Giardia is eukaryotic yet is long thought to lack a mitochondira.  Recently, researchers have found that each Giardia cell contains double membrane-bound organelles similar to a mitochondria called mitosomes that lack mtDNA.  What is the best explanation for mitosomes?

▸ Mitosomes are the ancestral form of the mitochondria.

▸ Mitochondria in Giardia evolved into mitosomes and have lost or transferred their DNA to the Giardia nuclear genome.

▸ Mitosomes evolved from another Giardia organelle that lacked DNA.

▸ Mitosomes are more advantageous to eukaryotes than mitochondria.

▸ Giardia are asexual and thus do not require mitochondria with its own DNA.
