But this is more than an environmental or moral tragedy （悲剧）。 Chimpanzee extinction may also have profound implications （含意） for the survival of their distant relatives - human beings. 2 In 1975 the biologist Marie-Claire King and Allan Wilson discovered that the human and chimpanzee genomes （基因组） match by over 98%. Compare this to the mouse， used as model for human disease in lab tests， which shares only 60% of its DNA with us. In fact， chimpanzees are far more similar to humans than they are to any other species of monkey. As well as resembling us genetically， chimps are highly intelligent and able to use tools. These facts alone should be enough to make protection of chimps an urgent priority （优先）。 But there is another， more selfish reason to preserve the chimp. |
