  • 论发明人的"个体选择"

    对比自然选择,在技术进化过程中,常见的选择来自于社会选择.相比于社会的群体选择,发明人的个体选择同样重要.发明人的选择实现了可表达的新技术基因的形成,影响着技术进化的进程.发明人的选择受其目标准则的影响,与发明人的自身能力素质和外部的社会环境息息相关.要实现国家整体技术水平的提升,必须要重视发明人的工作,应从整体环境营造入手,为发明人提供做出创新性工作的有效空间.

  • Habitat-dependent diversification and parallel molecular evolution: Water scavenger beetles as a case study

    Habitat shift is a key innovation that has contributed to the extreme diversification of insects. Most groups are well-adapted to more or less specific environments and shifts usually only happen between similar habitats. To colonize a pro- foundly different habitat type does not only present ecological opportunities but also great challenges. We used Hydrophiloidea (water scavenger beetles) as a system to study transitions between terrestrial and aquatic environments. We estimated the diversi- fication rate of different clades using phylogenetic trees based on a representative taxon sampling and six genes. We also investi- gated possible evolutionary changes in candidate genes following habitat shifts. Our results suggest that the diversification rate is relatively slow (0.039-0.050 sp/My) in the aquatic lineage, whereas it is distinctly increased in the secondarily terrestrial clade (0.055-0.075 sp/My). Our results also show that aquatic species have a G (Glycine) or S (Serine) amino acid at a given site of COI, while terrestrial species share an A (Alanine) amino acid with terrestrial outgroups. This indicates that habitat factors may create selection pressure on the evolution of functional genes and cause homoplasy in molecular evolution [Current Zoology 60 (5): 561-570, 2014 ]

  • Ecological and evolutionary connections between morphology, physiology, and behavior

    1 Introduction
    Phenotype variation within populations both provides the raw material for and is the product of evolutionary change. An individual's phenotype, defined as the amalgamation of morphology, physiology, and behavior, is highly complex. It has been common to try to isolate each of these aspects of phenotype rather than directly examine their integration. For example, despite the demonstrated importance of single aspects of phenotype for acquiring mates it is well known that signal traits are not evaluated in isolation, but rather in conjunction with associated behaviors, and sometimes with other signal traits (Moiler and Pomiankowski, 1993; Candolin, 2003;

  • 论道德的退化与进化

    道德作为人的工具而偏离甚至危害人本身可谓道德退化,道德退化在历史中表现为三种悲剧,即道德因人而异、道德反客为主和道德因小失大.对这三种悲剧的揭示不会否证道德工具论,只会从另一方面更深入地证明道德工具论,同时还能让我们找到消解道德悲剧与推动道德进化的方法与路径.
