Similarities in the early development of chickens and opossums suggest that these organisms share a________.
common ancestor???
It could be, but I didn't find anything online to substantiate this. What does your text say?
It said the same exact thing! I SUBMITTED MY TEST SO NOW MY TEACHER IS GOING TO CHECK IT THEN i LL LET U KNOW WHAT HAPPENED if I REMEMBER:)!!
Srry bout caps:) Just saw!
Yes, you are correct. The similarities in the early development of chickens and opossums suggest that these organisms share a common ancestor. To understand why, we need to learn about the concept of common ancestry.
To determine if two organisms share a common ancestor, scientists analyze their similarities and differences. One way to do this is by comparing their developmental stages. The process by which an organism develops from a fertilized egg into an adult is called embryonic development.
Chickens and opossums are both vertebrates, which means they belong to the same group of animals that have a spinal column or backbone. During their early embryonic development, both chickens and opossums show similar characteristics and structures, such as the formation of a neural tube, limb buds, and a tail. These similarities indicate that they share a common evolutionary history and likely descended from a common ancestor.
By studying patterns of similarity in embryonic development and other traits, scientists can infer relationships between different species and their evolutionary history. This information helps biologists to understand the diversity of life on Earth and how different species are related to each other.
