For Wednesday 16 April Brian Thomas writes: “Fossil Plant Chromosomes Look Modern.”

An 180 million year-old royal fern fossil has been discovered in Sweden that is so stunningly preserved that it still shows the components of individual cells. The nucleus – and even the nucleolus – can be easily seen, and cells that appear to be in the process of division show their chromosomes. The paper, “Fossilized Nuclei and Chromosomes Reveal 180 Million Years of Genomic Stasis in Royal Ferns,” in Science, is unfortunately closed access, but phys.org has pictures. The preservation is good enough, in fact, that the researchers report that they’re basically the same as in living royal ferns. The “living fossil” creationist argument is probably well familiar to you, so the content of Thomas’ article shouldn’t be all that surprising. Continue reading

The Fact of Evolution

Dr John's Q&AFrom 1989 to 2006 the ICR ran a Frequently Asked Questions column – sometimes referred to as “Dr John’s Q&A” – in it’s Acts & Facts newsletter. For 2013 they appear to have revived the concept in the form of a new series of “Creation Q&A” articles. The first is by Nathaniel Jeanson, and his question is “Is Evolution an Observable Fact?

“Evolution is fact!” is one of the most popular evolutionary assertions made by evolutionists, ranging from those at the National Center for Science Education to those working for PBS. Proponents of Charles Darwin want you to believe that his hypothesis is being confirmed right before our eyes.

The NCSE page linked to does not actually make this claim, and neither does the PBS FAQ. Not a great start. Continue reading
