I say this because I believe speciation is driven by genetic mutations and not natural selection.
I believe you are categorically wrong here ... we're only concerned with genetic mutations that effect an individual's ability to fulfill its reproductive capacity ... more babies surviving to adulthood ... nothing else seems to matter ... consider a mutation that allows an individual to grow 50% larger, such that it is not preyed upon but kills any and all potential mates during the mating process, that mutation is dead-in-the-water as it will not be passed on to future generations ...
Charles Darwin made some mistakes ... the Modern Synthesis very strictly defines "natural selection" and "survival of the fittest" in terms of reproduction ... the more adult offspring, the more a positive inherited trait is passed on ... k > 0.5 ...
Instead of looking at one species or another, I am taking a broader view. I am trying to explain why stasis and lack of transitional fossils are the norm. The best explanation I can come up with that fits the data is there are no transitions because speciation happens fast. And for that to be the case, it must be wide spread genetic mutations driving the process. Given that recent studies suggest that the food we eat can modify our genes and potentially our children’s, I don't think the possibility that widespread genetic mutations driving speciation should necessarily be discarded just because it goes against what Darwin believed.
Do you have an example of the fossil record showing a "quick" change to a species (which species "fits the data")? ... I'm not discarding widespread mutations driving speciation in
all cases, but we need to be very careful how we're defining speciation ... not all outward physical changes are associated with the genetic material, human skin color is a good example where all of us have all the genetics needed to be Congolese Black all the way to Laplander White ...
But let's use the less controversial example of the English Birch Moth ... in the year 1800, these moths were almost all white with a few black spots, perfect to blend into Birch bark, and this is considered the dominate genetic form, very few moths were the recessive jet black, and these moths tended to be eaten by birds before they could reproduce ... the filthy English started burning coal and vented the soot to the atmosphere, covering all the Birch trees making them jet black ... by 1900, the spotted white moths were all but gone, having been eaten by birds, only the jet black types remained as they were the ones to blend in with the Birch bark ... these are the
same species in every way, just one shows dominate colors and the other shows recessive colors ... both types freely interbreed and thus form a single taxon ... England has cleaned up their act and the moths are reverting back to the spotted white forms again ...
Just a note, Charles Darwin self-published his
Origin of Species, thus the tome does
NOT qualify as scientific literature ... no peer review, no refereed publisher, and there are a few mistakes ... in 1859, one needed the Church of England's permission to read a paper into the minutes of the Royal Society, something evolution didn't have back then ... one of the more important reasons we created the United States of America with our freedom of religion ...
