Male bowerbirds construct elaborately decorated nests, or bowers. Basing their judgment on the fact that different local populations of bowerbirds of the same species build bowers that exhibit different building and decorative styles, researchers have concluded that the bowerbirds' building styles are a culturally acquired, rather than a genetically transmitted, trait.
Which of the following, if true, would most strengthen the conclusion drawn by the researchers?
There are more common characteristics than there are differences among the bower-building styles of the local bowerbird population that has been studied most extensively.
Young male bowerbirds are inept at bower-building and apparently spend years watching their elders before becoming accomplished in the local bower style.
The bowers of one species of bowerbird lack the towers and ornamentation characteristic of the bowers of most other species of bowerbird.
Bowerbirds are found only in New Guinea and Australia, where local populations of the birds apparently seldom have contact with one another.
It is well known that the song dialects of some songbirds are learned rather than transmitted genetically.
⚠️一种雄性鸟会建筑一种特别的巢穴，并且同一物种的不同地方建筑的风格都不一样；科学家推断这不是由于先天性的，而是文化熏陶的，问加强
a 被研究的当地鸟的population的相同点比不同点多（无关）
b 雄性鸟是看了长辈很久以后才学会的这种筑巢方式（保留，提到了是后天学习）
c 某一种鸟和大多数的鸟建筑风格不相同（虽然看上去好像有理，但是某一种是哪种？大多数都是一样的反而支持了是先天性的，不选）
d 这种鸟只在那里和那里发了，并且他们很少交流（没有交流，风格又不一样，有可能是基因，又有可能是文化，说不清，不选）
e 无关选项
注意，一定要看到这个重点“culturally acquired“ 这个表明是文化熏陶，文化习得的。关键是”习得“而”文化“是用来修饰”习得“的。看到”习得“很自然就选B
