selection. In 1859 he published book where Darwin explained his theory, it is called On the Origin of Species, the main ideas were that all organisms compete for resources, and unsuccessful species ,who unable to compete , will become extinct, successful species will inherited. One more theory of evolution took place in our history. To take a look on primates we wouldn’t believe that they are our ancestors, but after discovering first fossils , paleontologists showed the timeline of evolution where we came after big amount of developed and adapted primates and hominids. Henc e our ancestor was early primate , not ape, how many of us thought. There are many evidences of our affinity such as genetics, first fossils records and evidences from molecular biology.The sequencing of both the human and chimpanzee genome,their DNA sequences range between 95% and 99%.

Theories about human’s ancestors came not just from mammals, furthermore from marine animals, like fish. This kind of hypothesis called “Aquatic ape hypothesis”, was proposed by German naturalist, Alister Hardy in 1929. It gives us thought of difference between Homo Sapiens and primates in our skin formation, protruding breasts of females , protruding nose. The main point which Hardy tried to approved that all these factors were caused because of life in water . The primate which lived in water was called Hydropithecus , supporters of the aquatic theory believe that the traditional theory of modern human origins are three basic evolutionary phase that are not justified within the Savanna theory, however these three steps of humans evolution can be also explained by basis on Aquatic ape hypothesis. Unsuccessfully this theory didn’t get wide support in academic world, but many of people were impressed by logical explanations , which theory supporters gave : the way bipedalism could be developed in water is much logical, because of lack of necessity of using just legs ,and that the hair on our skin have the same direction as it becomes with water resistance. Before just one theory could logically explain us our body structure until this one took interest of many people, but wasn’t considered by scientist as important one.

The last theory , which also took places in many minds, is about that the Earth is not humankind’s home. Dr Ellis Silver wrote a book where he pointed to a number of physiological features to make his case for why humans did not evolve on Earth as all other nature life. These features are bad backs and suffer with sun temperature. He also says that it is strange that babies’ heads are so large and make it difficult for women to give birth, which can result in fatalities of the mother and infant, when any other species don’t have such problem. Our imunitetis are weak and head problems, all cause because of wrong biological clock, as we should have 25 hours per day , how claims Dr. Silver. Our back hurt because of higher gravitation that on our real “home” planet and that place were far away from sun, which gave us better condition to live and be safe every day. Many people started to feel that the Earth is not their planet, but if it is true, then the question how did humans transport to the Earth ,takes place. There can be few hypothesis such as moved on meteor or external forces like aliens brought us here. However to such statement there are not evidences, so it can not take scientific support.

To sum up,any of theories still don’t have final proof if one of them true
