Question

If two different animal species are found to go through equivalent stages of embryonic development until the very last stage, which conclusion would this phenomenon support? (1 point)

Answer 1

Answer: The phenomenon supports that those animals species had a common ancestor.

Step-by-step explanation: The equivalent stages of the embryonic development of such species have retained the homologous structures ascertaining the fact they did have a common ancestor.

The structure can be same or even the function may remain the same at times in certain species. The bone structure tends to be similar. The similarity may end there and exterior of each animal may look totally different and it would be hard to think that they shared a common ancestor.

But later on as they evolved and became different animal species altogether they still retained the homologous structure. Those structures were used for different functions.

e.g. wing of a bat and a human arm

Answer 2

"The two animal species which are very closely related" is the conclusion supported by this phenomenon.

Step-by-step explanation:

The provided hypothesis supports the closely connected existence of the two species, which implies their genomic evidence is very close. Yeah, the knowledge that controls embryonic development is nearly close as well. But that doesn't mean that they're identical. The embryonic growth stages are similar only in the same species. It is special in terms of their generational connection. A family of species called the Hominidae is created by humans, orangutans, chimpanzees, gorillas and their vanished predecessors. Research teams usually accept that many of the living animals in this category, humans are closest to chimpanzees, measuring from anatomy and genetics distinctions.
