Question

Formation of rudimentary eyes shows the evolution in an organism is

• A. Primary stage of evolution
• B. Intermediate stage of evolution
• C. Final stage of evolution
• D. None of the above

Answer 1

The correct option is B Intermediate stage of evolution

A new adaptive feature such as a new type of cell or a new metabolic pathway, a new embryological development that forms eyes, for example, arose due to permutation-combination, multiplication, deletion or metabolic modification of preexisting pathway for related or unrelated processes. Eventually, the light-sensitive spot evolved into a retina, the layer of cells and pigment at the back of the eye. Over time a lens formed at the front of the eye. ... The first animals with anything resembling an eye lived about 550 million years ago.

So, the correct answer is " Intermediate stage of evolution".
