No. Ioka's chief is the strongest one of all. Ayla proved to be the strongest, so she became chief. Of course, she resigned when she ran off with Crono to help kill Lavos.
On that subject, there's an interesting line in CTDS that I don't remember... Somebody, either Ayla or one of the 65M BC villagers says that if Ayla becomes pregnant, she loses her place as chief. Presumably simply for the safety of mother and child, but seems a bit harsh.
Also, if anyone can confirm what happened in the SNES version for me regarding something, my mind would be eased: With Ayla in the party, after getting the shard of the Rainbow Shell during the trial and after Marle reads the note from her mother, Ayla has some amusing things to say about motherhood... and then seems to actually feel Marle's breasts and note that she's "too small" to have lots of children. It just uses the "one arm extended" pose, but close enough for her hand to touch Marle's, er, chesty region.
Marle doesn't respond, presumably struck dumb.
Anyway, I really don't remember that pose being there, or how it would have been explained.
