Over the years, scientists have proposed several mechanisms by which new genes are generated. These include gene duplication, transposable element protein domestication, lateral gene transfer, gene fusion, gene fission, and de novo origination. This complicated talk explains the origin of genes. The human genome contains some 25,000 genes. Where did they come from? How are new genes formed? Before continuing with the Origins Series and The Origin of Cognition, I wanted to take a step back and fill in some holes I left. Other topic I'm considering are: The Origin of The Krebs Cycle, and The Origin of Eukaryotes.
