From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Your point is well taken and I appreciate expanding my knowledge on this a bit, but I don't think that it is that cut and dry. Mach, the kernel from which both is not Unix. Mach is basis for XNU (X is not Unix, sound familiar). From the screenshots from Wikipedia, pretending that BSD is not embedded within MacOS is just trying to obfuscate things. The Mach virtual memory manager for instance is in FreeBSD, so it goes the other way around as well.
