Evolutionary change The myth from section A I want to dispel is the third one, evolutionary change is always good and all traits are adaptive. Related to the evolution of human being, I agree that evolutionary change is good and all traits are adaptive. There were 15 to 20 different species of early human existed during the past 100,000 years, according to the human evolution, in the article “Introduction to human evolution”, it is said “Other important human characteristics -- such as a large and complex brain, the ability to make and use tools, and the capacity for language -- developed more recently”. (Smithsonian’s National Museum of Natural History) So, these different kinds of human …show more content…

For the first question, why are there still apes and monkeys, I think it is decided by the environment. The path to evolution is not designed by nature. It’s hard to say how the species will evolve in the future. Evolution depends on the environment species need to adapt. Changes in the living environment will make them evolve into completely different species. To monkeys and apes, the environment they lived is suitable for them. So they don’t need to evolve into human to adapt their environment. Without specific environmental conditions, monkeys and apes cannot evolve into human.
Secondly, to the missing link, the species between human and apes missed because of evolution. According to Darwin’s natural selection, if the transitional species didn’t evolve during time, they would extinct. For example, early human, they also evolved from apes and share similarities with modern people. They moved out from Africa and they needed to adapt to new environment. Some of them had good genes to adapt and they left the genes to later generations. However, some didn’t and they extinct, because they cannot adapt to living environment. So, that’s why there is no transitional species at same time living with human and apes. They need to evolve or they will extinct. That’s the reason why there is the missing
