Darwin noted similarities in species far removed from each other. S observations of finch beaks on the Galapagos Islands was one key piece of information helping him formulate his theory. Darwin did not realize these birds were finches to begin with.
Only after he brought specimens back to England did an ornithologist point out what his birds were. The adaptations in beaks was one of the things that helped him piece together his theory Other evidence existed in the numerous fossils Darwin accumulated. These fossils showed gradual changes in species over vast periods of time.
Birds and reptiles are diapsids, whereas all mammals (including humans) are synapsids. Darwin conjectured some fossil might exist to show a link between reptiles and birds, and that fossil was Archeopteryx. Since then we have found numerous other examples of transitions between species Yet more evidence is found in genetic similarities.
On the basis of their anatomy organisms can be grouped into tree like structures of nested hierarchies. These nested hierarchies are evidence of common ancestry. Any other classification system would constitute evidence against common ancestry, and hence against evolution.
However, genetic analysis produces identical overlapping tree structures. This is considered excellent evidence for the soundness of the foundational theory of biology.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
