I guess I would need to see an analysis of whether there's been any change in human allele frequencies. I suspect there hasn't.
But to your example, one issue with the farmed fish is that they now constitute a closed gene pool - we can easily explain their decreased fitness with the likely rise of harmful alleles.
With the explosion of population, I don't see much relationship between the salmon and humans.
- roceasta 9y agoThanks. I should read up a bit. Can you link to any decent info or discussion about allele frequencies?
- evolve2017 9y agoIncidentally, I'll be starting a PhD in a human genetics laboratory, but I don't have a lot of experience with this kind of literature. This seems like a reasonably accessible (college-biology level) discussion of what evolution would look like in the human gene pool: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2933187/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2933187/ ---- EDIT: I suspect you'll need a university library to access this, but Dr. Pardis Sabeti is well known in this area and also an amazing person - she played a big role in the molecular biology work that underlay the US response to the Ebola crisis. She wrote a review that explains the tools we currently have to ascertain human evolution: https://www.ncbi.nlm.nih.gov/pubmed/16778047 https://www.ncbi.nlm.nih.gov/pubmed/16778047
