The Correlation between Relatives on the Supposition of Mendelian Inheritance
In 1900, scientists rediscovered Mendelian inheritance. But, there was a debate about how it worked. Some scientists, like Karl Pearson, believed in Charles Darwin's idea. Darwin said small changes in creatures are important for evolution. Others, like William Bateson, believed big changes were more important. Fisher believed small changes could be passed on through genes. He wrote about this in 1911 when he was a student. He showed that this is true in the paper he wrote in 1918.
