The continental-drift hypothesis was ridiculed and ignored for decades (see krilldrift.com) until advanced paleomagnetic technology suddenly 'proved' it. Likewise, the aquatic-ape hypothesis has been ridiculed for decades, and the Bioko version is being ignored. But advanced DNA technology is now available that may be able to 'prove' it. 

About 5-8% of the human genome consists of endogenous retroviruses (ERV). Bioko has endemic animals—subspecies not found on mainland Africa. If the human genome includes one or more ERVs that are only found in the genomes of animals on Bioko, the aquatic-ape hypothesis would be difficult to deny. 

ERVs are not limited to primates. But here are some of the primates that may be studied: http://bioko.org/primates.html
