2. This is a short write-up about biological evolution. Answer: After the gradual change of simple organisms, the process of creation of different organisms is called biological evolution.

&nbsp;&nbsp; &nbsp;Life behind the origin is a combination of various processes. At the beginning of creation, some very simple organisms were emerging in different forms to adapt to the changing conditions in different geographical periods. Slowly but surely the laws of nature have been unfolding since the dawn of creation. Lemarck, Darwin, Wiseman, de Vritch etc., these advanced theories are called biological distribution theory alone.&nbsp;

3. A detailed description of human evolution. Answer: The history of human evolution is a long history. After the creation of the earth, there was no existence of the human species on earth for many years. Mammals emerged during the Mechzoic period following geological directions. About 36-42 million years ago, this sub-branch or class of mammals called primates was created. Chimpanzees like gorillas, chimpanzees, gibbons, chimpanzees, and humans fall under this primate category. About 24 million years ago, these primates evolved into the subclass hominids. Kharanaziya Bandar, Manuh belongs to this subclass of hominids. Hominids evolved into another species called hominids. The hominids belong to the tribe Hminiidae. The main differences between hominids and hominids were the shape of the brain and the shape of the skull. Human brains were relatively large, allowing them to search for loads on top of two loads. The front of Hminidbilak's body was covered with two loaded weights, and as a result, the two hands were able to put on their hands. Hminidbila was able to perform various ahila tasks by hand. Hminidbilakkapun has some maths shared. Two notable ones in the year are Ashtral' Pithikach and Ham'. About 5.6 Niyut years ago, the Ashta'pithikach people were born. Ashtal'pithikachak can be called as the oldest form of human hichapa. The word ashtal'pithikach has two origins. The Shudra meaning of 'Astral' is 'southern fall' and Pithekachar means 'noseless monkey' i.e. the Latin word astral'pithekachar means - 'noseless monkey of the southern fall'. The evolution of fossils ended in the Miaochen period, a subdivision of the Tertiary period within the Chinozoic era. The brains of these creatures were relatively narrow and had tooth-shaped fangs. Most of the time was spent on tree branching in Ashtral'pithikas, as a result of which he had to use almost four sticks. However, due to the frontal part of his body being long, he could find a standing position due to the heavy bones and joints of the moving horses. The modern era has been referred to as the 'Human Age' in various scholars.
