The Story of :Genie the Feral Child

Every child deserves to live a wonderful life,that includes: good & lovely family,medical & hygienic care,freedom and of course any type of education and general knowledge. Unfortunately there are some cases where these types of having a wonderful life are neglected. Like for example the case of Genie. 
A story of a small girl that was abused by her father for about 12 years. She was living in a small room with only a bed and a toilet. The most of the time she was spotted to a chair,so she was not even able to move. Her father was abusing her every time she tried to "say"something, so not that she couldn't move,had problems with seeing because of not being used to sunlight, she was also not able to speak. 
When she  was 13, a team of psychologists and language experts began the process of rehabilitating Genie.She was living with few foster parents but no one was taking the amount care of her she needed. Finally a famous psychologist,together with his wife took her and lived with her for about 4 years. Genies "teacher" was helping her to know the basic things, like recognizing colors or holding things. Genie was very shy,silent,incontinent and unable to chew. The only thing she was able to do was to recognize her own name and to say "sorry".  She made a huge progress right in the beginning of recovering and started to change and live from new on. The psychologists and doctors discovered this case for a very long time and after years of researching they asked themselves if Genie was not retarded from the day she was born.

The Theory of Evolution

Darwin's theory of evolution started with the natural selection. When he thought that a mammal can turn into a whale. He used black bears as an example,becase they were able to swimt and catch food in the water. Few years later,scientists figured out that his theory was not wrong,he just choosed the wrong animal. He should choose instead of bears hippos or cows to make this experiment happen. 
His theory of evolution by natural selection is supported by lot of sources and that's why it is one of the best theories in the world. Natural selection is a process by which organisms change over time in physical or behavioral traits. These are very often changes that help organism to better adapt in its environment. 
 The physical and behavioral changes that make natural selection possible happen are based on the level of DNA and, ofcourse, genes. These changes are called mutations. Natural selection quides the evolutionary process by adding the good mutations and deleting the bad ones.  

Charles Darwin


He was an English naturalist and geologist,known for his theory of evolution. He was borned on February 12, 1809 and died 19. of April 1882.
His main point of his theory of evolution was that all living things are related and descendet from a common ancestor. This means that even though are genes are changed every generation,we do have lot of things common with our predecessors.
