My tribe is as follows:

All are black-haired, no identical hairstyles

1 male - 26, no dislikes, but a slight advantage in research
2 females - 1 15yr old, 1 17 yr old - no dislikes, but no skills
2 7 yr olds - a boy & a girl

I wanted time to build skills & food supplies before growing the tribe. The male being slightly older didn't worry me because males can still breed til the day they die. And he had a really cool mohawk, so ... Also - growing a population doesn't require as many males as females, thus the slightly higher # of females.

I put the adult male to researching, 1 female to building, the other to farming & the 2 kids to searching for collectibles & mushrooms.

By the time the 1st hut (after the love shack) was built, & females were ready to have babies, all 3 adults were master builders AND master scientists. And having 2 small children constantly searching for mushrooms allowed me to strictly ration the blackberries w/o risking starvation.
