The Case for Junk DNA

Figure 1

Summary of haploid nuclear DNA contents (“genome sizes”) for various groups of eukaryotes.

This graph is based on data for about 10,000 species [18], [19]. There is a wide range in genome sizes even among developmentally similar species, and there is no correspondence between genome size and general organism complexity. Humans, which have an average-sized genome for a mammal, are indicated by a star. Note the logarithmic scale.
