Confusion About Human Chromosome #2

[Bellabob]

 

The video above is what I'm having trouble with.

 

Our chromosome number 2 resulted from the fusion of two primate chromosomes. How does this suggest common ancestry?

 

Thanks.

The answer to your OP question is this statement:

 

"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"
