Sexual selection, a mechanism of evolution that can drive the appearance of bright feathers and elaborate horns, is often assumed to operate largely among males.【B1】________a fresh look at the data suggests it is more widespread among females than many researchers【B2】________
It was Charles Darwin who【B3】________suggested that males often compete【B4】________other males for females to mate with-which he argued could help explain why, for instance, some male birds have【B5】________bright plumage【B6】________this makes them a more obvious【B7】________for predators.
More recently, biologists have begun to realize that sexual selection【B8】________widely among females too, although Tim Janicke at the Centre for Functional and Evolutionary Ecology in France and his colleagues say it is still assumed to be a【B9】________peculiarity.
Now, Janicke and his colleagues have【B10】________evidence of female-orientated sexual selection in 72 species across the animal kingdom from scientific literature【B11】________between 2015 and 2020. They say the analysis suggests that【B12】________for mates in females should be considered the【B13】________
" We believe that our view of how we see sex differences in【B14】________, and also sexual selection in particular, is still very【B15】________towards males," says Janicke.
The analysis shows evidence of female sexual selection in a broad【B16】________of animals.【B17】________, in various species of pike, it is the female that is more colorful, with more【B18】________to attract mates. And in some tropical wading birds, such as jacanas, females fight each other【B19】________the attention of the highest quality male. The researchers invite investigators to spend more time studying such behavior in females.
" Sexual selection is a process that may【B20】________any sex," says Ingrid
at Uppsala University in Sweden.

选项
A、context
B、completion
C、competition
D、competence
答案
[C]
解析
本题考查名词辨析。四个选项分别为[A]context“背景,环境,上下文”;[B]completion“完成,结束”;[C]competition“竞争,比赛,竞赛(多指体育运动中的各种比赛、角逐,也可指知识、技巧等方面的竞赛);竞争者,对手”;[D]competence“能力,胜任:技能,本领”。根据上文female-orientated sexual selection可知,这里要表达的是雌性对雄性配偶的“竞争”,故选项[C]正确。
