Hace aproximadamente 250 millones de años ocurrió la extinción masiva del Pérmico-Triásico, un evento en el cual murieron hasta el 96 por ciento de las especies marinas y un porcentaje similar de las terrestres.

Answer:
Explanation:
have a good day but ion know the answer..
Answer and Explanation:
Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.
