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 (1) 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. (2) the group originally had a second member, Homo troglodytes. It lived in Africa, and the pictures show it to be covered (3) hair.
Modern (4) are not as generous as Linne in welcoming other species into Man’s lofty (5) ,and the chimpanzee is now referred to (6) Pan troglodytes. But Pan or Homo, there is no (7) that chimps are humans’ nearest living relatives, and that if the secrets of what makes humanity special are ever to be (8) , understanding why chimps are not people, nor people chimps, is a crucial part of the process. That, in turn, means looking at the DNA of the two species, (9) it is here that the (10) must originate.
One half of the puzzle has been (11) for several years: the human genome was published in 2001. The second has now been added, with the announcement in this week’s Nature (12) the chimpanzee genome has been sequenced as well. For those expecting (13) answers to age-old questions (14) , the publication of the chimp genome may be something of an (15) . There are no immediately obvious genes-present in one, but not the other-that account for such characteristic human (16) as intelligence or even hairlessness. And (17) there is a gene connected with language, known as FOXP2, it had already been discovered. But although the preliminary comparison of the two genomes (18) by the members of the Chimpanzee Sequencing and Analyssis Consortium, the multinational team that generated the sequence, did not (19) any obvious nuggets of genetic gold, it does at least show where to look for (20) .

Buy energy-efficient products.—Buy new appliances or electronics of the highest energy efficiency rating. New energy efficient models may cost more initially, but have a lower operating (3) over their lifetimes. The most energy-efficient models (4) the Energy Star label, which identifies products that use 20-40 per cent less energy than standard new products. According to the EPA, the typical American household can save about $-400 per year in (5) bills with products that carry the Energy Star.
Switch to compact fluorescent bulbs. —Change the three bulbs you use (6) in your house to compact fluorescents. Each compact fluorescent bulb will keep half a ton of carbon dioxide out of the air over its lifetime. (7) , compact fluorescent bulbs last ten times as long and can save $-30 per year in electricity costs.
Set heating and cooling temperatures correctly.—Check thermostats in your home to make sure they are (8) at a level that doesn’t waste energy. Get an electronic thermostat that will allow your furnace to heat the house to a lower temperature when you’re sleeping and retum it to a more (9) temperature before you wake up.
Turn off the lights.— (10) lights and other electrical appliances such as televisions and radios when you’re not using them. Install automatic timers for lights that people in your house frequently forget to turn them off when (11) a room.
Choose renewable energy.—Many consumers can now choose their energy supplier. If you have a choice, choose an electric utility that uses renewable power (12) , such as solar, water or wind.
Let the sun shine In.—The cheapest and most energy—efficient light and heat source is often right outside your windows. On (13) days, open blinds to let the sun light your home for free. Also remember that (14) entering a room equals passive solar heating. Even on cold winter days, sun streaming into a room can raise the temperature by several (15) .
