喙嘴 meaning in English

bill

Yet if large beaks more easily crush seeds , the advantage may tip to the slow breeders
但是，如果大型喙嘴比较容易咬开种子，这样的优势也许会令繁殖慢的雀鸟占上风。
Drop a fast - breeding pair of small - beaked finches and a slower - breeding pair of large - beaked finches onto an island full of food seeds
在一个到处都可以找到种子当食物的海岛上，野放两对雀鸟，一对喙嘴很小但是繁殖速率快，另一对喙嘴大、繁殖慢。
The key is that adaptive fitness can be defined without reference to survival : large beaks are better adapted for crushing seeds , irrespective of whether that trait has survival value under the circumstances
关键在于，定义因适应而产生的生殖成就，不必涉及生存：大的喙嘴比较适应咬碎种子的工作，这与大型喙嘴在鸟儿所处的栖境中有没有生存价值无关。
These days even most creationists acknowledge that microevolution has been upheld by tests in the laboratory ( as in studies of cells , plants and fruit flies ) and in the field ( as in grant ' s studies of evolving beak shapes among gal pagos finches )
现在甚至大多数创造论者都承认，微演化经得起实验室研究的考验（例如以细胞、植物、果蝇完成的实验），以及田野测验（像是葛兰特在加拉巴哥群岛上研究雀鸟喙嘴形状的演化）。
