Your statement about wolves and their social organization is mostly accurate. Here’s a slight rephrasing to enhance clarity and flow:
Wolves share similarities with humans in their social organization. A wolf pack may consist of up to twenty wolves. By three weeks of age, wolf pups are capable of playing. Most packs are led by an adult male and an adult female. The average size of a wolf litter is around four pups.
