There were many other clans, too.
Some of them were named after wild animals, and some were named after plants.
All the people lived in clans, for it was the best way to live at that time.
There were enough men in each clan to protect it from wild beasts.
There were enough women to do the household work.
There were many children, too.
But there was room enough in the cave for all, and they lived as if they were one large family.
Each child in the clan was given a name, which was changed when he became full grown.
The name of one of the girls was Brighteyes.
Brighteyes called every man in the cave her father, and she called every woman her mother.
