Richard Dawkins - The Selfish Gene - Meet the author

I think this video is not really specific. I am reading the book but I do not understand what it has to do with Ortodox but the only thing I understood was the alturism and the selfish genes that we talked about that before. I did not know the book was so old and it is really confusing to me, and most of all that he would write it the same way after so many years and so much new science appearing in the world.
