Karl Von Linne (or Linnaeus, as he is widely known) was a Swedish biologist who devised the system of Latinised scientific names for living things that biologists use to this day. When he came to{{U}} (1) {{/U}}people into his system, he put them into a group called Homo- and Linne ’ s hairless fellow humans are still known biologically as Homo sapiens.{{U}} (2) {{/U}}the group originally had a second member, Homo troglodytes. It lived inAfrica, and the pictures show it to be covered{{U}} (3) {{/U}}hair.
Modern{{U}} (4) {{/U}}are not as generous as Linne in welcoming other species into Man’s lofty{{U}} (5) {{/U}},and the chimpanzee is now referred to {{U}} (6) {{/U}}Pan troglodytes.But Pan or Homo, there is no{{U}} (7) {{/U}}that chimps are humans’ nearest living relatives, and that if the secrets of what makes humanity special are ever to be{{U}} (8) {{/U}}, understanding why chimps are not people, nor people chimps, is a crucial part of the process. That, in turn, means looking at theDNA、of the two species,{{U}} (9) {{/U}}it is here that the{{U}} (10) {{/U}}must originate.

For those expecting{{U}} (13) {{/U}}answers to age-old questions{{U}} (14) {{/U}}, the publication of the chimp genome may be something of an{{U}} (15) {{/U}}. There are no immediately obvious genes-present in one, but not the other-that account for such characteristic human{{U}} (16) {{/U}}as intelligence or even hairlessness.And{{U}} (17) {{/U}}there is a gene connected with language, known as FOXP2, it had already been discovereD、But although the preliminary comparison of the two genomes{{U}} (18) {{/U}}by the members of theChimpanzee Sequencing andAnalyssisConsortium, the multinational team that generated the sequence, did not{{U}} (19) {{/U}}any obvious nuggets of genetic gold, it does at least show where to look for{{U}} (20) {{/U}}.
