A tiny piece of 15 base pairs is 60 or 70% similar with egg layers and in the human genome
so we are related to an egg layer so the claim goes
But really.. 60 to 70% is not so high and the so called sequence inside a larger section of DNA for brain so the case is not made

The main piece of evidence for the vtg pseudogene is the presence of a 150-base human DNA sequence that shares a low level of similarity (62%) to a tiny portion of the chicken vitellogenin (vtg1) gene.8 However, the chicken vtg1 gene is actually quite large at 42,637 bases long, so a 150-base fragment of 62% similarity represents less than 0.4% of the original gene if the evolutionary story were true! But this miniscule amount of questionable data isn’t the only problem for the evolutionary egg-laying fable.

As an enhancer element, the 150-base alleged vtg sequence contains a variety of highly specialized sequences that enable the binding of specific protein machinery that controls the activity and function of the GAM gene.8 These specialized sequences are also associated with a wide variety of epigenetic marks—chemical modifications in the DNA. The specific types of biochemical data associated with these marks also tells us that this DNA feature is not only active but important to the overall three-dimensional structure and function of the GAM gene in a process called long-range chromatin interaction.8,9
Upon investigation, we see that this 150-base sequence is not an ancient egg-laying “fossil” in the human genome. It’s a functional enhancer element in a GAM gene expressed in brain tissues. Once again, when we examine the genetic data more closely, the evolutionary scoreboard shows nothing but a big zero—a “goose egg,” as the saying goes.

appears a really bad argument
