He focused instead on what he called “beanbag genetics,” in which “Evolutionary genetics was essentially presented as an input or output of genes, as the adding of certain beans to a beanbag and the withdrawing of others” (Mayr 1959).

From his many publications on the subject of evolution, it is clear that Mayr had been much troubled by the contribution of geneticists to the understanding of the process of evolution. For instance, in the first chapter of his well known book Animal Species and Evolution (1963), he wrote:

The assumption made by some geneticists, that it was quite impossible
to have sensible ideas on evolution until the laws of inheritance had
been worked out, is contradicted by the facts. Everyone admits that
