One interesting way to look at this. The first commit from freebsd for ls.c is: Added Thu May 26 06:18:55 1994 UTC (21 years, 2 months ago) by rgrimes Original Path: vendor/CSRG/dist/bin/ls/ls.c File length: 13099 byte(s) BSD 4.4 Lite bin Sources The last commit apple has is: Modified Fri Jun 3 11:05:58 2005 UTC (10 years, 2 months ago) by dd So apples version is almost closer in time to the original 4.4 sources as to the current version.
