If we look at the origin of our species in the context of Zimmer’s article on the origin of ants, the differences clearly come down to those associated with single base pairs and amino acid substitutions. Those differences are part of a continuum of experience-dependent nutrient-dependent pheromone-controlled adaptations. That fact explains why a human population that has adapted to conditions in what is now central China exhibits differences in hair, teeth, skin and mammary tissue.
Only the differences in teeth, however, are likely to show up during examination of remains from ~30,000 years ago. But even if fossils or other tell-tale evidence of changes in teeth are not found that link our ancestral line across 1.8 million years, we still have a model of nutrient-dependent pheromone-controlled adaptive evolution to rely on for its explanatory power across hundreds of millions of years. The model can be compared to mutation-initiated natural selection and its lack of theoretical explanatory power.
Or can it?
My question to Carl Zimmer remains the same as evidence against mutation-driven theory continues to overwhelm theorists.
Do you think there is a difference in the evolutionary origin of ants that can be compared to differences in the origins of Homo?
My comment is the same, too. I think the similarities in the molecular mechanisms of thermodynamics and organism-level thermoregulation that link the epigenetic ‘landscape’ to the physical landscape of DNA in the organized genomes of species from microbes to man are more important considerations.
