History of genetics established the concept of dominance, recognizing that when some plant varieties are crossed, certain characteristics (present in one parent) usually appear in the offspring; he also found that some ancestral characteristics found in neither parent may appear in offspring. However, plant breeders made little attempt to establish a theoretical foundation for their work or to share their knowledge with current work of physiology, although Gartons Agricultural Plant Breeders in England explained their system. In breeding experiments between 1856 and 1865, Gregor Mendel first traced inheritance patterns of certain traits in pea plants and showed that they obeyed simple statistical rules
History of Western civilization founded. Many Westerners became less religious in this period, although a majority of people still held traditional Christian beliefs. The 1859 publication of "On the Origin of Species", by the English naturalist Charles Darwin, provided an alternative hypothesis for the development, diversification, and design of human life to the traditional poetic scriptural explanation known as Creationism. According to Darwin, only the organisms most able to adapt to their environment survived while others became extinct. Adaptations resulted in changes in certain populations of organisms which could eventually cause the creation of new species. Modern genetics started with Gregor Johann Mendel, a
