This is the least important to me because although it is a key fact, it is pretty obvious considering the changes of organisms around us.

Although his observations are very important to science, knowledge of the subject has advanced and people have critiqued his observations.  This is also just a minor part of my knowledge about evolution.

This is important because it is evidence of evolution and common descent.  The similar structures in different organisms is an outstanding discovery.

This is significant because without descent with modification species would vary in little amounts. This was an important observation for all species.]]> 2017-05-17 19:54:54 UTC https://padlet.com/macbarnard/nixusyzsvd7i/wish/172434080 macbarnard https://padlet.com/macbarnard/nixusyzsvd7i/wish/172434122 Natural selection plays a huge role in evolution.  Natural selection is a process in which favorable variations for a particular environment survive, reproduce, and pass these variations of to following generations. 

This is significant to me because if you know the process of natural selection that you have a better understanding of how organisms evolve.
