The headline that prompted me to read this paper claimed that the study “shows how bacteria evolved powered-up propellers.” But the paper does not do this at all. All it shows is another example of a flagellar protein that bears homology to a non-flagellar protein.

The origin of spliceosomal introns represents a significant challenge to an evolutionary account of their origins. While the hypothesis that group II introns from bacterial endosymbionts gave rise to eukaryotic introns is the prevailing explanation, it faces a series of substantial obstacles.

There is a vast array of evidences, both internal and external, that reveal that the fourth gospel is composed by an individual who is extremely well informed, close up to the facts, and habitually scrupulous. This lays the foundation for multiple lines of argument for the truth of Christianity.

Here, I want to draw attention to a review article by Levine and Holland, published in 2018, on “the impact of mitotic errors on cell proliferation and tumorigenesis.” Noting that “mitosis is a delicate event that must be executed with high fidelity to ensure genomic stability,” the paper underscores the critical nature of various aspects of the eukaryotic cell cycle machinery.

McClellan’s tone may suggest confidence, but his failure to engage seriously with the subject leaves the impression of bluster rather than substance.

Any discussion of the evidence for the resurrection must first ascertain what the original apostolic witnesses claimed and whether those claims are best explained by the resurrection, or by some alternative hypothesis.

Recurring design logic across multiple unrelated systems is surprising in an evolutionary perspective, whereas on the hypothesis of design it is what might be reasonably predicted. Examples like this, therefore, suggest the existence of a master-architect behind biological systems — particularly when we find many different examples of design logic that are found recurrently throughout life.

By an unguided process of tinkering, it seems quite implausible that the genes would be appropriately arranged along the chromosome in a manner that corresponds to the timing of their expression. Not only must the necessary genes be organized into a hierarchical transcriptional cascade to ensure proper timing and coordination of assembly, but the specific order of the genes along their respective operons is also significant.

The book of Acts recounts various miracles performed by Paul and the other apostles, as well as the deacons Stephen and Philip. If it can be shown that these miracle reports substantially represent the testimony of these individuals, then this is an important aspect of the testimony that must be accounted for.

The process of chromosomal condensation is absolutely essential to successful mitotic cell division — that is to say, it is a part of a larger irreducibly complex system. Moreover, the highly condensed mitotic chromosome structures (with sister chromatids joined at the centromere) do not serve a purpose apart from in the context of mitosis. And yet, various components are themselves indispensable for effective chromosome condensation.
