The organic remnants of the past life forms preserved on the sedimentary rocks in the earth is called fossils. They are the best and direct evidences of organic evolution. The age of fossils is calculated by radio-carbon dating and many other methods, which tells us about the era when the life form were alive. Fossils are of many types, like: Actual remains like the cryopreserved Woolly mammoth (of Siberia) or insects preserved in amber. Petrified plants and animals. Skeletal elements like bones, teeth, etc. of an animal. Moulds are the hardened encasements formed in the outer parts of organic remains which later decayed leaving cavities. Casts are hardened pieces of mineral matter deposited in the cavities of moulds.

A clone is a group of individual that are genetically identical. Clones are produced by asexual reproduction or by inserting a nucleus from a mother cell to the donor egg cells. Dolly was the first animal to be cloned.

Antibiotics are the substances produced by microorganisms that kill or inhibits the growth of harmful microorganisms and destroys it. These inhibit the synthesis of enzymes required for nucleic acid metabolism or protein synthesis. They also act by disrupting the cell wall or cell membrane of pathogens. Antibiotic was by chance discovered by a bacteriologist, Alexander Fleming. He discovered Penicillin, the first natural antibiotic.
