摘要: Thomas Henry Huxley, now often remembered as “Darwin’s bulldog”, wrote an entire book dedicated to crayfish, with no less a goal than showing how the study of crayfish could teach reader all zoology: “how careful one commonest and most insignificant animals, leads us, step by step, from every-day knowledge widest generalizations difficult problems”. In retrospect, Huxley laid out argument for model organisms several decades before another Thomas, namely, Hunt Morgan, started using fruit flies organisms, which became wellspring biological information in twentieth century. While biology nineteenth century emphasised work on diverse species field, was driven few lab, whether they were rats or Arabidopsis thaliana.
