Question #N881
The passage discusses the evolution of a species of birds. The author explains that the birds were originally black and white, but they eventually evolved to have red feathers. The author explains that this change was due to a process called natural selection, which means that the birds that were best adapted to their environment were more likely to survive and reproduce. The author cites several examples of how natural selection has shaped other species of birds, such as the peacock's tail feathers and the giraffe's long neck. The author also discusses the importance of biodiversity and the need to protect endangered species.
