Answer:
the given evidence is analogous structure
HOPE THIS HELPS YOU
Answer:
1. Embryology 2. Homologous structure 3. A modified structure is seen among different group of descendants
4. Biochemistry 5. Analogous structure 6. Vestigial structure.
Explanation:
1. Embryology is the study of development of complex organisms from single celled fertilized eggs with the consequent generation of tisues and organs. So tail and pharyngeal pouches seen in vertebrates in early development is included in Embryology.
2. These forelimbs have different functions in different animals but they have similar skeletal structure. Hence they are analogous organs.
3. In a blind fish the eyes are non-functional, but in other groups of fishes the eyes are functional, i.e the eyes are modified.
4. Study of DNA and RNA means actually comparing the genetic parameters of organisms to establish their evolutionary relationship or relatedness with each other. It is a part of biochemical sudies.
5. Wings of birds and butterflies perform same function of flying but are of different strucure. So they are analogs of each other.
6. During human evolution, there are organs that were in previous ancestors but are now functionless or retainvery little function. Yet they remain in their rudimentary form inside the body. These are vestigial organs.
