“it's a significant result,” says michael mcgowen, who studies the genetic evolution of whales at wayne state university “the work on aspm shows clear evidence of adaptive evolution, and adds to the growing evidence of convergence between primates and cetaceans from a molecular perspective. Both darwin and wallace were influenced by an essay written by economist thomas malthus who discussed this principle in relation to human populations third, darwin and wallace convergent evolution is the process in which similar traits evolve independently in species that do not share a recent common ancestry.
