Basing their judgment on the fact that different local populations of cowbirds of the same species sing in styles particular to their populations, ornithologists have concluded that the cowbirds' singing styles are culturally acquired, rather than genetically transmitted.Which of the following, if true, would most strengthen the conclusion drawn by the ornithologists? There are more similarities than differences among the songs. Younger female cowbirds are not proficient at singing and have been observed watching their mothers sing for years before themselves starting to sing. The songs of one species of cowbird lack the vocal range and ornamentation characteristic of the songs of all other species of cowbird. Local populations of cowbirds seldom come into contact with each another. It is well known that the mating dances of some birds are learned rather than transmitted genetically. Review Answer
