What is microevolution and how does it occur?
1 Answer
Microevolution isn't the same as macroevolution, and they both fall under what is generally accepted as evolution.
Explanation:
Microeveolution is small changes that change an organism's genetic code. These changes do not create new information, however, as many scientists would like to believe. They change genetic code only as much as the genetic code allows. Microevolution has been observed to happen as an animal's response to changes in its environment. Darwin's finches are often used to evidence macroevolution, even though it is actually microevolution that is occurring. According to microevolution, one of Darwin's finches can't become another animal or even another type of bird. They must change within the boundaries of the genetic code.
Macroevolution, on the other hand, has never been observed to happen, and is only a theory. Macroevolution is imagined to occur when an animal's genetic code changes so much that it becomes another animal entirely. This is obviously impossible and could never happen due to the limits of the genetic code. To summarize, evolution is composed of two parts: micro and macro evolution. Microevolution has been observed to occur in the world while macroevolution has never been confirmed or observed and is still just a theory.
