What is the meaning of tuesday's child is full of grace?

"Full grace" means 'favored by God', or those who are agnostic it means very very lucky. Angel Gabriel tells the Virgin she is full of grace, as she is chosen among all other women to bear Christ Jesus.   

During the paleolithic, hominins grouped together in small societies such as bands, and subsisted by gathering  plants  and fishing, hunting or scavenging wild  animals. the paleolithic is characterized by the use of knapped stone tools, although at the time humans also used  wood  and bone tools.

Hope this will !
