    ... entually clone or study them. Unfortunately attempts to isolate ancient bacteria have been inconclusive. The chief concern in isolating ancient bacteria is the contamination of the sample by modern bacteria through fractures in the amber. Despite the extensive sterilization techniques, scientists cannot be sure whether the bacteria isolated are truly ancient bacteria (Poinar, 1994). For instance, Bacillus subtilis bacteria were cultured from an amber from an amber specimen of a stingless bee from the Dominican Republic, but these bacteria are commonly found in both the alimentary canal of the modern-day stingless bee and in the soil. Also problems arise in extracting the DNA from the sin ...

  • The Greenhouse Effect - 1,125 words
    ... ffect worldwide temperatures dramatically. In 100 years time the average temperature for most parts of the world will increase from between 2 degrees C to 6 degrees C if greenhouse pollution continues at its present rate. (Baines, p. 190) This temperature increase would drastically affect the growth of many different crops and cause the polar ice caps to melt, thus increasing sea levels. If this rise in sea level was to occur many areas would be much more prone to flooding, and generally much deeper floods would be experienced than nowadays. This flooding would happen particularly around coastal regions worldwide, and also along many rivers that flow to or from coastal inlets. The greenh ...

    ... were present to greet the ani- mals as they left the sea. These animals were arthropods: scorpions, spiders, and bugs. Arthropods still outnumber all other species of land animal life except the microscopic. Of concern to us at this time is the evolution 370 million years ago of rhipidistan, the first lungfish, which were the direct ancestors of all higher forms of life: amphibians, reptiles, birds, and mammals. These early lungfish lived in the coastal bogs and estuaries, occa- sionally venturing onto land for brief periods. On the Land By 345 million years ago, rhipidistan had evolved into eogyrinus, the first amphibian and a true land animal. The vertebrates had invaded the land. Amph ...
