Two researchers have recently died who are relevant to evolutionary biology.
Leigh Van Valen, the originator of the “Red Queen Hypothesis” and a proponent of the Ecological Species Concept, died yesterday, John Hawks is reporting. I had some correspondence with him, which makes me glad that I did before he passed.
Edna Ullman-Margalit, whose book on The Emergence of Norms (which dealt with the evolution of cooperation) was a big influence on me, died yesterday also, Leiter and others are reporting.
