B.seasonal migration
C.brood parasistism
D.connecting links
Solution
Adaptive radiation represents evolution of new forms in sevral directions from the common ancestral type. In 1831 Darwin got an opportunity to travel by H M S Beagle for a voyage of worls exploration. Beagle sailed to the Galapagos Islands, here Darwin found a living laboratary of evolution. The common birds of Galapagos Island, the finches were markedly different from the finches of man land. The closely related species of finches had beaks of different shapes and size and adapted for feeding on completely different diet showing adaptive radiation.
The transitional fossil forms which show characterstics of two different groups of living animals are called connecting links, eg, Archaeopteryx, Seymouria etc.
