iMmINeNt RApTUre, re Chromosome 2 .. if you were really interested in understanding
our origin rather than just providing sugary coating to cover your pile of bs you would have
posted something as this one, rather than your dishonest contribution on chromosome 2.

Do you see all the information here that your dismal obfuscation omits to mention? Your piece is a lie by omission.

Further information: Genes of the Chromosome 2 fusion site in chimpanzees

All members of Hominidae except humans have 24 pairs of chromosomes. Humans have only 23 pairs of chromosomes. Human chromosome 2 is widely accepted to be a result of an end-to-end fusion of two ancestral chromosomes.


Fusion of ancestral chromosomes left distinctive remnants of telomeres, and a vestigial centromere

The evidence for this includes:

* The correspondence of chromosome 2 to two ape chromosomes.

* The closest human relative, the chimpanzee, has near-identical DNA sequences to human chromosome 2, but they are found in two separate chromosomes. The same is true of the more distant gorilla and orangutan.

* The presence of a vestigial centromere. Normally a chromosome has just one centromere, but in chromosome 2 there are remnants of a second centromere. The presence of vestigial telomeres. These are normally found only at the ends of a chromosome, but in chromosome 2 there are additional telomere sequences in the middle.

Chromosome 2 presents very strong evidence in favour of the common descent of humans and other apes. According to researcher J. W. IJdo, "We conclude that the locus cloned in cosmids c8.1 and c29B is the relic of an ancient telomere-telomere fusion and marks the point at which two ancestral ape chromosomes fused to give rise to human chromosome 2."
