In 1846 Vienna, childbed fever ran rampant causing death among many pregnant patients. Consequently, Dr. Ignaz Semmelweis began an experiment where his doctors washed their hands resulting in a decrease of patient death thus leading to Germ Theory.
Through his calculated cross breeding studies of garden peas, Mendel discovered a pattern of dominant and recessive traits which lead to groundbreaking advances in the field of genetics.
With his construction of his own microscope, Antonie van Leeuwenhoek discovered microorganisms, namely the protozoa, which are single celled pond organisms. Because of his work, he is considered the first microbiologist.
Alexander Fleming's discovery of penicillin lead to the successful extraction and testing of penicillin on mice injected with streptococci. These tests gave birth to the first antibiotic which became a life saving cure for a variety of diseases.

In a clip from Assignment Discovery on Discovery Channel scientists believe that new species come from small mutations over long periods of time, where organisms have to adapt to their environment.
In this clip from Assignment Discovery on Discovery Channel, Darwin studied the selective breeding of animals on farms and compared this artificial selection to his theory of natural selection.
Humans have no automatic right to life on earth, and in this clip from Assignment Discovery on Discovery Channel, we realize that we have to fit in to this way of evolution and stop thinking about the short term.
Mutation is a random change in genes to adapt to the individuals environment. This clip from Assignment Discovery on Discovery Channel teaches us more.
Instead of Survival of the fittest, Darwin calls it the Survival of the best adapted. In this clip from Assignment Discovery on Discovery Channel Darwin's believes are compared to that of Hitler and other powerful people through history, and the ...
Mutations in Bacteria supports the ideas of Darwin. These days the Bacteria mutate very quickly and become resistant to the drugs we have available. Assignment Discovery on Discovery Channel investigates further.
