Sixth day of trip

      So yesterday I landed in Japan, everywhere I go I see and read interesting articles. Here is another one that sparked my interests about mutations:

Positive, Negative and Neutral Mutations

      Positive mutations happen when there is a mutation in one's DNA and they benefit from having it. For example, some people have a mutation that makes them resistant o the HIV virus, or a bear living in the artic getting white fur-it helps them blend ino their environments.

      Negative mutations are when there is a different type of mutation in the DNA or gene that has bad side affects. For example you can get diseases, or be deathly allergic to things, those are just a few examples. 

      Neutral mutations take place when it has almost no effect on how the one with the mutation survives. For example, being born with perfect eyesight, it doesn't decrease or increase their abity to survive.
