Apes share 98% of their genes with humans. They are able to show symptoms of boredom, anxiety and psychosis; they form lifelong attachments and grieve when these are broken; they use language, think aloud, plan ahead, make moral judgements, deliberately deceive others, and remember the names of those whom they have not seen for years.Apes and humans should form part of the same community of equals. As with young or intellectually impaired humans, human guardians must safeguard the rights and interests of apes and act in an advocacy role on their behalf in the law courts and elsewhere.
