The tangled bank of amino acids
The use of amino acid substitution matrices to model protein evolution has yielded important insights into both the evolutionary process and the properties of specific protein families. In order to make these models tractable, standard substitution matrices represent the average results of the evolutionary process rather than the underlying molecular biophysics and population genetics, treating...
متن کاملThe Tangled Bank: an introduction to evolution
He lies there on the cover, a large mischievous fishy grin on his face, but with his un-fish-like neck and weight-bearing elbows flexed, as if ready to take a quick dash across an exposed rock as imagined by Gary Larson in a Far Side cartoon as a Great Moment in Evolution. However Tiktaalik roseae probably never did dash out on land, this proto-tetrapod most likely lived its whole life in shall...
متن کاملSymbiont genomics, our new tangled bank.
Microbial symbionts inhabit the soma and surfaces of most multicellular species and instigate both beneficial and harmful infections. Despite their ubiquity, we are only beginning to resolve major patterns of symbiont ecology and evolution. Here, we summarize the history, current progress, and projected future of the study of microbial symbiont evolution throughout the tree of life. We focus on...
متن کاملMate Choice: Charting Desire’s Tangled Bank
Choosing a mate requires a way to turn sexual arousal into sexual action. A recent paper identifies a hormone receptor that acts as a molecular gatekeeper in reproductive decisions. Focusing on mate-choice mechanisms may clarify longstanding evolutionary puzzles in sexual selection and speciation.
متن کاملEquilibrium Bank Runs Revisited
In a Diamond and Dybvig (1983) environment, Green and Lin (2003) take a mechanism design approach and show that a bank run equilibrium cannot exist. Peck and Shell (2003) generalize their economic environment and show that it can. The bank run, however, does not emerge because of modifications to the economic environment but rather because the mechanism that implements allocations is not an opt...
