Let's say we launch the first colony ship to a far system. The colony ship engines fail halfway and the ship drifts for a year across the space. The ship was recovered by drones of an automated ringworld built around a star similar to our Sun and is a massive zoo-preserve constructed millions of years ago, but is still in a perfect state. This ringworld is controlled by multiple AIs programmed to preserve alien species, but the main sentient AI is the true master of the ringworld.
The drones secured ten starving human males inside cryopods.
The AI of the ringworld heals and feeds them, but is unable to communicate with the humans for now. Or maybe the AI doesn't want to communicate with the humans. The humans are transported to an island near one big continent of the ringworld with their minds deleted, but in perfect health.
This artificial intelligence, let's call it Master, takes some DNA of the survivors and with the advanced alien technology tries to recreate the opposite sex, but it fails for whatever reason.
The master doesn't give up. He experiments for one month and succeeds. With some DNA of one of many xeno fauna living inside the ring it wasn't difficult. Master created a non sentient humanoid females with reptilian traits like eyes and some pink scales at the shoulders, neck and back with bioluminescence, designed only to preserve the human race with wide hips and big breasts to feed offspring etc.
Or at least try... The reptilian traits are inherited, but male offspring has less lizard attributes and they are still sentient. The females are non-sentient, but they are very fertile and can be trained to do mid-complex tasks. And they have a strong maternal instinct.
The xeno lizard girls, created from social and intelligent dinosaur-like pack predators, are very territorial and apprehensive with their partners, but also very loyal and affectionate and hunt land and sea prey with their claws. twenty were created first, but only ten survived the competition. They were designed to have a birth-rate of 50% males, 50% females and they choose the partner that they like to live in a monogamous relationships.
With all that info: What kind of culture would this society develop. Let's say 1,000 years have passed and now humans are on the equivalent of early iron age?
Small Additional question: How would the children be educated?
Note : Fire was discovered again in the first decades.
