SIETAR Follow-up: Genes, memes, temes. Susan Blackwood on TED

As a follow up to Doug Stuarts SUSA workshop,  "Shaking the Interculturalists Paradigm: Considering Consciousness and Cultural Evolution," I would like to offer for discussion this short presentation by Susan Blackwood, that appeared on TED. It takes us from Darwin through Dawkins and beyond and is, I believe, significant for how we see culture being transmitted. The challenges I perceive and would like to discuss: 

1. How does this help us in learning and teaching about cultures?
2. How does this challenge and perhaps refine our view of the world and our personal, psychological and perhaps theological perspectives?
