No Sign of Evolution for Neurons

Neurologists confidently put their pinky fingers to the corners of their mouths when announcing that humans have one hundred billion neurons. Those nerves obtain information from the outside world so the brain can sort it out and direct muscles. They communicate with other cells via synapses. Ever strike a match and hold it too long, then yelp and throw it away when you got burned? Neurons are involved. Also, it may come as a shock to learn that there is an electrical component to neurons.

Neurons — nerve cells — number 100 billion in humans. Evolutionists have no explanation for their evolution. That is because they did not evolve.

Believers in baryon-to-brain surgeon evolution presuppose everything evolved from simple to complex. It was thought that neurons evolved from cells called choanocytes because of superficial similarities between them and nerve cells. Interestingly, although there has been a marked increase of late in fossilized soft tissue, there is not enough to attempt to trace the alleged evolution of neurons. They conveniently overlook living fossils — creatures unchanged over alleged millions of years — to make comparisons.

If secularists would take off the blinders and actually look instead of following the narrative, they might realize that there is no evidence for evolution because evolution did not happen. What they are examining is the brilliance of the Master Engineer.
The chasm that exists between nerve cells and their proposed evolutionary precursor cells has never been bridged by evidence, nor even by theoretical just-so stories. The problem of the evolutionary origin of the neuron is widely acknowledged by many evolutionists. The reasons why this gap exists, and will never be filled, are documented here. The first neuron must have had all of its basic parts assembled and integrated properly in order to function as a neuron.
