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.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
