Textbook Question
Chapter 52.4, Problem 3CC
MAKE CONNECTIONS → Hawaiian silverswords under-went a remarkable adaptive radiation after their ancestor reached Hawaii, while the islands were still young (see Figure 25.22). Would you expect the cattle egret to undergo a similar adaptive radiation in the Americas (see Figure 52.18)? Explain.
