God makes DNA replication suspiciously evolutionary, tricks me again

God is so tricky. New research reveals that the structure of a DNA replication molecule is similar across all three domains of life:

In two papers that will be concurrently published in the August edition of the journal Nature Structural and Molecular Biology (now available on-line), the researchers report the identification of a helical substructure within a superfamily of proteins, called AAA+, as the molecular "initiator" of DNA replication in a bacteria, Escherichia coli (E. coli), and in a eukaryote, Drosophila melanogaster, the fruit fly. Taken with earlier research that identified AAA+ proteins at the heart of the DNA replication initiator in archaea organisms, these new findings indicate that DNA replication is an ancient event that evolved millions of years ago, prior to when Archae, Bacteria and Eukarya split into separate domains of life.

...

Biochemist and structural biologist James Berger, a participant in both studies added, "Our findings of evolutionary kinship between the DNA initiators in all three domains make sense because, to paraphrase Francois Jacob, the one thing a cell wants to do is to become two cells. A cell can't do this if it doesn't replicate its DNA in the right place, at the right time, and in the right manner, while simultaneously avoiding over-replication." (Emphasis mine.)

See you would think that he would like me to conclude that the similarities of between three domains of life are because they evolved from a common origin, but actually he planned it that way just to play with me. This joke has been like 3 billion years in the making.

God...you so crazy!
