  1. I find female aggression fascinating. Precisely that human females, as opposed to fruit flies females, are exposed to one another set of DNA-like instructions – culture . Culture that can, for example, tell them that they're anti-thesis of aggression (illustrated at 22:42 here). As a result, often seems to have rather hard time mentally processing instances of their aggressive capabilities or behaviors.

  2. I don’t have a degree in biology so please excuse me if my comments seem inadequate. But I don’t really see the point of benefits for females or males. Wouldn’t any either contribute to the species? Aren’t the manipulators not the genes in the end? The part addressing the benefit seems to imply some intentional behavior on the part of the flies. Isn’t the aggression resulting from the contact with the sex peptide and sperm not simply mechanical? Do you answer the question as to whether more aggressive females are more successful, isn’t the fact that this behavior is generalized the outcome of successful reproduction? It seems to me that even this aggression being an incidental result of the contact between sperm, peptide and the female, this aggression will lead to females to secure more food and so to ensure they’re laying more eggs? Isn’t this the obvious conclusion? Or am I missing something?
