In response to this omission, three days later (28 March 05) Answers in Genesis published another article addressing the Ostrich comparisons (see below for link). The new author (Dr. David Menton) says this is not the first time that soft tissue has been found, and he provides a link back to the already disproven AiG report on T-rex blood cells. Dr. Menton appears to bring up some valid arguments about Dr. Schweitzer's article, mainly that the comparisons of the structures of the T-Rex and Ostrich would be common to most amphibians, reptiles, birds, or mammals. The assumption made by Dr. Menton is that there is an unstated conclusion that dinosaurs evolved into birds, and thus he is attempting to discredit the similarities between the ostrich and T-Rex. However, Dr. Schweitzer does not mention evolution at all in her article. She is merely showing similar features between two organisms, which were obtained in similar procedures when applied to two different creatures.
Dr. Schweitzer may be using the comparison for proof of dinosaur to bird evolution, but it is more likely that she is merely showing a modern example, for the sake of clarity of understanding. Dr. Menton admits that he sees an unstated conclusion that "this similarity in microscopic structure proves that dinosaurs and birds are closely related through evolution." Nowhere does Dr. Schweitzer make this claim.
In the end, the layman reading these articles must decide which scientist to believe. Since Dr. Schweitzer has no religious motivations for proving a young or old earth, hers is the more objective, or fair and balanced approach, and in this case is a more reliable scientific source than Dr. Menton (see www.answersincreation.org/scientist.htm).
