1.	With the help of given information write your comment on evidences of evolution. Mammals have fore limbs as do birds, reptiles and amphibians. The basic structure of the limbs is similar, though it has been modified to perform different functions.
Answer» 1. The given information gives the evidences of evolution. 2. Mammals. birds, reptiles and amphibians all these have forelimbs which have similar basic structure. 3. But they are modified to perform different functions. 4. This indicates that all the vertebrates have evolved from a common ancestor. These organs are called homologous organs. This type of evolution is called divergent evolution. 5. In case of bat (mammal) and bird the designs of the two wings, their structure and components are different. 6. They look similar because they have common use for flying, but their origins are not common. 7. These organs which are structurally different but functionally similar are known as ‘Analogous organs’. This type of evolution is called “convergent evolution”. 8. There are remarkable similarities in the embryos of above mentioned animals even in their limb formation. These are called embryological evidences.
