In a 1977 article in Science,a botanist reported the strange case of the Tambalacoque tree (Calvaria major) from the Mauritius Islands in the Indian Ocean.All of the trees appeared to be hundreds of years old,so their seedlings date back prior to the extinction of the dodo bird.The seeds of Calvaria are very hard and needed to pass through the digestive tract of the dodo bird before they would germinate.When there were no more dodo birds,no more young Calvaria trees germinated. The relationship between the dodo bird and the Tambalacoque tree is an example of

A) micropropagation.
B) spontaneous dispersal.
C) coevolution.
D) genetic engineering.
E) vegetative propagation.
