The embryos of a bird, a reptile, and a mammal are similar in appearance. how does comparing the physical appearance of embryos of different species support the theory of evolution? a. it shows that these organisms share a common ancestor. b. it provides evidence that these organisms eat the same foods. c. it shows that these organisms share the same habitat. d. it provides evidence that these organisms suffered a genetic mutation.

The correct answer is A. It shows that these organisms share a common ancestor.

Explanation:

In biology, the Theory of Evolution was first proposed by Darwin and Wallace and this explains organisms evolve or change over time which means their genes and physical traits are not static but the result of changes in previous generations mainly influenced by environmental changes that make certain traits prevail over others. In the same way, in this theory, changes in species lead to new species and this implies all living organism and even those that are already extinct have one common ancestor and this was the origin of all species as changes in genes and traits or evolution took place.

This idea is supported with different types evidence and one of this is that different types of animals such as birds, reptiles, and mammals look almost identical in the embryonic stage which shows they share common features but as the embryon develops certain features are shown over others. Therefore, comparing the physical appearance of embryos support the theory of evolution as it shows that these organisms share a common ancestor.

hello

answer: collecting information/data

reason: the student is going around and asking people questions to collect data

i hope this
