I have heard many ID/creationists claim that they are starting with the same evidence but are arriving at different conclusions. They also try to claim that what they are doing is scientific. Neither is true, as will be shown with multiple examples in this thread.
One of the biggest and most basic observations in biology is the nested hierarchy. In more modern parlance this is known as a phylogenetic signal. This observation dates back centuries and was first formalized by Linnaeus. Today, Linnaean taxonomy has mostly been discarded in favor of cladistics, but the central observation still holds: Species form groups within groups. The process of evolution will necessarily produce this pattern of shared and derived features among species where vertical inheritance is the dominant form of inheritance. Evolution can only produce a nested hierarchy under these conditions. This pattern of shared features is found in all of the complex eukaryotic species we see today, and it continues in the fossil record. We never see a fossil or living species that has a mixture of derived features from birds and mammals. This pattern is also mirrored in DNA, but I hope to get to that in subsequent posts.
ID/creationism can't explain why we see this pattern. I have yet to see any explanation from an ID/creationist where a nested hierarchy would be a necessary outcome of the process of intelligent design or separate creations. There is absolutely no reason why we should see this pattern of shared features if ID/creationism is true. The only explanation we have for this pattern is evolution.
If you want to know why scientists accept evolution and reject ID/creationism, the nested hierarchy is why. Until ID/creationists can explain why their proposed mechanisms would necessarily produce this pattern they will not gain traction in the sciences. ID/creationism isn't rejected because of its theological or philosophical implications. It is rejected because it can't explain one of the most basic observations in biology.
