When life first originated on Earth. The structure is simple, uncomplicated life gradually changed over time. Changes slowly towards more complex structures and new ideas that underpin the evolution of life has inte educational and discussed by many scientists as the two pillars of the La Marc (Lamark, c. Prof. 1744-1829) of the proposed rule and not the organs of living things (Law of use and Disuse) and the law of inheritance emerging (Law of inheritance of acquired charcteristics) This concept is. to death by a pair Weir (Cuvier) in the late 19th century, later Augustus Wise Man (August Weismann) has pointed out the importance of Royal Palm cytoplasm (Germplasm) and certain characteristics. which is transmitted by heredity About evolution is not yet very widely. Until the year 1859, Charles Darwin published the document "The Origin of species) released the knowledge about the evolution of life is more acceptable. In summary, the concept of Darwinian follows
: 1. creatures of all kinds will increase a geometric progression. Than is usually made up of children born than to live breeding the next
two. Life must fight to survive
three. All living species are inevitably variable
4. The cyclical nature of heredity have several generations. New Life
geological time table and evidence about the evolution of life
tables geological time (geological Time Tabale)
education about evolution. Need to know the story of life in the past. And geological condition of the world It will help in predicting temperatures. Geography and distribution of various creatures have geologists needed to calculate the age of the Earth. And the age of the fossils Use a Turkish Bath, a radioactive element that can be converted to other elements in the early threat of elements such as urea, aluminum will gradually turn into a lead. The rate is only 1 g of urea, aluminum is 0.5 grams of enriched uranium spent 4.6 billion (4.6x109) or a half Chavit (harf-life) was 4.6 billion years old, so the ratio of uranium to lead is found. In shale It allows to calculate the age of the rocks. The rock type was not always radioactive. Therefore, to find fossils older than 30,000 years old commonly used method of measuring the radioactivity of carbon (C14), which occurs naturally C14 is absorbed into the body of the living dead, although it remains. This fossil is C14, which geologists to measure the amount of C14 C14 has a half life of 5560 years, when calculated, you will know that life in the old era or any era or period. Or even when a few million years ago.
