It's an interesting article (press release?) that makes an interesting point, although I personally realized as I was reading it that I don't think of biological evolution in terms of competition as much as I do differential survival or inheritance rates in some ecological context, possibly changing. Sexual selection seems more directly relevant to the idea of competitive evolutionary processes though maybe?
