This is a simplified diagram of unix history. There are numerous derivative systems not listed in this chart, maybe 10 times more! In the recent past, many electronic companies had their own unix releases. This diagram is only the tip of an iceberg, with a penguin on it ;-).

Warning : it seems that Adobe Reader has some problems reading the large plotter version of the Unix History chart, but happily you can use another PDF viewer for this task. By the way, if you are on macOS, just use Safari :-)
Here is theChangeLog of this history.
Note 1 : an arrow indicates an inheritance like a compatibility, it is not only a matter of source code .
Note 2 : this diagram shows complete systems and [micro]kernels like Mach, Linux, the Hurd... This is because sometimes kernel versions are more appropriate to see the evolution of the system.
Note 3 : I have now apage where I explain how I build this chart.
