Question

Why would an organism abruptly show up in the fossil record

Answer 1

The correct answer is option C, An organism experienced punctuated equilibrium and rapidly evolved into another organism entirely

The biologist and geologist have not been able to identify the cause of sudden appearance and disappearance of an organism in the fossil record. They then coined the term punctuated equilibrium which supports the concept of lack of information regarding the changing fossil records. The punctuated equilibrium believes that evolution happened suddenly in a very short duration. There are lot of missing links regarding the transitional forms of any evolving organisms which now is used to support sudden appearance of an organism in the fossil record

Answer 2

C. An organism experienced punctuated equilibrium and rapidly evolved into another organism entirely.
