Think and discuss: Consider the two following statements.a. The theory of evolution states that all living things had a single common ancestor. b. The translation between mRNA and amino acids is the same for all living things. (For example, the mRNA codon CAG codes for glutamine in all living things.)Does the second statement support the theory of evolution? Explain why or why not. If possible, discuss your answer with your teacher and classmates.

Yes, the second statement support the theory of evolution.

The second statement support the theory of evolution because the second statement tells us that translation between mRNA and amino acids is similar for all living organisms. If they have not the same type of translation than it tells us that all living things had not evolved from a single common ancestor and thus does not obey the theory of evolution so we can conclude that the second statement supports the theory of evolution.

Yes, the second statement does support the theory of evolution.

All the organisms on Earth share a common universal genetic code. The genetic code is made of the same nucleotides which are adenine, guanine, cytosine and thymine. The m RNA produced from the genetic code makes the same proteins in each organism. This similarity between the genetic code of every organism on the Earth shows that all organisms might have evolved from a common ancestor. Through evolution, the changes in the sequence of the genetic code caused differences among the organisms.

A spring is a natural discharge point of subterranean water at the surface of the ground or directly into the bed of a stream, lake, or sea. Water that emerges at the surface without a perceptible current is called a seep. Wells are holes excavated to bring water and other underground fluids to the surface.
