Evolution - What Darwin Never Knew

Darwin propose natural selection as the means of evolution, but he did not know the actual mechanism of how it work.

This video "Evolution - What Darwin Never Knew" attempt to fill in what Darwin did not know, that genes is the actual mechanism of natural selection.

The basic conclusion is that small changes in genes can have profound effect. For example, humans and chimpanzee genes are 99% identical. Thanks to these small changes, it is always possible that fins can be evolved into limbs because the same genes contain all the functions for the making of fins and limbs - Hox genes.

The example given in the video of the evolution of tiktaalik evolved limbs to escape predators in the ocean is ridiculous. Not only would tiktaalik need limbs, it would need lungs. How does the tiktaalik evolve limbs and lungs mindlessly and without planning? To me, all these discovery do not prove evolution. It proved that there is a God who use a basic design to design all vertebrates.

Children are imaginative because they do not let facts get into the way of their imagination.
Likewise evolution flourish when we do not know the facts of the actual mechanism of change.
