- *V*– That’s common apologetic misinformation. Perhaps ask some experts: @EvolutionQA or @scientiapercept , @GodFreeWorld or @mrhawkes on twitter.
- *V*-“@KathyOrlinsky: If we had never found a single fossil, we would still know evolution was true thanks to the genetic evidence, that’s how strong it is.
1. Ubiquitous genes: Not only do all organisms on Earth use the exact same DNA codes, but also, in many cases, the same genes. You can replace the cytochrome C gene in yeast with the cytochrome C gene from humans, insects or birds and the yeast cells don’t know the difference.
2. General patterns: Humans are more genetically similar to chimps than to to dogs, more similar to dogs than to fish, more similar to fish than to lobsters, etc. If each species were created independently, we would not see this pattern. On the other hand, the pattern is perfectly explained by common descent.
3. Specific changes:
a. We see the same exact mutations in the same exact places in the same genes of both humans and chimps. In many cases, the mutations destroy the functioning of that gene. There would be no reason to purposefully mutate the genes in this manner, and the odds of having the same exact nucleotide altered in the same way in two species would be astronomical. The best explanation for this observation is that the mutation occurred only once in the common ancestor of chimps and humans. All of that ancestor’s descendants carry the mutation.
b. Sometimes viruses get permanently fused into an animal’s genome. The descendants of this animal will all have the exact same viral sequence in the exact same place in their genomes. The same viral sequences in the same places can be found in both chimps and humans despite the fact that these viral insertion events are completely random.
