenogenesis with some types of annelid worm eggs through a series of experiments in 1900. Loeb published the results of his experiments in 1901 as "Experiments ...
    • Friedrich Tiedemann (1781-1861) 

      LaTourelle, Jonathon (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2015-07-07)
      Friedrich Tiedemann studied the anatomy of humans and animals in the nineteenth century in Germany. He published on zoological subjects, on the heart of fish, the anatomy of amphibians and echinoderms, and the lymphatic ...
    • "Further Experiments on Artificial Parthenogenesis and the Nature of the Process of Fertilization" (1900), by Jacques Loeb 

      Elliott, Steve (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-10)
      Jacques Loeb broadened and corrected his earlier claims concerning artificial parthenogenesis in sea urchins in a series of experiments in 1900. He published these findings, "Further Experiments on Artificial Parthenogenesis ...
    • Jacques Loeb (1859-1924) 

      Elliott, Steve (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-08)
      Jacques Loeb experimented on embryos in Europe and the United States at the end of the nineteenth and beginning of the twentieth centuries. Among the first to study embryos through experimentation, Loeb helped found the ...
    • Julius von Sachs (1832-1897) 

      Elliott, Steve (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-10)
      Julius von Sachs helped establish plant physiology through his experiments in latter nineteenth-century Germany. Sachs infused the inchoate discipline of plant physiology with experimental techniques and a mechanistic ...
    • Leonard Hayflick (1928- ) 

      Bartlett, Zane (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2014-07-20)
      Leonard Hayflick studied the processes by which cells age during the twentieth and twenty-first centuries in the United States. In 1961 at the Wistar Institute in the US, Hayflick researched a phenomenon later called the ...
    • The Mechanistic Conception of Life (1912), by Jacques Loeb 

      Elliott, Steve (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-10)
      Jacques Loeb published The Mechanistic Conception of Life in 1912. Loeb's goal for the book was to further disseminate his explanations of organic processes, such as embryonic development and organisms orientations to ...
    • "Mechanistic Science and Metaphysical Romance" (1915), by Jacques Loeb 

      Elliott, Steve (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-10)
      Jacques Loeb published "Mechanistic Science and Metaphysical Romance" in 1915. His goal for the article was to outline his conception of mechanistic science and its relation to other methods of inquiry. Loeb argued that ...
    • "On the Nature of the Process of Fertilization and the Artificial Production of Normal Larvae (Plutei) From the Unfertilized Eggs of the Sea Urchin" (1899), by Jacques Loeb 

      Elliott, Steve (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-10)
      Jacques Loeb developed procedures to make embryos from unfertilized sea urchin eggs in 1899. Loeb called the procedures "artificial parthenogenesis," and he introduced them and his results in "On the Nature of the Process ...
    • The Organism as a Whole: From a Physicochemical Viewpoint (1916), by Jacques Loeb 

      Elliott, Steve (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-10)
      Jacques Loeb published The Organism as a Whole: From a Physicochemical Viewpoint in 1916. Loeb's goal for the book was to refute the claim that physics and chemistry were powerless to completely explain whole organisms ...
