Researchers were unprepared for what they would find when they recently
completed sequencing of the chimpanzee Y chromosome, and compared it to the
human Y chromosome.
“The Y is full of surprises,” said David Page of the Whitehead
Institute for Biomedical Research in Cambridge, Massachusetts. He and his team
had just found that the Y chromosomes of chimps and humans are
“horrendously different from each other”.1,2
Why did Dr Page use the word “horrendously”? Because he believes
evolution—that chimps are our closest evolutionary relatives. But
Page’s team found that the chimp Y chromosome has only two-thirds as
many distinct genes or gene families as the human Y chromosome and only 47% as
many protein-coding elements as humans. Also, more than 30% of the chimp Y
chromosome lacks an alignable counterpart on the human Y chromosome and vice
Upon seeing these and other stark differences between the respective Y
chromosomes, Page now says “the relationship between the human and chimp
Y chromosomes has been blown to pieces”.
However, that doesn’t mean that Page and his research colleagues doubt
evolution. Indeed, the cleverly spin-laden announcement in Nature journal
heralded that “Rapid evolution distances chimp Y chromosome from human
equivalent”.3 But Page’s language tellingly invokes creator-like
powers to explain the chimp/human genomic origins: “It looks like
there’s been a dramatic renovation or reinvention of the Y chromosome in
the chimpanzee and human lineages.”
It surely makes much more sense that the “extraordinary
divergence”2 of the human and chimp Y chromosomes has nothing to do with
supposed evolutionary ancestry but everything to do with having been designed
that way. Design explains not just Y chromosomes, but why (there can be)
chromosomes. They certainly didn’t happen by accident
(Genesis 1:26-27, Romans 1:20).
