No, the size of the genome has not changed, but the number of genes we thought it contains certainly has. After lots of double checking, there are fewer known protein coding genes today (~19,000) than there were when the human genome was first published, and even that...
Science advances in fits and starts, and it sometimes takes a detour onto a dead-end road. Bacteria represent one of those roads. Studying bacteria gave us a sense that we could easily figure out biology, that there was a direct connection between genes and behavior,...
