>Human chromosome 2 has a vestigial (unused due to no longer being needed) extra centromere and 2 vestigial telomeres found inside the chromosome sequence.

Goddammit that's cool.

I can't be sure of it quite yet, but I have a feeling sequencing the entire genome is the single greatest human breakthrough in my lifetime. I was in middle school when my science teacher told us it had been done for the first time. When I was in college I toured a sequencing facility where it was being done for outrageous cost per sequence on machines bigger than my house. Last year I got my own DNA fully sequenced, every single base pair, for about two day's wage.

Reading your own ancient programming code letter by letter is a weird, almost disassociating experience.
