Muller’s ratchet states that in asexual populations, deleterious mutations accumulate in that population irreversibly (like a ratchet). Since populations in early evolutionary life would have been asexual, Muller’s ratchet presents a… read more →
Certain portions of the genome are more likely to mutate than others; thus, the randomness is not evenly distributed. This makes it much more difficult for evolution because for a… read more →
Evolution requires mutations to produce brand new information. Oddly, however, we have never observed a single mutation that has increased the information of an organisms DNA. This presents a very… read more →
If the human population is to keep from degrading genetically over time, there can be absolutely no more than one deleterious mutation per person per generation, and realistically no more than… read more →
For evolution to work, natural selection has to recognize and eliminate bad mutations, while recognizing and promoting good mutations. However, most mutations are much to small to make any detectable… read more →
Harmful mutations outnumber beneficial mutations one million to one. This fact, together with the fact that most mutations are invisible to natural selection, provides strong evidence that we are degrading,… read more →
Mutations build up in us over our lifetime, eventually causing us to get old and die (if something else doesn’t kill us first). This demonstrates that most mutations are harmful,… read more →
