Oscar Hertwig

Oscar Hertwig was a German zoologist renowned for his pioneering research in cell biology and evolutionary theory. His work on fertilization and the role of the cell nucleus in heredity significantly advanced the understanding of reproduction mechanisms and genetic information transfer. Hertwig's discoveries, including the recognition of chromosome reduction during meiosis, laid the groundwork for modern cytology and genetics. His influence extended beyond zoology, impacting theoretical debates on evolution in the early 20th century.
