Decoding Epigenetic Hox Gene Regulation in Snakes - Theological Implications
The intricate tapestry of animal development weaves intricate patterns, sculpting diverse body forms from a single set of genes. Hox genes, master regulators of body patterning, play a pivotal role in this orchestration. But how are these powerful genes themselves controlled? Epigenetics, the layer of instructions atop the DNA, holds the key, influencing Hox gene expression through a fascinating dance of chemical modifications and protein partnerships. Snake development offers a captivating illustration of Hox gene regulation. These limbless reptiles, despite lacking external limbs, retain limb-associated Hox genes in their genomes. Even more intriguing, some Hox enhancers, regulatory DNA sequences that switch genes on, exhibit shared activity in both the phallus, a modified limb used for reproduction, and the remnants of internal limbs buried within their bodies. In neo darwinism why would limbs evolve only to devolve? Neo darwinism does not go backward. Mutations are...
