Answer:

Precambrian, period of time extending from about 4.6 billion years ago (the point at which Earth began to form) to the beginning of the Cambrian Period, 541 million years ago. The Precambrian encompasses the Archean and Proterozoic eons, which are formal geologic intervals that lasted from 4 billion to about 541 million years ago, and the Hadean Eon, which is an informal interval spanning from 4.6 billion to 4 billion years ago. The Precambrian represents more than 80 percent of the total geologic record.

AleksandrR [38]
The answer is <span>A. The two animal species are very closely related.

If the two animal species are very closely related, that means their genome information is very similar and that information for embryonic development is also very similar, but it will not be identical. Stages of embryonic development from the beginning to the end are same only in the same species. In different species, they will differ in lesser or greater extent which depend on how closely this different species are related.</span>
