I, the undersigned, hereby reissue my challenge to parties:
-SF_GoldG_01
-Obi_Kwiet
-Any other takers
, henceforth to be called 'the creationists', concerning the chromosome challenge, first issued as per (a).
The creationists are given a deadline of one (1) month, starting the fourteenth (14th) of January, 2006, effectively ending without defense on the fourteenth (14th) of February, 2006, 22.00 GMT. Should the time period required exceed the legal three (3) weeks, as defined by (b), the creationists shall start a new thread with their formal and ultimate response.
Failure to meet the proposed demands will allow the silence to speak for itself. Opposing parties, referred to henceforth as 'the scientists', will make claim to their right to point and laugh, and refer to the silence mentioned above in a humiliating manner. This right has no expiration date.
The challenge is reissued in a shorter, more comprehensible version below. Source is referred to in (c).
Long long ago, in a laboratory far far away, scientists figured out that chimpanzees have 24 chromosomes in their sperms and eggs, whereas humans only have 23. Therefore, these great scientists theorized that two of our chromosomes might have fused together sometime in the recent past (aka million years ago.). Their theory made 3 predictions:
1) One of our chromosomes would look like two of the chimp chromosomes stuck together.
2) This same chromosome would have an extra sequence in it that looked like a centromere. Centromeres are the things in the middle that microtubules grab onto to divide a pair of chromosomes during mitosis.
3) It would also have telomeres (ends) but in the middle - and they would be in reverse order. Sort of like this:
ENDchromosomestuffDNEENDchromosomestuffDNE
See the "DNEEND" in the middle? That's what two telomeres would look like if two chromosomes were stuck together.
Lo and behold, these theories were put to the test. To test prediction 1, know that chromosomes all have a unique banding pattern. A "fingerprint." To test 2 and 3, you need sequence data. Telomeres and centromeres have characteristic DNA sequences.
What did those scientists find:
H=human, C=chimp, G=Gorilla, O=orangutan.
and
So how about it, non-evolutionists? Here, staring you in the face is not only evidence that chimps are our cousins (they may explain your last family reunion) but also a clue as to how it occured: two chromosomes fused, which could have altered gene expression in ways to change body plans.
Happy refuting!
