Peter and Rosemary Grant have studied the gene-culture transmission of birdsong in Charles Darwin's finches, Geospiza fortis and Geospiza scandens. What evidence from their studies illustrates the "culture" part of the transmission and what evidence illustrates the "gene" part of this coevolutionary relationship?

The cultural part of the transmission happens when the child learns the song from the father.

The gene part of co-evolutionary relationship happens when the females mate only with the males who sing the song produced by males of their own species.

Explanation:

The gene is known to a heredity unit that is transferred from a parent to the child and the gene plays a major role in determining the characteristic of the child.

The gene-culture transmission of birdsong illustrates that the songbirds usually learn the songs from other birds of their gene.
