Natural Selection Blog

Natural Selection is the process where organisms get close with their environment where they are comfortable with it.  Natural selection takes the necessary (good) mutations, genotypes, and phenotypes.
For example, the beak of birds change over time because in different environments, their beaks are needed in different applications.


Exaptation is where an organism has a trait that wasn't there originally.
For example, dinosaurs did not originally have wings, but over time their ancestors, birds, developed wings through exaptation.
