[bicicleur 2]

the best is a combination of local developments which are frequently shared via social networks
but to much social interaction delays new developments

at least, according to this study/experiment :

Insights into this process can be gained by studying the few remaining hunter-gatherer societies, such as the Agta people, who live in the Philippines. An international research team has now investigated the social network of Agta hunter-gatherers to shed light on the evolution of culture. The study was led by Andrea Migliano and Lucio Vinicius from the Department of Anthropology of the University of Zurich as well as Federico Battiston from the Central European University in Budapest.

I think that's right.

In terms of comparisons with other species I think language is another huge factor.
