It’s not just gaps in knowledge. Its genes not following an expected ancestral pattern. There are more then a few examples of this.
I’m very well aware that the data does not fit a tree. This is exactly what we expect in common descent, for data to only imperfectly fit a tree. This is not evidence against common descent. Rather it is evidence against a cartoon version of common descent. I reject the cartoon, and see no real challenge in that data to which you refer.
Why would you expect genes to not follow an ancestral pattern?

Read the exchange with Ewert, I explain it there. I’ve explained it several times before: Winston Ewert: The Dependency Graph of Life.
Do you agree that the DNA sequence differences between species explains the anatomical differences between them?
Do you agree that mutations change DNA sequences?
I am describing what is fact, and how those facts support the theory.
How is gene deletion contradictory evidence? We know that gene deletion can and does happen, so why shouldn’t it be included in the theory?
The nested hierarchy is both similarities and differences.

Dear @Kathryn_Applegate ,
I see that Biologos is now selling Christian Textbooks. As a Southern Baptist Christian, I ask that you keep up this ground mission. I would even like to read some of your grand text. It has been a pleasure to write to you. May God the Father, Son, and Holy Spirit bless you. I should have called you Dr. Applegate. My apologies.
Hello Patrick,
I like your idea as I understand it. Before I went to Divinity School, I studied biblical courses in a public university. They were quite interesting.
I God created by TE/EC, then I must accept it as creationism.
Based on the quantity and pattern. Its more then a few deleted genes in a couple of cases its a trend of genes not following ancestral patterns
You’re explaining the nested hierarchy. Common descents mechanism is what is important.
They follow ancestral patterns just fine. I don’t know why you think they don’t. We would expect gene deletions to result in lineages lacking genes that other lineages have if evolution is true.
The prediction that evolution makes is about the pattern of similarities and differences in genes that are shared.
Mutation (including deletion mutations), neutral drift, and selection are also important mechanisms in producing nested hierarchies.
How many deletions would you expect and why? Whats the model you are proposing?
There is no expectation of how many genes will be deleted in any given lineage. It is largely due to the specific environment that the species is in. For example, gene deletion of odor receptors in cetacean lineages is quite high because there is no longer any selective pressures to keep them in place.
