Micro evolution is a change that occur in one specie. There is 5 types of micro-evolution and you can even use your fingers to help you remember the 5 types of micro-evolution. The 5 types of micro-evolutions are natural selections, gene drift, mutation, non random mating and gene flow. To help you remember the 5 types you can use your five fingers to help you. I will explain to you how the five fingers will help you remember.
Natural selection happens to an environment with climate change or just a change within the species. The organism of that species who has the "best fit" will have the advantage on surviving and reproducing a lot more than those who aren't a "best fit." If you are wondering what best fit is, it is the organism who is capable on surviving and has advantages that allow them to find resources better and reproduce. If a climate changed had happened and the organism that was able to survive to the harsh environment will get the chance to give off their good genes to further generations. To help you remember this you can use your thumb. Your thumb gives people the thumbs up if they did a good job and a thumbs down if they aren't. Just like that your thumb can give the thumbs up if they are doing a good job on adapting and reproducing and the thumbs down to those who aren't doing so well adapting to the environment.
Gene drift is when a random event happens to that specie. It can be the colour of the organisms or something that will actually help them adapt better than the original specie. For example you have a bed of really pretty white roses and something happened and you got a red rose out of all the white roses. If the red rose adapts and reproduces well in the bed of white roses you can end up with multiple red roses, but if the red rose doesn't really adapt very well the red rose won't be able to reproduce. In the end the red rose will die out leaving the white roses the same as before. These random outcomes can pass down their random characteristics to future generation resulting a change within an environment. Using the five finger method you can use your pointer finger to remember Gene drift. When you point at a squirrel you are pointing at a direction. Where ever you point you are changing that direction, just like that in gene drift you can observe the movements of the changing environment. Just like when you point at something everyone will be looking that way. If a random outcomes happen the unique outcome will be most noticeable like the red rose in a bed of white roses.
Mutation happens when a sequence of the DNA is changed resulting in something different. This change in the DNA can be good, bad or even neutral. If the change was neutral or good this change can be passed to future generations. If the mutation was successful and succeeded on passing their good DNA that helped them survive to their future generation which will change the species and change the gene pool as well. Using the 5 finger method you can use your middle finger. The "M" in middle finger can help with mutations since they both start with the letter M. Also if the mutation is bad and caused then difficulties on surviving you can give that mutation the middle finger to show they did a bad job on helping the organism.
Non-random mating is mating that is intended and not random. There are 3 types of non random mating and those 3 types are harems, assortative mating and sexual selection. Harem is a male with a lot of wifes. For example a male with a lot of females. Assortative mating is mating and choosing someone that looks like themselves
fun facts: The five finger rule actually helps you memorize micro evolution a lot easier!!!!
