Having a Jolly good time--together! Evolution by cooperative interaction.
What's in a word? "Hybridization" is easy to say (for professors) but carries surprisingly deep meaning from an evolutionary viewpoint. Cliff Jolly's research contributions have included important work and thought on the nature of baboon diversity and interactions. Hybridization among baboon subspecies reflects compatible genes for many different physical and behavioral traits, essentially all traits, each of them complex. Modern developmental genetics has shown that a few general principles characterize the phenogenetic logic by which genes assemble embryos and maintain the complex traits and abilities of organisms, including behavior. How cooperative viability is maintained while complex adaptive traits evolve and populations diverge is a question we can begin to answer more definitively than has been possible before. A careful look leads us to challenge the nature of the Darwinian explanations that have been the standard for more than a century.
