<strong>The</strong> above sources place Okapia in <strong>the</strong> early Pleistocene. Samo<strong>the</strong>rium however,<br />

according to current dating, lived 14.6 to 3.4 million years ago. <strong>The</strong> transitional series<br />

is missing, as in <strong>the</strong> afore-mentioned cases. And <strong>the</strong> okapi, "essentially a living<br />

Miocene short-necked giraffe" could – according to this assertion – be classified as a<br />

living fossil (basic form essentially unchanged for some 15 million years; on <strong>the</strong> topic<br />

<strong>of</strong> living fossils, cf. http://www.weloennig.de/mendel20.htm; see also Janis 1984 and <strong>the</strong><br />

fur<strong>the</strong>r points in <strong>the</strong> second part <strong>of</strong> <strong>the</strong> paper).<br />

"...split into Okapia ...and Giraffa (Pliocene), <strong>the</strong> modern long-necked giraffe."<br />

<strong>The</strong> long-necked giraffes first appear not in <strong>the</strong> Pliocene, but ra<strong>the</strong>r with Bohlinia<br />

attica (maximum 11.2 million years ago) and Giraffa priscilla (about 12 million<br />

years ago) already in <strong>the</strong> Middle Miocene. <strong>The</strong> end <strong>of</strong> <strong>the</strong> Middle Miocene is dated at<br />

10.4 million years ago according to Harland et al. (1990) and Kearey (1993), thus <strong>the</strong><br />

oldest estimates for Bohlinia and Giraffa reach back into <strong>the</strong> Middle Miocene. So far<br />

both genera appear in <strong>the</strong> fossil record without a series <strong>of</strong> transitional stages with<br />

<strong>the</strong>ir very impressive heights <strong>of</strong> almost 6 meters. Since <strong>the</strong> genus Giraffa, with an age<br />

<strong>of</strong> some 12 million years, is placed into <strong>the</strong> Middle Miocene, it can in any case be<br />

considered a living fossil.<br />

Now at this point, where <strong>the</strong> most thrilling part for our basic question begins, i.e. at<br />

<strong>the</strong> point, where <strong>the</strong> gradual evolution <strong>of</strong> <strong>the</strong> long-necked giraffe is asserted to have<br />

been documented by intermediate fossil forms ("...<strong>the</strong> evolution <strong>of</strong> <strong>the</strong> long-necked<br />

giraffe can be reconstructed from fossils" – see Kutschera above), we no longer hear<br />

anything about <strong>the</strong> fossil evidence, but only <strong>the</strong> assertion that this evolution has<br />

taken place ("...split into Okapia ...and Giraffa"). If, however, Kathleen Hunt could<br />

produce <strong>the</strong> fossil evidence for a gradual evolution, <strong>the</strong>n, given her desire to show <strong>the</strong><br />

public that all fundamental questions and problems on <strong>the</strong> origin <strong>of</strong> <strong>the</strong> long-necked<br />

giraffes have been completely solved in accord with <strong>the</strong> syn<strong>the</strong>tic <strong>the</strong>ory <strong>of</strong> evolution,<br />

so that only <strong>the</strong> ignoramuses and/or religious fanatics could doubt this fact, <strong>the</strong>n<br />

surely she would have laid it out in detail. However, she does not present <strong>the</strong><br />

evidence, because such a transitional series does not exist.<br />

Recently this last point was confirmed by a fervent defender <strong>of</strong> evolutionary <strong>the</strong>ory,<br />

we will call him Dr. Y, by answering my question "Is <strong>the</strong>re a series <strong>of</strong> intermediate<br />

fossil forms between Samo<strong>the</strong>rium africanum and Bohlinia?" (3) clearly in <strong>the</strong> negative<br />

("<strong>The</strong>re is not an intermediate that I am aware <strong>of</strong>"). Ano<strong>the</strong>r biologist – likewise a<br />

giraffe expert (Dr. Z) – said, to be sure, that <strong>the</strong> skull and teeth <strong>of</strong> Bohlinia are more<br />

primitive than those <strong>of</strong> Giraffa (when <strong>the</strong> term "primitive" is used, in my experience<br />

caution and fur<strong>the</strong>r investigations are advisable), but he added: "...but it is true that<br />

<strong>the</strong> post-cranials are about as long as those <strong>of</strong> <strong>the</strong> living giraffe." This author<br />

questioned <strong>the</strong> evolution <strong>of</strong> <strong>the</strong> long-necked giraffe Bohlinia from S. africanum and<br />

from his following statement "<strong>The</strong> ancestors <strong>of</strong> B. attica should ra<strong>the</strong>r be sought in<br />

Eurasia..." it is easy to conclude that <strong>the</strong> assumed series <strong>of</strong> evolutionary ancestors and<br />

transitional forms are unknown (because clearly: if we already had <strong>the</strong>m, <strong>the</strong>re would<br />

be no reason to search for <strong>the</strong>m – nei<strong>the</strong>r in Africa nor in Eurasia).
