How Unix made it to the top
Yep, XNU is Mach microkernel + FreeBSD kernel. Some features of XNU are even ported back to FreeBSD kernel. IMHO, that is enough to draw direct connection from XNU to original UNIX (without ™), unlike Linux kernel.

Mach microkernel + FreeBSD userland.... not kernel.
BSD is a 'personality' layer.
