About this listen
At an early stage of development human embryos have gill-like features. Observations like this prompted scientists to suggest that embryo development copies the evolutionary development of the species. Their theory became known as recapitulation theory and had the slogan “ontogeny recapitulates phylogeny”. Many scientists, such as Charles Darwin, disagreed with recapitulation theory even though they agreed that embryos of different species share a lot of similarities. Ultimately as the development of embryos in the womb was better understood recapitulation theory was superseded. Still it left its mark on science, even influencing cognitive research and music theory. Develop your understanding of embryology and listen to this week’s episode of Good in Theory!
