Darwin himself recognized in Origin of Species that his theory had many difficulties. He listed four objections that he recognized, if not resolved, would be fatal to his theory. They were, in order:
The lack of transitional forms
The incredible complexity of such organs as the eye
The development of instincts in animals
The sterility in crossbreeding of species
try that on for some real MEAT!!
incredible complexity
that mean nasty term used by CREATIONISTS
how did the first EYE develop?? the smart lil amobea KNEW there was something to SEE......out there did they??
There are an abundance of transitional forms. The evolution of the eye from a cell sensitive to light is in the fossil record. Instincts and cross breeding are covered in the tree of life. There is a point in speciation when the two creatures can no longer breed. Burros and horses.
