Expert Answer:

(a) Archaeopteryx looks like a bird but it has many other features which are found in reptiles. It has feathered wings like those of birds but teeth and tail like those of reptiles.  

Archaeopteryx is, therefore, a connecting link between the reptiles and birds and hence suggests that the birds have evolved from the reptiles.

(b) Evolution may be defined as the formation of wide varieties of organisms which have been evolved from pre existing organisms through their gradual changes (variations) since the beginning of life.
