Basically, random mutation and natural selection. With a little genetic drift and gene flow thrown into the mix. Evolution, the change in allele frequency over time in a population of organisms.

Human thought does not travel at a physical speed like light or sound. It is a neurological process that occurs within the brain at a much slower pace. Communication can travel at the speed of light through technologies like fiber optics, but human thought is a complex internal process that does not have a measurable speed in terms of distance covered per second.

Codon combinations can be thought of as one word in the genetic message. Codons are the three-letter sequences of mRNA that correspond to a specific amino acid or a start or stop signal in protein synthesis. Multiple codons are strung together to code for the sequence of amino acids that make up a protein.
1.5 to 2 billion years ago. when the eukaryote cell is originated, so did mitosis. So you would see at the 23rd minute of the video below.
