The existence of ubiquitous genes and proteins (performs the same function in all organisms) strongly support the theory that all life evolved from a common ancestor.  With that in mind, what kind of genes might be evolutionarily conserved and universally found in bacteria, plants and animals? Select one: a. genes that code for the synthesis of ribosomes. b. genes that code for the enzymes of glucose metabolism c. genes that code for the synthesis DNA and RNA polymerase d. all of the above.

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
