What is unique about Mendel that makes him the loneliest genius in the history of science, 35 years ahead of the whole era? It's not because Mendel's work is unpopular. On the contrary, when Mendel published the Law of Genetics, the academic circles at that time were in urgent need of it. Nor is it because his work is unknown. Before 1900, his immortal paper on pea hybridization experiment was cited at least ten times, and some of the cited people were authoritative in botany. He also had a long-term correspondence with negri, one of the most famous botanists at that time. But these people don't think Mendel's hybrid research is great, or even disdain it. Why is this? Because he is unfortunately in the shadow of a giant. Darwin's book Origin of Species published in 1859 triggered a revolution in the field of biology, and the study of evolution was the most striking field at that time. People who are engaged in genetic research, even Mendel, feel that they are also solving the problem of biological evolution-he mentioned in his paper 1866 that the purpose of his pea experiment is to "solve a problem whose importance to the history of biological evolution cannot be underestimated." In the view of researchers at that time, interspecific hybridization was much more significant to evolution than intraspecific hybridization. Mendel himself also interbred with kidney beans and chamomile. His work is often mentioned by botanists at 1900, and his pea experiment seems to be just a trivial work, which is not worth mentioning.
