Why are many of the same genes found in almost all living organisms? (2 points) a: similar genes arose independently under similar conditions. b: there are limited macromolecules involved in dna synthesis. c: all living organisms likely originated from a common ancestor. d: any similarities among genes of different species are due to random chance

The correct answer will be option C.

Explanation:

Living organisms on Earth show a variety of species due to differences in their genetic material but they also exhibit similarity with each other due to the "conserved DNA sequences" present in them.

It is the conserved DNA sequence in organisms which shows that all organisms have evolved from a common ancestor or they all are the lineages of a common ancestor. For example, DNA of humans shows 98 % similarity to the DNA of chimpanzees which shows that they have evolved from the same common ancestor recently.

Thus, option C is the correct answer.
