Ken Ham just claimed dinosaur bones contain unfossilized red blood cells. I break down what was actually found, and why the difference matters.
This is episode 12 of the Hemoglobin Challenge, where I check whether young-earth creationists are using soft tissue preservation terminology correctly. This time the challenger is Ken Ham himself, responding to an Answers in Genesis post claiming that Mary Schweitzer's famous 2005 T-Rex discovery included red blood cells, blood vessels, and collagen fibers. I walk through what was really recovered (chemically modified heme molecules and cell-shaped structures, not intact cells), explain why hemoglobin cannot survive tens of millions of years but its degraded byproducts can, and offer Ken Ham a corrected, accurate version of his own post.
Chapters
0:00 Introduction to episode 12
1:34 Ken Ham's post on X and Facebook
3:10 Context: Andrew Snelling's series and Fazale Rana's book
5:05 What Ken Ham wants his audience to believe
7:14 Cell structures versus actual red blood cells
9:14 Why red blood cells are so fragile
11:19 Blood vessels and collagen fibers examined
16:04 The heme molecule and why it can persist
21:06 A corrected version of Ken Ham's claim
22:00 The thousand dollar bill analogy
