In Do Animals Have Culture?, the article defines that
Cultures are those group-typical behavior patterns shared by members of a community that rely on socially learned and transmitted information.
They also say that
Neither evidence of group-typical behavior patterns nor a demonstration that the species is capable of social learning is in itself strong evidence for culture.
I understand group-typical behavior patterns does not implies culture, as the article explained
The term “culture” does not apply to inherited genetic information or the knowledge and skills that individuals acquire on their own.
However, I don't get why not "capable of social learning is in itself strong evidence for culture". If we define that culture as shared behavior patterns that acquired by social learning. How is capable of social learning not implies capable of having culture?
