Ben Levi,
1.) There are multiple strings of evidence that point to common descent.
2.) It is not the “skeletal similarities” that are used in of themselves. There is a clear nested hierarchy that is not predicted by special creation.
3.) When Scientists question if the fossil record supports “Darwinian evolution” they are not questioning the fossil record’s support of common descent. They don’t question that because the fossil record does support common descent. There ARE transitional fossils found in the strata where they would be if common descent is true. The discussions among scientists are what theory as to exactly what mechanisms caused it and causes it fit best with the amount of transitional fossils found.
Like was pointed out above this is a distinction that most people who have not actually studied evolution fail to grasp and it applies to the vast vast majority of quotes thrown around claiming to show that scientists do not believe in evolution.
