Darwin is the UNIX technology-based foundation of Mac OS X. Darwin integrates several technologies. Among the most important are 4.4BSD-based operating-system services (built on the Mach 3.0 microkernel), the I/O Kit, networking facilities, and support for multiple integrated file systems. Developers can use Darwin to port UNIX/Linux applications and create kernel extensions.
In addition to being part of Mac OS X, Darwin is a standalone, BSD-based operating system. (BSD, short for Berkeley Software Distribution, is a family of UNIX variants descended from Berkeley’s version of UNIX.)Darwin is also occasionally used to refer to the Darwin Streaming Server, also known as the QuickTime Streaming Server (QTSS).

How is Darwin’s Tree of Life compared to ancestral lines of living species?

The Tree of Life was not Darwin's. In fact, it was very familiar to natural historians (as biologists used to call themselves) in the decades before Darwin. However, Darwin showed that the Tree of Life was more than just a static representation of similarities and differences between taxa. He showed that it was a representation of the evolutionary process with the tips of the branches representing modern species and forks in the branches representing previous divergences.
