例1 在范围广阔的电磁波谱中,能够引起视觉的只是波长为370 nm～750 nm这样很窄的一部分,太阳辐射的各种波长的电磁波中, 也是这部分最强,对这种“巧合”最恰当的解释是( ) (A)太阳辐射的电磁波,是根据人类需要进行的 (B)因为不辐射这种电磁波的“太阳”在优胜劣汰中将被自然淘汰 (C)根据适者生存的原则,只有适应这种环境(只能对这部分电磁波敏感,能引起视觉 Example 1 In a wide range of electromagnetic spectrum, only a narrow part of the wavelength range from 370 nm to 750 nm can be induced, and the electromagnetic waves of various wavelengths of solar radiation are strongest in this part. This is a “coincidence”. The most appropriate explanation is () (A) The electromagnetic radiation of the sun is based on human needs (B) Because the “sun” that does not radiate such electromagnetic waves will be eliminated naturally in the survival of the fittest (C) According to the principle of survival of the fittest Only adapt to this environment (can only be sensitive to this part of the electromagnetic wave, can cause visual
