"If you look at cells from a human or other mammal under a microscope, you’ll
see big fat molecular complexes called chromosomes that contain our DNA. If the
cells are from a bird or reptile, you’ll see a few of these chunky chromosomes
but also a flotilla of tiny specks that look like broken-down pieces of
chromosomes or even specks of dust.
Those specks turned out to be tiny chromosomes, but their significance has been
a mystery for decades. I assembled a talented team of young genome scientists
to show that these “microchromosomes” are almost identical, and they represent
the ancient chromosomes of a spineless animal ancestor that lived 684 million
years ago."
