Just as the significance of Malthus' observation had remained unnoticed until the time was ripe, so did Mendel's contribution. Mendel read his paper, "Experiments on Plant Hybridization," in 1865, and published it the following year.īut Mendel's work received little notice and was cited a mere three times over the next 35 years. He discovered the patterns and importance of recombinant recessive and dominant traits. Two years before the Darwin-Wallace paper, an obscure Austrian monk by the name of Gregor Mendel had started work on crossbreeding varieties of peas. ![]() Both Darwin and Wallace acknowledged they did not know the precise mechanism by which the traits of the successful surviving organisms in one generation were passed on to their descendants in the next. ![]() And it is the sesquicentennial of the book next year, along with the bicentennial of Darwin's birth, which will be more widely marked than the 1858 event.īut our story does not end here. That produced an intellectual and cultural splash, perhaps the largest of the 19th century. Wallace was already on to his next big thing: amassing huge collections of natural specimens in hopes of winning both fame and fortune.ĭarwin was on to his next big thing: At the urging of his friends, he published a magnificent one-volume summary of his work, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, in 1859. in every generation the inferior would inevitably be killed off and the superior would remain - that is, the fittest would survive."īut the same differences in temperament that had led to Darwin's delay and Wallace's rush to publication now worked to Darwin's advantage. As Wallace wrote, "It suddenly flashed upon me. Malthus observed that population was held in check because not every individual would survive to reproduce. Wallace had read it around 1846, but first saw its import for explaining evolution while he lay recovering from fever in Malaysia a dozen years later. What is remarkable is that both Darwin and Wallace credited their central insight to reading Thomas Malthus' essay, Population, first published in 1798.ĭarwin read Malthus in 1838 and immediately realized how it applied to his own work. It was more like simultaneous announcement. Was this a remarkable case of simultaneous discovery? Not quite. ![]() But the paper was accepted for publication in the society's Proceedings later that year. The society had routine business to transact. The paper and the meeting did not cause an immediate sensation.
