Similarities in the early development of chickens and opossums suggest that these organisms share a __________.

I think is common ancestor

Sue is such a troll, literally just a huge troll that changes everything so people get questions wrong. You can literally change your name to anything on here. Ms. Sue could be a 8 year old havin fun on the internet smh.

I disagree.

I think its right....

Ahh -- a difference of opinion. Check your text materials, Claudia.

It is common ancestor. I just had this quiz and got it right.

yea your right @ms sue

You're correct! The similarities in the early development of chickens and opossums suggest that these organisms share a common ancestor. To understand this concept, we can look at evolutionary biology.

To find evidence of a common ancestor, scientists often study embryology, which focuses on the development of an organism from fertilization to birth. By comparing the early stages of development in different species, we can identify common patterns and similarities that point to shared ancestry.

In the case of chickens and opossums, their early developmental stages show similarities. For example, both go through a similar process of cell division and differentiation during embryonic development. They also share common features, such as the formation of a primitive streak and the development of similar organ systems.

These similarities suggest that chickens and opossums inherited their early developmental processes from a common ancestor. Over time, evolutionary changes in their respective lineages led to the differences we see today but with remnants of the shared ancestral characteristics.

In summary, the similarities in the early development of chickens and opossums indicate that they share a common ancestor, likely a primitive organism that gave rise to both lineages.
