How is it that the environment (predators in this case) can somehow influence a flea to create a new spine without the flea (or his parent) sensing the predator? What do you think does this sensing?
Fish do this all the time: upon an environmental chnage many fish can change colors on a dime. Cichlids are notorious for this. How does this happen without some sort of sensory device to not only ackowledge the new environment, but also to signal the necessary morphological changes? |
What about eggs then?
hOW come they be all different colours like? |
show me the mutation....why would the darker (or lighter) be any more selectable than the other?
