To survive in the cold: the evolution of reduced decay rate in a bacteriophage [0.03%]
在寒冷中生存：细菌噬菌体衰减率降低的进化

Viruses typically have high decay rates (mortality rates outside hosts), and applications of phage viruses for combating harmful bacterial in clinical and agricultural contexts would favor slow-decaying phage materials. There is evidence fo...

A central challenge in comparative biology is linking present-day trait variation across species with unobserved evolutionary processes that occurred in the past. In this endeavor, phylogenetic comparative methods are invaluable for fitting...
Latitude and communal living are associated with the evolution of joint territory defense in New World songbirds [0.03%]
纬度和群居生活与新世界鸣鸟共同防御领地的进化有关

There is great variation across species in how many individuals participate in territorial defense. Here, we test the hypotheses that joint territorial defense by pairs or family groups is more common in songbird species that (1) nest in tr...
The inhibitory cascade model and evolution in segmentally organized tissues [0.03%]
抑制级联模型和分节组织中的进化现象
Benjamin M Auerbach,Charles C Roseman
Benjamin M Auerbach
The inhibitory cascade model (ICM) of morphogenesis is an effort to link development to the production of variation, which can influence evolutionary trajectories. The ICM proposes that serially developing features, such as molar teeth, are...

There have been many recent discussions of the Fundamental Theorem of Natural Selection, with an emphasis on its mathematical accuracy. It is argued here that, despite the mathematical problems that have been uncovered, it still has utility...
Specialization of male reproductive tactics correspond with large gonads and small brains [0.03%]
雄性的生殖战术专业化伴随着大生殖腺和小大脑的现象

Sexual selection has strong effects on gonad size, which has been proposed to shift energetic allocations, resulting in concomitant decreases in brain size. However, mixed findings leave it unclear whether negative correlations reflect dire...
Exploring the stability of sex chromosome systems in Anolis and other iguanas [0.03%]
求解蝘蜓和其他蜥蜴中的性染色体系统稳定性问题

Marie Altmanová et al.
Sex determination was once thought to be unstable in ectothermic vertebrates, but several highly diversified groups of non-avian reptiles, such as iguanas sensu lato (Pleurodonta), appear to have conserved sex chromosomes. However, this sta...
Adaptation at the edge: Patterns of local adaptation and genetic variation during a contemporary range expansion [0.03%]
边缘扩张适应：扩张边缘地带局部适应和遗传变异的格局分析
Eliza I Clark,Dan W Bean,Ellyn V Bitume et al.
Eliza I Clark et al.
During range expansion, differences in traits can evolve between populations at the core and expanding edge of a range. While theory and experimental work have focused on range expansions across uniform environments, natural range expansion...
Modular reorganization of the trilobite Lonchodomas chaziensis demonstrates mosaic patterns of phenotypic change underlie metamorphosis [0.03%]
棱皮蜱（Lonchodomas chaziensis）的模块化重组表明表型变化的马赛克模式构成了变态的基础

Some trilobites underwent drastic morphological transformations through their development. The Ordovician trilobite Lonchodomas chaziensis transformed, in a single molt, from a globular protaspid larva to a drastically different adult-like ...
