Carbon dating supports evolution
If common descent occurred, then the organisms found in the fossil record should generally conform to the phylogenetic tree — the nodes on the tree at which a split occurs represent common ancestors of the organisms on the new branches of the tree.
We would predict that we could find organisms in the fossil record showing characteristics that are intermediate in nature between the different organisms that evolved from it and from the organisms from which it evolved.
In fact, the fossil record does show the same order of development.
Inferential evidence isn't as strong as direct evidence, but it's treated as sufficient in most cases when enough evidence exists and especially when there are no reasonable alternatives.For example, when examining the anatomy and biochemistry of living species, it appears that the general order of development for the major types of vertebrate animals was fish - mammals.If current species developed as a result of common descent then the fossil record should show the same order of development.If you look at the fossil record, you find a succession of organisms that suggest a history of incremental development from one species to another.You see very simple organisms at first and then new, more complex organisms appearing over time.
