One hypothesis for the origin of life proposes that RNA evolved prior to the appearance of the first living organism. According to this hypothesis, RNA served as the genetic storage molecule and directed the translation of proteins in the earliest living organisms. This hypothesis also suggests that DNA evolved from RNA late in the early history of life. Genetic studies have shown that distantly related species have different DNA replication machinery from one another, but they share similar protein translation machinery.

Does the hypothesis explain the results of these studies?

A. Yes, because if DNA evolved late in life's history, DNA replication machinery could have evolved separately in different lineages.
B. No, because if DNA evolved late in life's history, DNA replication machinery should have been present in the earliest living organisms.
C. No, because if RNA evolved early in life's history, protein translation machinery should have been present in the earliest living organisms.
D. Yes, because if RNA evolved early in life's history, protein translation machinery could have evolved separately in different lineages.

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.
