The grasshopper, he noted, sports long legs and wings, walks low and slow, and dines discreetly in solitude. The locust scurries hurriedly and hoggishly on short, crooked legs and joins hungrily with others to form swarms that darken the sky and descend to chew the farmer’s fields bare.
Related, yes, just as grasshoppers and crickets are. But even someone as insect-ignorant as I could see that the hopper and the locust were wildly different animals — different species, doubtless, possibly different genera. So I was quite amazed when Rogers told us that grasshopper and locust are in fact the same species, even the same animal, and that, as Jekyll is Hyde, one can morph into the other at alarmingly short notice.
An interesting article that is closely related to the last one I linked to. It seems that genes are not the whole story in evolution. That said, the title is a bit misleading since it implies that the selfish gene metaphor is wrong, when in reality it’s just incomplete. Gene expression plays a crucial role, including it’s turning out, a heritable one.
I’ll admit a reluctance to giving up the gene only model, if just for its simplicity, but reality isn’t interested in our desires, and a commitment to truth often requires embracing complexities that challenge our paradigms.
