The color of animals is by no means a matter of chance; it depends on many considerations, but in the majority of cases tends to protect the animals from danger by making it less outstanding Perhaps, it may be said that if coloring is mainly protective, there ought to be fewer brightly colored animals. . The kingfisher itself, though so brightly colored, is not easy to see.
. Thus, for instance, the lion, and the wild donkey are all sand—colored. “Indeed, in the desert, neither trees, brushwood, nor even undulation (起伏) of the surface afford the slightest protection to its enemies..” says an expert.
The next point is the color of the mature caterpillars(毛虫), some of which are brown. This probably makes the caterpillar even more outstanding among the green leaves. What would you do if you were a big caterpillar? Why, like most other defenceless creatures, you would feed by night, and lie hidden by day. . When the morning light comes, they go down the stem of the food plant, and hide among dry sticks and leaves around the ground, and it is obvious that under such circumstances the brown color really becomes a protection. While we may say as a general rule that the large caterpillars feed by night and hide by day, it is by no means always the case that they are brown: some of them still remain green., and that the brown color is a later adaptation.
A. So do these caterpillars
B. Therefore, the color of the animals is bright
C. We can say that they formed a good habit
D. Desert animals are generally the color of the desert
E. We may conclude that the habit of hiding themselves by day comes first
F. However, there are some cases where vivid colors are themselves protective
G. So the color of birds, snakes and even smaller animals, is of one uniform sand color
