Answer:
Cuando dos organismos comparten un ancestro común, su código genético tiene que ser similar. El grado de similitudes determina qué tan recientemente han evolucionado los organismos. ... Cuando dos organismos tienen una anatomía muy similar, podrían haber descendido de un ancestro común
Explanation:
The answer is; B
Mutation is one source of variation (in addition to sex and gene flow). Mutations are rare and occur in a small proportion of individuals. However, due to the advantage that the genetic mutation confers to these individuals, their chances of passing the genes to the next generation is higher than that of the general population.
This way, the allelic frequencies of these advantageous mutated genes increase with each generation and eventually become the majority population over time.
