The order in which DNA is copied during the cell division process reflects the evolutionary history of living beings: the oldest genes are copied first, and afterwards the genes that appeared later
The authors propose an original model that would explain how regions of the genome that are copied later on facilitate the birth of new genes with specific functions in tissues and organs

This is an “old” paper, but I think it is worth promoting again the model of gene birth and evolution that we proposed 🙂
