Cichlids are an example of what Mary Jane West-Eberhard calls a “multidirectional radiation” – that is an adaptive radiation that produces a large amount of diversity and specialization of related forms. There are at least 1,500 species of haplochromine cichlids. Within Lake Victoria there are at least 120 species that display a wide variety of behavioral and morphological specializations.

National Geographic mentions an interesting study, appearing in Science, that looks at group composition among Paranthropus robustus . The study looks at sexual dimorphism, dental wear patterns, and taphonomy and concludes that groups in Paranthropus robustus society were structured much like those in gorillas and orangutans. Below the fold you will find a list of links to other coverage of the story. I’m still trying to obtain a copy of the Science article and will have more to say when I have read it.
