Where Reside the Intermediaries 
With gradual evolution, there should be hundreds of millions of intermediate forms between each
of the major species, both living and in the fossil record. But we see no animals with 20%
feathers and 80% scales. No partly formed eyes or fins or wings or legs. Nowhere in the fossil
record is any such transitional form. Why are the "primitive" forms still around
today. Should not those better able to survive totally replace them except in the fossil record?


This is an argument against Darwin's original hypotheseis of gradual and continual change. We now know this is not how life reproduces. At the right time span, just after a catastrophic event there are lots and lots and lots of intermediate forms. Then things stabilize. And partial items? Bit's and pieces of body plans get reused by later generations for other purposes. There are examples of eyes ranging from vague light/dark sensors to the best of eyes (found in the octopus, poor humans have a blind spot). Detection of light is so usefull, even in crude forms that eyes have evolved completely from scratch a half dozen times in different animal families (and some plants too).
