Why are Cilia Described as an Example of Unity Underlying

Question

Why are cilia described as an example of unity underlying the diversity of life?
A)Cilia are cells that function in locomotion.
B)Humans and Paramecium both share the same architecture of their cilia.
C)Cilia have an elaborate system of tubules.
D)Cilia provide motility to all the cells on which they reside.
E)Imprints of cilia have been found in the fossilized remains of prokaryotes.

Accepted Answer

Cilia are present in a diverse range of organisms, from humans to single-celled organisms like Paramecium. Despite their variations in size, shape, and function, cilia share a fundamental structure, indicating a common evolutionary origin. Therefore, cilia demonstrate how different species can have similarities due to a shared ancestry, despite looking different or functioning differently.
