A New Kind of Cell Division

For hundreds of years, there have only been two main types of cell division in animals. But now researchers have identified a new and unexpected kind of cell division that occurs without DNA being replicated. Discovered in zebrafish skin cells, this newly spotted division, called asynthetic fission, could be a temporary measure used when growth is fast to make sure there's enough skin to go around.
