Key Point Of Evolution

Evolution is the theory that over time a species will slowly develop new characteristics and eventually become an entirely new species. Based off of fossils that have been found, studied, and tested, scientists have been able to create what they call a fossil record. In the fossil record there is evidence of minor changes in creatures and those changes taking millions of years, overtime these changes amounted to a point where the creatures were completely different, this proves that evolution is true. The changes started with a creature called a chordate which was essentially a very primitive fish. Over time some of these fish located to shallow areas of water, to adapt to the shallow water the fish developed very primitive versions of arms,

Early mammals were different from early reptiles in that they had developed a bigger brain and they used keratin not only for claws but also hair. Eventually certain mammals developed into early primates and developed the ability to climb branches. One defining characteristic of early primates that set them apart from just about every other creature is their eyes eventually moved from the sides of the face to being in the front of the face, this development was another key point in evolution. Eventually primates split into two groups, the first one being old world monkeys and the other being Great Apes which are also called Hominidae. Some key characteristics of great apes that set them apart from old world monkeys is that they lost their tails, began to walk on two feet, and gained flexible wrists. The development of flexible wrists and becoming bipedal was another key point in evolution, this is because being bipedal allowed for greater movement and flexible wrists allowed weapons and tools to be used once they were
