In a 1977 article in Science, a botanist reported the strange case of the Tambalacoque tree (Calvaria major) of the Mauritius Islands in the Indian Ocean. All of the trees appear to be hundreds of years old and date, as seedlings, to a time before the extinction of the dodo bird. The seeds of Calvaria are very hard and apparently needed to pass through the digestive tract of the dodo bird before they would germinate. Therefore, when there were no more dodo birds, no more young Calvaria trees germinated. Luckily, foresters can artificially scarify the seeds and germinate new trees now that they know this. 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.
