Why don't you quote Darwin directly? His works and letters are all on line and easy to search.
Why do you continuously quote only from fundamentalist websites? You know they are not doing science; rather, they are committed to doing apologetics.
If you are going to argue science, you need to start reading scientific sources.
The last site I gave you is not a creationist site. A better question is why don’t you look it up yourself. It’s pretty obvious you have not read Darwins book or you wouldn’t be trying to deny one of his main tenets.
