How theory of evolution is useful: predicting food allergies!

Google: “A clade is a grouping that includes a common ancestor and all the descendants (living and extinct) of that ancestor.” So Clades presuppose evolution. I define Similarity more broadly to include all info available from morphology to DNA. I think you mean to narrowly include only morphology.

This is not what I am referring to. I am referring, instead, to a specific pattern in sequences. In this case, it has nothing to do with morphology. Of course, morphology falls in nested clades too, but that is a different conversation. We are talking about sequences here.

Just read the papers I linked to and the original post. It is very clear.

Phylogeny vs Similarity and Function

At a genetic level we see a great deal of similarity between organisms. This similarity is a fundamental feature of life, that has to be explained by any theory. Evolution explains that this similarity as largely caused by shared history, by way of common descent. We see function often aligning in sensible ways on phylogenetic trees of sequences and organisms. Of course, this is not perfect, because we also know that life changes over time. As the YEC Walter ReMine accurately points out in The …

If so, what are the alternative hypotheses tested? Please do not include random distribution here.

As I have explained several times, the alternative hypothesis tested is that similarity predicts function better than phylogeny. This exactly your hypothesis.
