Abstract
in English, Portuguese

In 1868, Darwin published his book The variation of animals and plants under domestication, which laid out his theory of heredity. This included the assumption that development was essential to understanding the evolutionary process. This present article reassesses the Darwinian theory of pangenesis in order to revisit its historical value. The conclusion is that the theory of pangenesis was well-suited to its time, and additionally, reflections of this assumption can be found in work in new areas known as evolutionary biology of development (evo-devo) and epigenetics.

Resumo Em 1868, Darwin publica seu livro The variation of animals and plants under domestication, no qual expõe sua teoria da hereditariedade. Nela se encontrava o pressuposto de que o desenvolvimento era fundamental para compreensão do processo evolutivo. No presente trabalho, é feita uma releitura da teoria darwiniana da pangênese, no intuito de rediscutir seu valor histórico. Conclui-se que a teoria da pangênese estava bem adequada a seu tempo e, mais do que isso, é possível encontrar ressonâncias de seu pressuposto em trabalhos das novas áreas biologia evolutiva do desenvolvimento (evo-devo) e epigenética.
