What are all organisms mostly the same in?
The last universal common ancestor (LUCA) is the most recent organism from which all organisms now living on Earth descend. Thus it is the most recent common ancestor of all current life on Earth. The LUCA is estimated to have lived some 3.5 to 3.8 billion years ago (sometime in the Paleoarchean era).

The last universal common ancestor or last universal cellular ancestor (LUCA) also called the last universal ancestor (LUA) is the most recent population of organisms from which all organisms now living on Earth have a common descent—the most recent common ancestor of all current life on Earth. A related concept is that of progenote. LUCA is not thought to be the first life on Earth but rather the only type of organism of its time to still have living descendants.
