Response to Jason Ezard

2022

Normally I would not write a written response to an article that I think makes false statements, but since I am directly mentioned in this one, I will take the time to respond. Since there are sections that are not directly aimed toward me or my beliefs, I will only look at the sections that are aimed toward me and my beliefs and then respond. The document I am responding to is authored by Jason Ezard, the document was created on Nov. 26, 2019. 2 However, recently, a section was added named, "Guzman Vs Jackson Roe Debate." a debate that occurred on Dec. 28, 2021. Many objections were raised, and I will respond here.

Response to Jason Ezard Jonathan Guzman1 2022, Independent Researcher, Texas N ormally I would not write a written response to an article that I think makes false statements, but since I am directly mentioned in this one, I will take the time to respond.

The document I am responding to is authored by Jason Ezard, the document was created on Nov. 26, 2019.2 However, recently, a section was added named, “Guzman Vs Jackson Roe Debate.” a debate that occurred on Dec. 28, 2021. Many objections were raised, and I will respond here. Feather morphotypes The author quotes a pop-science article from ScienceDaily. I have read a number of articles from the site and they seem to get their facts right more often than other pop-sci outlets, but the original paper3 is literally cited on the bottom of the page. But then he shows three pictures (fig. 1) of different feathers in different pieces of amber that has nothing to do with the article he cited. I digress. He takes issue with the fact that the authors of the paper claim that these structures are “proto-feathers” from a dinosaur. He shows pictures of what they could be such as mammal fur or feathers of a weird bird. Yet he does not name a specific taxon. It is pure imagination. While you could potentially use this thinking when talking about these specific examples, you cannot when talking about body fossils. Take, for example, Sinosauropteryx prima. Scanning Electron Microscopy (SEM) revealed fossilized melanosomes in the Sinosauropteryx specimen, IVPP V14202.4 Other studies reported β-keratin in a number of specimens.5-6 This is a problem for anyone who wants to suggest that the feathers in dinosaur fossils come from mammal fur (mammal fur does not contain β-keratin) or collagen fibers (collagen is not found in these specimens). The author also suggests that ostrich feathers look very similar to the specimen in figure 1C. The problem is that TMP 96.9.553 does not exhibit a rachis similar to any modern bird. These filaments are unique to extinct taxa and unlike anything we see today. Guzman v. Roe Debate I debated Jackson Roe on the origin of birds on Dec. 28, 2021.7 The author wrote a section about the debate saying, “There is no doubt that it’s [feathered dinosaurs] all wistful thinking on the Evolutionists part and ignorance on Jonathan Guzman's part”. Sometime between this comment and the time he spoke to our mutual peer he edited this statement to say, “There is no doubt that the evolutionists narrative on this is just wishful thinking, and on Jonathan Guzman's part, he did really well”. In this same section he stated, “This [CMI article] puts the idea of Dino feathers on the rocks. I read every word and they are right, there is no real evidence for Dino feathers this article puts the issue of dino feathers to bed, big time.” He edited this to say, “This article is good, I read every word and they could be right, there is no hard evidence for Dino feathers or against them. This article does not put the issue of dino feathers to bed”. I don’t quote these parts of the article to badmouth the author, in the contrary, I commend him for keeping an open mind ready to admit when he’s wrong. Although, it seems as though he doesn’t 100% agree with my position, at least he can see my reasoning and not be so closed minded. For the record, the author did contact me personally to apologize and say that I was right. Miscellaneous claims “Scientists admit, they never found birds in dinosaur layers before because they simply were not looking.” A source is not cited. “Ultra[-]complex [f]light feathers with dinosaurs, found on a regular basis, so often in fact that the evolutionists admit it…” This is not new, that’s why Archaeopteryx came as such a surprise 160 years ago. “So we have these weird structures that if they are pieces of feathers, sees the filaments off feathers, or some type of animal hair, it could be many other things.” But, as demonstrated in the first part, a specific taxon is never mentioned.
