Another thing about genesis mythology always intrigued me, regarding whether it might be “true”, is
I find it interesting that the Boa constrictor and the Python
both have under developed hind limbs called vestigial organs. The portion of
the limb that is visible on the surface of the scales appears to be talon like.
Mostly only one talon is present on each side. In some rare cases dual talons
are present on each side. The snakes have the ability to move these “claws”
around their pivot point whenever certain conditions motive them.

Here’s an interesting article about the Sonic Hedgehog gene.
https://www.nationalgeographic.com/news/2016/10/snakes-grow-legs-evolution/snakes-grow-legs-evolution/
"Sonic hedgehog is a gene that is necessary for limb
development, one of several genes named after the hedgehog-like spines that
grow from embryos when limb development begins.
An enhancer controls the activation of the Sonic hedgehog
gene, causing it to flicker on and off. In snakes, a mutation in the enhancer keeps
the gene from staying in the “on” position, allowing for limbs to grow.
“In lizards, Sonic hedgehog stays on and acts as the motor,
driving limb development all the way down into the fingers and the toes,”
explained Cohn.
In the recent study Cohn and Francesca Leal published in
Current Biology, researchers discovered Sonic hedgehog flickered to “on” at
certain stages of python development. That’s why pythons sometimes have small
claws protruding from their skin: They are beginning to develop limbs.
What that means is it’s possible for the pythons of today to
grow legs—and it doesn’t require an entire evolutionary cycle for them to do
so. They just need the right genetic mutation to help along the limbs they
already have."
The Boa and the Python already have the genes to grow legs but they are being inhibited for some unknown reason.
