1. I have read and studied this paper.

2. Connor's scientific reports always remind one of the efforts required to obtain some data sets.

3. As interesting and significant is this and related papers from The Connor Lab are, one needs to know more about the phenomena described for even an elementary grasp of how this study's findings might relate to the evolution of mammalian socio-sexual behavior & architecture.

4. I am not convinced that the bottlenose dolphin society, as described in this publication, is unique to mammals.

5. I am not convinced that "record-keeping" as a precursor to and selective pressure for the evolution of "big brains" is as important as Connor and Dunbar seem to think.

6. As a behavioral ecologist, I am suspicious of propositions about the evolution of socio-sexual behavior & architecture that fail to integrate ecological factors.

7. I am impressed with by the degree to which bottlenose dolphins exhibit facultative decision-making.

8. I link one of my blogposts providing a brief overview of current attempts to understand socio-sexual evolution (SSE):
