Evolution

Lora Tiptoed across the bedroom stepping gingerly from one rug to another, avoiding the chilling touch of the hardwood floor. She fumbled in the closet and finally slipped her cold feet into sensible blue leather house-slippers. The heels clicked softly on the hall floor. She raised the window shade in the bathroom, and the half-light of the early morning added cheerless rays to the cold room. Lora gasped at the shock of cold water on her face, and her hands shook as she drew curlpins from her hair. She combed her hair hurriedly, and its electricity bristled about her shoulders as she drew on a blue flannel robe. It was not until she reached the basement stairs that she remembered. I didn\u27t hear the trap click, last night. He probably never came near it. Silly -to have to set a trap for a mouse when you have a cat. Guess the cat\u27s too well-fed to want a mouse. I certainly gave him plenty of chance to catch it. Hate to set a trap, for anything, she thought. She put off inspecting the trap and busied herself with coaxing the few still-glowing coals to give crackling life to the fuel she shoveled briskly into the furnace. Satisfied with her efforts at last, she stopped to wash her hands again at the basement faucet, then turned to the second basement room. Hate to catch anything in a trap. Oh well, he probably never came near it

Evolution: functional evolution of nuclear structure.

The evolution of the nucleus, the defining feature of eukaryotic cells, was long shrouded in speculation and mystery. There is now strong evidence that nuclear pore complexes (NPCs) and nuclear membranes coevolved with the endomembrane system, and that the last eukaryotic common ancestor (LECA) had fully functional NPCs. Recent studies have identified many components of the nuclear envelope in living Opisthokonts, the eukaryotic supergroup that includes fungi and metazoan animals. These components include diverse chromatin-binding membrane proteins, and membrane proteins with adhesive lumenal domains that may have contributed to the evolution of nuclear membrane architecture. Further discoveries about the nucleoskeleton suggest that the evolution of nuclear structure was tightly coupled to genome partitioning during mitosis

The evolution of social norms

Evolutionary game theory provides the tools to analyze which strategies, or patterns of behaviour, emerge over time through a process of adaptation. Social norms can be defined as patterns of behaviour with certain characteristics. Evolutionary game theory thus provides one perspective on how social norms are formed and maintained. Prisoner's dilemma games can be used to study the conditions under which cooperative norms emerge. Bargaining games can be used to address the formation of fairness norms. However, being more congenial to analyzing norms that somehow focus on material payoffs, it is not a given that evolutionary game theory can adequately address norms focusing on rights or virtues.Evolutionary game theory Social norms
