Chapter 1, Problem 4P

All life shares DNA as the hereditary material. From an evolutionary perspective, why do you think this is the case?

Blurred answer
Students have asked these similar questions
DNA is responsible for your phenotype, but to what extent? How much, if at all, do environmental factors play a role? Can you find examples (remember keep your sources academic)?
First there was the RNA world, and now we have a DNA world. Why would natural selection favor the transition to a DNA-based world?
Our DNA is subject to mutations on a daily basis. Why do most mutations that occur in the genome of organisms escape detection and not elicit a deleterious effect? Why does the child of someone with cancer not necessarily develop cancer? Is it reasonable to state that mutations are essential to the evolutionary process?
