They're not an offshoot but are full fledged brothers with only a slight difference. Vulcans have telpathy and mind control powers and the Romulans don't.
Nope - the issue in "The Enemy" wasn't species intercompatibility, but that of individuals, inside and across species. Most Romulans might have been incompatible with the poor patient, too...Remember, blood transfusions from Vulcans don't work on Romulans.
It was the late Robert Justman who proposed a Klingon soldier on the Enterprise as a visual symbol of how much things had changed since TOS. Roddenberry liked the idea, and so Worf was born...I think GR didn't even want Klingons and Romulan but someone twisted his arm. Must have been Berman.
