"( 6 ) Natural selection supposedly accounts for the development of new kinds , but actually tends to preserve the present kinds , since an incipient organ or new feature of any kind would have no `` survival `` value unless it were fully functional from its very beginning ."
"Actually , natural selection tends to preserve a species with only minor changes in a stable environment . But environments tend to change . I do n't know what that `` incipient organ `` junk is supposed to mean . Is that another way of saying `` what good is half a wing. `` Well , check out a penguin to find out . Look at a seal flipper . It has the same bones , arranged in the same way as a monkey . What good is it for a land animal ? And what does `` fully functional `` mean ? What function ? Perhaps the new organ had a different purpose - take the clawed hands of fossil birds for example . They were good for catching prey and climbing , just like they were for their dinosaur ancestors . But those clawed wings also allowed early birds to fly ."
