Spock is the son of Vulcan Ambassador Sarek and Amanda Grayson, who met when Sarek was assigned to earth.

They later married and she moved with him to Vulcan when his assignment on Earth came to an end.

They were living in the city of ShiKahr when Spock was born. Spock was not the first Human-Vulcan hybrid, but he was the first to survive.

Spock had to be removed from Amanda's body and Vulcan scientists performed a lot of subtle adjustments before returning him to his mother's womb where he completed the nine months of gestation before being placed in an artificial womb for a further four months to complete the Vulcan gestation period.
