Evolution and Planet Earth essays For some unknown reason, the belief that human beings came from monkeys has been a translation of the theory of evolution. This is one of the biggest misconceptions in the many myths regarding evolution. Evolution is a process that explains why life on Earth looks the way it does today. It provides a theoretical look at the changes that life, as we know it has undergone. Over time, plants and animals have changed and still change to adapt to their varying environments. These adaptations are a result of the catalyst of evolution known as natural selection. For any species, only the strongest and most well-adapted individuals will survive. This alone is why humans appear as they do today. Human evolution has nothing to do with the descent of humans from monkeys. Evolution has been widely discussed and heatedly argued. Although there are arguments against it, evolution has taken a strong foothold in the scientific community. Evolution has shaped and is still shaping life on Earth. However, a problem with looking at evolution is the amount of time it takes for this process to occur. Because of this, we must look at the evidence that has been found over long periods. One example is variation and change. It is evident to the naked eye that except for identical twins, which are easily explained not all living things (plants, animals, and mammals) are exactly alike. Life is constantly varying and changing to take on a form superior to its ancestors. This accounts for cattle being born with no horns, sheep with short legs, and in 1849, and a grapevine producing a new species of grapes now known as Concord. One powerful example is a new grass, formed from two species crossing, growing so quickly and efficiently it killed off its parents. Another example that favors evolution is the remains left behind in fossils. Although it is true not all living things become fossils upon death, variation and change can be viewed in fossil remains.
