2、e rocks show impression of skin,so that,apart from color;we can buildup a reasonably accurate picture of an animal that died millions of years ago.The kind ofrock in which the remains are found tells us much about the nature of the original land,oftenof the plants that grew on it,and even of its cli
3、mate.2).Nearly all of the fossils that we know were preservedin rocks formed by water action,and most of these are of animals that lived in or near water.Thus it follows that there must be many kinds of mammals,birds,and insects of which weknow nothing.3),There were also crab-like creatures,whose bo
4、dieswere covered with a horny substance.The body segments each had two pairs of legs,one pairfor walking on the sandy bottom,the other for swimming.The head was a kind of shield witha pair of compound eyes,often with thousands of lenses.They were usually an inch or tvvolong but some were 2 feet4),Of
5、 these,the ammonites are very interesting andimportant.They have a shell composed of many chambers,each representing a temporaryhome of the animal.As the young grew larger it grew a new chamber and sealed off theprevious one.Thousands of these can be seen in the rocks on the Dorset Coast.5)-About 75
6、 million years ago the Age of Reptiles was over and most of the groups died out.Themammals quickly developed,and we can trace the evolution of many familiar animals such asthe elephant and horse.Many of the later mammals,though now extinct,were known toprimitive man and were featured by him in cave
7、paintings and on bone carvings.A|The shellfish have a long history in the rock and many different kinds are known.|B|Nevertheless,we know a great deal about many of them because their bones and shellshave been preserved in the rocks as fossils.From them vve can tell their size and shape,howthey walk
8、ed,the kind of food they ate.|C|The first animals with true backbones were the fishes,first known in the rocks of 375million years ago.About 300 million years ago the amphibians,the animals able to live bothon land and in water,appeared.They were giant,sometimes 8 feet long,and many of themlived in
9、the swampy pools in which our coal seam,or layer formed.The amphibians gave riseto the reptiles and for nearly 150 million years these were the principal forms of life on land,in the sea,and in the air.|D The best index fossils tend to be marine creatures.These animals evolved rapidly andspread over
10、 large areas of the world.E|The earliest animals whose remains have been found were all very simple kinds and livedin the sea.Later forms are more complex,and among these are the sea-lilies,relations of thestar-fishes,which had long arms and were attached by a long stalk to the sea bed,or to rocks.F
11、 When an animal dies,the body,its bones,or shell,may often be carried away by streamsinto lakes or the.sea and there get covered up by mud.If the animal lived in the sea its bodywould probably sink and be covered with mud.More and more mud would fall upon it untilthe bones or shell become embedded a

15、the Kirby committee on health care to say nothing of reports from other experts-recommended the creation of a national drugagency.Instead of each province having its own list of approved drugs,bureaucracy,procedures and limited bargaining power,all would pool resources,work with Ottawa,andcreate a n
16、ational institution.42.But“national”doesnt have to mean that.“National“could mean interprovincial provinces combining efforts to create one body.Either way,one benefit of a national”organization would be to negotiate better prices,if possible,with drug manufacturers.Instead of having one province-or
17、 a series ofhospitals within a province-negotiate a price for a given drug on the provincial list,thenational agency would negotiate on behalf of all provinces.Rather than,say,Quebec,negotiating on behalf of seven million people,the nationalagency would negotiate on behalf of 31 million people.Basic

19、ommon Drug Review recommends to provincial lists which newdrugs should be included.Predictably,and regrettably,Quebec refused to join.A few premiers are suspicious of any federal-provincial deal-making.They(particularlyQuebec and Alberta)just want Ottawa to fork over additional billions with few,if
