By using data from bird species and phylogenetically controlled analyses, we show that cooperatively breeding species have more male-biased ASRs than non-cooperative species. Despite the importance of ASR in population biology, biodiversity conservation, and breeding system evolution, the origins of ASR biases remain unclear. Because, like my mother, they feel they already know everything they need to "naturally" and if they don't - then something is wrong. My experience as an evolving adult woman, as a sexologist and as an educator has made me highly motivated to cultivate a list of resources that might be a great starter kit for most people interested in exploring adult sex education.
