Majel Barrett supposedly came up with her own theories on Number One ("The Cage") when she was preparing for that role, since the Writers' Bible did not elaborate. In her interpretation, the lack of a personal name suggested a colony that used some form of scientific intervention. Many of her ideas were incorporated into DC Fontana's Trek novel, "Vulcan's Glory".
That Number One and Christine Chapel ended up resembling each other is a convenient coincidence!
Can you imagine Spock's surprise when he discovered the Romulan Commander looked just like his OWN FATHER?!
It's funny that the original Mego 8" Romulan action figure was so rare that most people owning one never removed it from the card, but when EMCE/Diamond released their retro-Mego figures we could finally remove the gold helmet to reveal...
a face sculpt of Mark Lenard! (Some collectors are only just noticing now that Mego Target figures are a thing.)
A distant genetic ancestor where physical appearances randomly crops up from time to time.
I had a weird experience at Castle Duart, the Maclean Clan ancestral home, in Scotland. A wall of McLeans and Macleans on a picture wall, with descendants from all over the world - and
none resembled me or my family back in Australia. I was so disappointed.
And then behind me, I noticed a large oil painting looming: a portrait of the
Reverend Jacob Marsham, Canon of Windsor (1759 - 1840), and father of the wife of Sir Charles Fitzroy Maclean, 9th Baronet.
Rev Marsham looks
exactly like my Dad.
