Apparently the largest know genome size in the world now belongs to a variety of fern Tmesipteris oblanceolata. Whilst humans have 3.1 billion base pairs in our DNA, this plant has 160 billion!
It seems to add to the power of the "onion test" that basically argues that if someone wants to claim that most or all of the human genome is functional and necessary, they need to explain the same in these other genomes of what seem more simple organisms. If they can't do that, for these larger genomes, why assume that all the human genome or other animal's genomes must be largely necessary, and the product of good coding.
