Thanks for the interest TB. The raw material for cranial outlines are in gif format; I made the superimpositions using Adobe Photoshop. I'll send them to your mailbox.
Q1. In particular, I have seen many of such statements, and they contradict each other. Ken Miller reviewed some of their opinions and point that creationists differ in saying which is ape and which is human:

Harun Yahya, my principal target (because he's Muslim) considers australopithecines apes and Homo erectus humans.
About the genus Homo, there are some authorities who assert their uniqueness (such as Richard Leakey). However the earliest Homo members did retain some primitive characters, such as a pronounced brow ridge (supraorbital torus) and a pronounced face (prognathism).
Q2. Some derived human characters opposed to primitive ape characters IMHO are: (ape state--modern human state)
*Brain size (small--big)
*brow ridge (more prononuced--less pronounced)
*canine size (big--small)
*prognathism (protruding face--flat face)
*locomotion (arboreal quadrupedality--habitual bipedality (australopithecines)--obligate bipedality)
*foramen magnum position (posterior--anterior)
*pelvis shape (elongate--box-like)
*vertical semicircular canal (small--large) (Fred Spoor's research)
*big toe (detached--attached)
Q3. Never heard of it. And I think that Dawkins & Gould couldn't have said that (if you may, I want to see where you find it)
Q4. You might be referring to
Lee Spencer's article. However, I find that claim rather implausible, because given the dates of known transitional human fossils (dating back to 7 M.y.a.), then to say that the transitionals were born from human-ape matings would require that this behavior lasted for millions of years, and the supposed hybrids were getting more humanlike than apelike as time goes. There is a proposed theory (I guess it was by Mayr) that the existence of species is life's way of maintaining adaptation and fitness.
Anyway, if you believe that man is separately created, was he created as Homo sapiens? Or maybe you would include erectus and Neanderthals as well?
