Fig. 4. Rates of segmental duplication.

Fig. 4

a) By basepair: We parsimoniously assigned the number of Mb to different branches, correcting for copy number in each species (shown in brackets). 89-99% of great-ape segmental duplications were validated by arrayCGH (square brackets). b) Further categorization of the segmental duplication data, based on arrayCGH from bonobo and gorilla, shows the greatest accumulation in the ancestor of humans and great apes. c) By event: We assigned 950 evolutionarily distinct human segmental duplication events20 to the human/great-ape phylogeny based on arrayCGH results. The red line estimates the duplication rate (per million years) and suggests an excess of large duplications in the common ancestor of human and chimpanzee but after the separation from gorilla.
