important to see well to develop an acute sense of smell, in the 【M1】______
course of evolution members of the primate line has acquired large 【M2】______
eyes while the snout has shrunk to give the eye an unimpeding view. 【M3】______
Of mammals only humans and some primates enjoy color vision. The red
flag is black to the bull. Horses live in a monochrome world. Light visible to
human eyes, therefore, occupies only a very narrow band in the whole 【M4】______
electromagnetic spectrum. Ultraviolet rays are invisible to humans though
ants and honeybees are insensitive to them. Humans have no direct perception 【M5】______
of infrared rays like the rattlesnake that has receptors tuned into 【M6】______
wavelengths longer than 0.7 micron. The world would look eery different 【M7】______
if human eyes are sensitive to infrared radiation. Then instead of the darkness 【M8】______

选项
答案
therefore改成however
解析
