Louis Leakey b. With his theoretical and paleontological work in the field, he had a considerable impact on the science of early human evolution. In addition to the 20 books and over articles he wrote in his lifetime as well as the multiple fossil and stone tool discoveries that contributed so significantly to our understanding of the field, he was also largely responsible for convincing other scientists that Africa was the key location in which to search for evidence of human origins.

Louis grew up speaking Kikuyu as fluently as English, and at age thirteen he was initiated as a member of the Kikuyu tribe. He later wrote a definitive study of their culture in Leakey began his university career at Cambridge University in , but a rugby injury caused him to postpone his studies.

Fossils are the remains of animals and plants which lived prior to historical times. Their study is a specialised branch of geology known as palaeontology. As fossils are normally preserved by burial in mud and silt, it naturally follows that fossils are found almost exclusively in sedimentary rocks. Rare examples are known of animals found in volcanic rocks where they were trapped and overcome by lava flows or volcanic ash.

There are two major requirements for an organism to be preserved as a fossil:. Flesh is subject to extremely rapid decay, and is rarely preserved in fossils; among the few exceptions are the frozen mammoths of Siberia and Alaska, and a rhinoceros found in oil sands in Poland. Thus, under normal circumstances, only animals possessing hard parts of shell, bone or chitin the hard matter in insects are capable of preservation as fossils.

Rapid enclosure in a protective medium is necessary to protect hard parts from the destructive action of scavengers and the weather. This protection is usually accomplished by burial in waterborne sediments, thus giving aquatic, particularly marine, forms of life the best chance of fossilisation.

What are the 2 ways in determining the age of the fossil fuels??

Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material. The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles. Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon. At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues.

When an organism dies it ceases to replenish carbon in its tissues and the decay of carbon 14 to nitrogen 14 changes the ratio of carbon 12 to carbon

Which is the most abundantly available fossil fuel in India? What are its three not checking the date of expiry before buying the items. (ii) In order to achieve.

Any preserved remains, impression, or trace of organisms that lived in the past is called fossil. Examples include bones, shells, exoskeletons, stone imprints of animals, etc. By determining the age fossil. This called carbon dating. Once the age of fossil been determined, it is easy to gather the information about other past lived organisms. It can be concluded that vertebrates have been slowly originated from invertebrates.

what is the method of radioactive dating and the principle behind the procedure????

What are fossils? How are they formed? Describe in brief two methods of determining the age of fossils.

Fossils may be defined as the remains of the organisms which have been preserved in the form of molds or cast in rocks etc. When a plant or an animal dies, their remains falls on the ground. Over a period of time their body gets covered by sediments brought by rivers, winds etc. These sediments keeps on getting accumulated for over hundreds of years and when that land gets eroded, the fossils can be seen clearly.

Radioactive Dating or Radioactive carbon dating is a technique of finding out the age of organic matters like fossils, wood, leather etc. by.

Claim: all absolute dating utilizes six fundamental biostratigraphic methods fundamental to piece together the age determination of cross-cutting relationships.
